what velocity loss expected

Dragging up an old thread...

I was doing some research, and came across this old thread I had started, and was interested in the replies.

Now, I get that a lot of folks post opinions as fact, but have never done their own testing, or have not researched other's testing.

But as I enjoy all aspects of firearms, I read a LOT, because I simply cannot afford to do a lot of what I find interesting.

Anyways, to address KodiakJack's comments, my replies are in bold.

. Uh... Barnes original had lead exposed on both ends.
Corbin MFG has dies that make tube bullets with exposed lead on both ends
Ross Siefried (?) (sp?) had an article about using copper tubing rings around a cast bullet, and never mentioned leaving a ring in the bore
Also, there was a manufacturer who made a bronze tube bullet with a nylon base, and there too, never a mention of leaving a bullet in the bore

I wrote that 3 years ago dude. In those 3 years, if you haven’t worked up the courage to grind the tips off cheap steel core surplus ammo and use them on game, what does that tell you? It’s your gun, your fingers, your eyes. Do with them as you please.

KJ: As for critters, if you plan to poke a hole in anything bigger than a gopher, please PM me, and I'll personally buy you a proper bullet. I respect tasty critters, and they deserve a better end than what a bubba bullet may provide.

A LOT of hunters shoot fur bearing animals with FMJs..... some a little bit bigger that a gopher!

Well... you’ll see that I was specifically referring to “tasty critters” (hunting for food) not fur bearers. I don’t consider yotes tasty. I got the impression that you planned to grind the tips off surplus so you could hunt for food because you said exactly that:

Hey kids. Sorry it took so long to get back here.

I think it was ganderite, now that he mentioned backwards bullets, that led me on the trip to find out more about the 303brit using the pulled bullets and recycled powder.

As for why? Powder is getting expensive and the x39 already has some! Bullets are not cheap. And with surplus going for less than the price of heap bullets.... Well why not?

I have read enuf from guys I trust to try this as stated.

Pull bullets. Dump powder directly over. Seat bullet. If I was going to hunt for food I would burn the tip off in a sander or file.

My offer still stands. If you want to shoot a deer, give me your address and I’ll mail you a goddamn bullet.

I have personally experienced the core leaving the jacket when shot, and the jacket remaining in the bore.

Fortunately for me, the jacket was lodged close enough to the throat that I could not quite chamber the
next round. Ironically, it was in a 30-30. I poked out the jacket, and was surprised that the core had left.
The hole in the base of the jacket was only about 3/16" in diameter.

I can only imagine what the result would have been had that jacket been just a bit farther up the bore.

As for shooting pulled .310-.311 diameter bullets in a .308 bore, no issues whatsoever. Shoot away!

Interesting (and scary).

So this was a soft nose, factory bullet? You think the cup was just defective and had a hole or weak spot in it?

depends on barrel length and how fast your barrel is. Is it pitted or glass bright? also depends on powder type and charge weight.

Yes, and I believe the cup was defective, or weak at it's base. It was an old C.I.L. 150 grain SP round. Dave.

Did it sound funny, or give any other indications that there was some bad mojo?
