as for strength?? id say a Nickle steel 03 or A3 beats the 40x, 700, ect.
iv drill into all of them, and welded on all of them...
the strongest??by far the Smith Corona A3..they hardened them through and through.
Remington A3, 40x and 700,s were only surface hardend
pic is of a 68 vintage 700 im rebluing for a guy that left the rifle in a soft case. stored in his camper, with a leaky roof...yes, it was rusted to the case..
still to this day cant understand why anyone would store a firearm in a camper, let alone a cheap naugahide case... keeps my pockets full for sure.

Good looking blue.

Have you ever polished and blued an 03A3?

a few, thats not blued yet,, just started removing the rust pits...it will be blue by next week.
i parkerize rifles that should be parked...i dont do many sporter 03,s anymore.
im more geared for restoring them back to milspec. weld them holes shut, make em look the way they should.
hunt with that Remington 700....its already drilled for the toys..and leave them old guns alone, lol.

Jim, I've looked at a few Lyman 48s and from what I've seen, the 48C came with 30,60,90, and 125 slides. I have a Lyman 48S, which also fits the 1903s, and the longest slide, which I have is a 105. Maybe Jim Tarleton, or someone else knowledgeable about these sights can help out.

Long Slide Lyman 48

NMC EXP,
What you have I believe is a post WWII “long slide” Lyman 48. Per my memory the post-WWII Lyman 48 came in two sizes. To quote from the Lyman catalog:
Series 48 Receiver Sight with standard elevation slide (up to 600 Yard)…$12.50
Series 48 Receiver Sight with special long slide (up to 1000 yards) ……….$14.50
The standard slide was calibrated to 60 minutes while the long slide was calibrated to 105 minutes. I still have a “long slide” on a M1903.
I do not know how much windage adjustment the new 48 has but it’s more than plenty.
I believe that the pre-WWII 48’s were calibrated TO 125 minutes

Bill thanks for the info. I did not know there were so many versions out there.

Thanks....based on the angles of elevation table in Crossman's Book of the Springfield, I thought 105 minutes was enough for 1000 yds.

The one on the left is one of the prototype 48's the other the 48 made from 1911-18 sight.

Lyman 48 1000 yd adj

To continue the discussion on the “Long Slide (105 M) Lyman I shall relate the following information. I once belonged to a rifle club that had a range with 30 targets to 1000 yards which I shot almost weekly and one of the rifles I used regularly at that range was a M1903, with a standard issue 24 inch barrel and a” long slide” Lyman 48. I believe that the Lyman was originally calibrated for the M1903 with the 24 inch barrel. If the barrel is longer than 24 inches, the adjustments will be less than MOA and if the barrel is shorter than 24 inches , the adjustments will be greater than MOA. The ammo that I regularly used was either FA or LC 30M72 Match ammo or hand loads loaded to an equivalent velocity using the 30M72 bullet.
I initially sighted the rifle at 200 yards and set the sight to +2 elevation. The settings were:
200 yards= +2
300 Yards= +4 (come up from 2 to 3 =2 MOA)
600 yards = +11 (come up from 3 to 6 = 7 MOA
1000 yards= + 27/28 (come up from 600 to 1000 = 16/17 MOA)
So I think that the 105 minute calibration will provide plenty of elevation for 1000 Yard shooting. I never ran out of windage and if you have never shot on ranges in West Texas, New Mexico, or Arizona, you can’t imagine how the wind blows. I have made up to 6 minute changes from shot to shot.
Hopoe this provides some useful info.
