Solution to Shots Stringing at 45 Degrees

Sat at work all day pondering my problem with my new rifle stringing its shots at a 45 degree angle (previous post). Came home, neck sized a case, stuck a bullet in the end of the empty case and chambered it. Bullet is a 165 gr boat tail, and only 0.045" of bullet bearing surface was in the case neck.

It was getting dark so I loaded up 5-rounds real quick using this bullet seating depth (really long rounds - won't fit in magazine and they look like little ballistic missiles) with a light crimp. Fired two rounds - side by side POI's:beerchug:, third round had primer in sideways:dunno: (I know, I know) and blew gas and a surprising amount of smoke in my face but did not detonate powder, fourth round didn't fire at all (I suspect glycerin on my hands while loading primers):nono:, and fifth round hit beside first two:D. Three shots covered by a quarter 1" to the right of the bullseye and primer dust in my face (I was wearing shooting glasses). Either the throat is worn to bejeezes, or it has been throated big time.

Three shots prove nothing, but I suspect I have found my problem. I think someone was shooting some very long and heavy bullets. I will fire much longer strings tomorrow while you guys are at work.:thup:

Jim

What the hell is that thing? :) Cowdeer, deerholstein ??

Another solution to your shot-stringing problem is to pin up a deer in a small confined cage so you can get closer. :nono: And splash some white paint on it so that it's not so hard to see. :madsmile:

J.B.;)

Did you try looking at the rear scope mount as suggested? Just curious. I guess since you will be loading cartridges and shooting this weekend, then JB and I can have your portion of the BBQ ribs???
Good Luck with the rifle. FWIW, 147gr. BT bullets for the 7.62 nato round won't shoot worth a dang in a 1:10 twist Springfield barrel.

Later,

Emri

John, you are a hoot!! I was going to tell swamprat that it is just a pet and don't worry about what it is!! But I didn't in case Jim had a better answer.
FWIW, I have a pet rabbit that my #2 son brought home when he was 8yrs. old. They swore that rabbits don't live more than 5 or 6 years. #2 son will be 21 yrs. in July. The rabbit is still alive. They say it's MY fault because I give him a carrot every night. Maybe we should eat carrots instead of ribs???

Hey Jim! Tough audience!:move eek:

I did indeed check out the scope - no problem there.

That is a full grown North Carolina piebald deer. They are born that color and stay that color, and they have a hunched back, humped nose, and twisted legs. I think they are also all females, but I'm not certain on that part. The little deer has been released in heavy woods along the Black River on private land. I was getting very attached to her (I am a NC wildlife rehabilitator). Incidentally, small deer are very hard to keep alive, as they nurse for almost a year. They are like little bulls as they "bump" the udder, and that "bump" would knock the wind out of you. Ditto for little squirrels, but I have sworn off squirrels since the last hurricane brought in over 400 at one time.

I am going to miss those ribs, and the company, and I was bringing each of you a whole bunch of frozen squirrels!. I had some neat stuff to show you guys too (RB rifle, Niedner rifle, etc.). The person I found to take care of the farm in my absence backed out at the last minute.

You have probably already thought of this, but here goes anyway:

For that particular rifle I would try 180 Gr. Hornady pointed soft points <> they are "flat base" & not boat tail. They have a long parallel bearing surface. I have used them for years.

By the way; Today I "FINISHED" the last bit of that special Super Bowl Venision Chili and washed it down with a suitable St. Pat. beverage. :yikes: :beerchug:

I would also liked to have gone to Birmingham. A friend, from Dallas & a M1 Carbine guy, will be there.

Don,

Pardon me for not personally inviting you. :bow: But please understand that you have a standing invitation. :cheers: We would love to have you! Just let us know when to expect you and we'll hold you a place at the trough, er table.

J.B. :beerchug:

Jim-

Pretty palomino you have there. Never seen one in the mountains, yet.

Hope you raise him right.

Spring is here, so I may have to get out my Remington sporter and see what happens. It's a blaster and I need to blast somethin'. Got my eye on a can across the holler. Submitted below, a new use for the old, broken mason jar. And a modified hunk of an Oregon volcano.

Happy spring to all.

PD

Obsidian has the property of having exceptionally sharp fracture edges, and has been used in some surgeries here in the states. That Mason jar point is just unbelievable, even though I can plainly see it. Were they particularly hard to chip?

I released the Palomino on private land. They do not good pets make, and they deserve their freedom. They are indeed extremely rare in the population. I have released all creatures rehabilitated except for two, V'ger, who became fearless of dogs which is a death sentence here, and Tiger, who cannot walk nor feed himself.

I am one of those people who believe that wild animals should not be domesticated, including elephants. Fortunately, elephants have the ability to punish their captors, as do many other wild animals - like chimps? Unfortunately, it cost that chimp his life.

I have been attacked by buck deer twice in my life, and I can attest to the fact that they have the ability to put your lights out permanently. Both were "pets" raised from fawns who attacked without any warning while being fed. Their speed and strength are awesome and frightening to experience. If one believes he is going to grab those horns and throw that deer to the ground, he is an utter fool. The buck will throw up his head if you grab his horns, which raises your arms, and then the buck will charge, which leaves your chest and face exposed to great harm. I can throw a cow or horse to the ground by reaching over its head and grabbing his chin and pulling it back into his neck (ala Clint Eastwood in "Josey Wells"). Both animals will fall to the ground/lie down. Not a buck. He will jump straight up, spin around, and nail your a$$ with a speed that will dazzle you.

20 rounds on one target today has convinced me I have yet to find the solution to my problem, although the spread has decreased dramatically. I have one more trick to try.

Jim

Jim: make sure you have 5-8 lbs of forend tip presure on the bottom of the barrel and the barrel is not touching any where else,also make sure the upper band is not touching the barrel.Tis is the method used on NM guns. hope this helps you

Make sure the trigger guard screws are tight but not to tight.

Jim- I am out of the loop as they say....

What rifle are you describing? Please enclose a pic and description some time. I rarely get any new rifles these days(pegged to the dollar and adjusted for inflation), so must live vicariously through others. I can get jazzed by a pile of flint though and that is cheaper.

I need to build a gun this year. Reckon I'll shop for a receiver and go from there. My franken-builds are one hundredth of yours and Darrelds but at least the bullets come out the right end.

Also, I like bananas (pic.)

Ahhh, V'ger. She is a little hussy. It is Spring, and she is getting "that way". She gets a little b*tchy, if you know what I mean.

Nice looking RB rifle there!

John,

Thank you very much for the public invitation. I do want to make the trip some day. It looks like about 650 Mi. to Birmingham, which makes for a long w/e trip.

2008 & this year have been eventful for me. In addition, my Son-in-Law (46) was diagnosed with stage 4 colon cancer & it has spread to his liver, so we have been hanging close to home.

At your show, look up my friend Alan Sinz (with the M1 Carbine guys).

Best regards, Don :beerchug:

Don,

I just got your message. Ironically, I did indeed see Alan today. You would not believe the coincidence!!!!!

We first met on Friday at a place of mutual interest. We were both standing at a copy machine. He asked for and I gave him some sheets of information I happened to be copying. You probably know the ones I'm talking about. And I bumped into him again today at the show and he recognized me. He told me that he had accidentally left behind the sheets of information I had given him and was most apologetic and regretful. I surprised him when I pulled out a second copy from my backpack and gave them to him. I think I made his day.

I asked him if he knew you. And as you know, he did. So, I asked him to convey my greetings the next time he saw you.

Small world. Thanks for the message!

J.B.

p.s.,

And I may be able to help you with your transportation challenge. Just let me know well in advance when you want to come.

p.p.s.,

I am very saddened to hear about your son-in-law's situation. Things like that are not supposed to happen. I extend my prayers and best wishes.

that hung around with his harem in and about our Peacekeeper stage processing facilities. One evening on the swing shift, there were a few whitetail does hanging around, as well, and that little white buck mounted one of the whitetail does. Not sure which one was confused, but it indeed happened, and NO, I hadn't had my medicinal dose of group tightener that evening! I hadn't considered the possibility that such an event could actually produce offspring, but that ugly little critter you got penned up in the photo could've been his little one!!!
No help with the 45 degree cant of your string, but considering the beatin' yer ears most surely took while ridin' the rails on those 155's, maybe the brain housing group is canted!?
Only useful suggestion I actually have is to check that the bottom flat of the receiver is bearing full and not twisted in the wood, nor vise-versa. I'd have to believe that there's a high spot somewhere in the barrel channel that's pushing the barrel when it heats up, causing the stringing.....
What I've done to some sporter projects is to mark and file the top edge of the magazine box down so that I get about two playing cards' worth of clearance between it and the bottom of the receiver, and using a shim under the rear tang like Remington did on their rebuild program......Regards, Darreld.

Jim. try this real basic fix,
remove the tang bushing, trim 1/8 off the end, spred it a bit, push it back in the stock, and try another group.
let us know if it works..

In my determination to resolve the issue, I have been doing one heck of a lot of reloading and shooting on a daily basis. I even completely rearranged my loading bench and found stuff I thought was long gone, including a hundreds of bullets I didn't know I had. I had them in the bottom of a box I had begun to use as a trash receptacle. When I dumped the box into the trash can, I noticed its weight was way more than it should have been, and upon investigating, I found over a dozen boxes of bullet of various caliber.

I have been practicing on a daily basis, and I must admit my shooting ability has improved. Now if only my eyesight would improve, I would be truly dangerous. I have gotten the rifle to group around three to four inches, but I am determined to do better. I took the rear receiver screw completely out, and the groups improved. I trimmed the front screw by a few thousands and the groups improved. I put a card under the front of the barrel and groups improved. I have gone from a 6 to 7-inch consistent lateral grouping to a four inch dispersion from a rest (10-shots). Oddly enough, the first shot is always slightly low and to the left, and the second and/or third shot is usually in or touching the bullseye. As the string continues, dispersion increases, which tells me something is touching the barrel or something is twisted which is affected by heat (as Darreld said).

Jim

Jim,

Be sure to check the stock, in the barrel channel where the shaft of the lower band spring goes through the stock. Many times, the hole and the spring seem to be drilled and located a little high and it ruptures the wood in the barrel channel. << OR; the action inletting & barrel channel are too low.

Sometimes it is off by so much that pieces of wood are mising and the spring shaft is visible and invades the barrel channel groove. I have seen numerous cases where the bottom of the barrel hits the spring shaft & actually causes a transverse worn spot on the finish of the bottom of the barrel. :banghead:

I forgot about that little spot, Don! Good call! Darreld
