Jungle carbines are LOUD...

[oney]

... at least that is what my wife said when I touched mine off behind the house a short time ago. If I can get the ole girl to shoot the way I need and in a safe condition... she should be a real interesting piece on the line at Camp Perry this August.

I have a FMP marked BSA No5 Mk I, that I was test firing behind the house earlier. I didn't want the hassle of cleaning up after using corrosive ammo, so I grabbed a box of Sellier Bellot (180gr FMJ) I had purchased awhile back at a local shop. I fired eight rounds... I had a couple of cratered primers, and then everything looked good, nice dented primers, then on the eighth shot... WOW... the ole girl kicked like a mule... boogered up my thumb... and when I looked at the case, the primer had backed out a tad with a small puncture.

I'm not sure whether it's a headspace issue, or if the ammo is the issue. Some rounds kick... some don't... very inconsistant. Has anyone else used or had issues w/ S&B ammo in the green box w/ a gold end?

Any suggestions are appreciated... Thank You!

Yep....everybody LOVES a points-feeder! At least folks will know you're there.....more damn flash and noise than anything not crew-served and on tracks!

Albanian 7.62 x 54R in an M-44 Mosin Nagant is impressive, too. Carl

I would first get the headspace checked.

Yep.....the only one that gives the No.5 a run for it's money in the "Sturm und drang" department!

The only "Field Gauge" for the .303 I have on hand is a Brownells model which measures at .070. My bolt will close on this guage. I added a shim bringing the gauge to .072, and my bolt will not close on it now. I am of the understanding the the standard military fail measurement is .074. Am I correct? Is there a chance that the factory loads are hot, or should I look somewhere else for a problem? No out of the ordinary stretch of cases ect... just the puctured primer on the one case.

I´b be a bit worried if mine did that. Definitely needs looking into.

If you think the No5 is loud, NEVER shoot a Swedish mouser carbine!

oney, I just checked a pile of S&B 180 gr. emptys. All were fired through one rifle and there are a few primers more deeply struck than the majority. While firing there were no 'memorable' rounds. Another pile of UMC emptys, fired at the same time, same rifle were all normal.

Firing pin protusion should be .045", IIRC (I'll be corrected if wrong) and with one well worn Long Branch I had to round off the firing pin's tip as it was piercing primers.

A No.5 at Camp Perry? Sounds like fun.

This one barks a good bit louder than my #5 rifles! .308 Win with 20" barrel and a healthy dose of Reloder 15 under a 165 gr. slug. Of course .308 Win. operates at a good bit higher chamber pressure than .303 so I might be comparing apples to oranges.
