    I happen to have one or two 303 Lee Enfields. One of them at least shoots lightweight (147gr) plinker loads which are subsonic, very quiet with a suppressor and accurate to boot, like, centre of beer can at 40 - 50 yds from the shoulder. Trouble...

    I am also interested in the neck tension question. I have loaded rounds with zero neck tension and they seemed to shoot Ok. I've done this with jacketed bullets too (forgive me for I have sinned) and I have recorded sub MOA. I need to redo that...

    I have heard of a Lee Enfield (I would think an SMLE since it was from a WWII armourer - my uncle, although he never said it was) that apparently had a pull through cord left in the bore that split the barrel from chamber to muzzle. I think it was...

    Not to mention the shock from a near detonation. Here is another split chamber. And action. And everything else. http://cdn0.wideopenspaces.com/wp-content/uploads/2014/12/762d15.jpg

    I wonder what the actual load was? Realistically, how much Unique would it take to do that to a chamber? Or would a second bullet/boolit sitting in front of the chambered one be enough to split it, even with a brazed rear sight?

    I once shot a very impressive group with a five-groove No4 barrelled MLE - 1.15 MOA, seven shots. Not 100yds though. The boolit was a smooth side tapered 220 gr with gas check over 35.5 gr of Varget. They were lubed by dipping the boolit noses in...

    I have some 780 - I wonder if that would work with heavies?

    Don't get too hung up on the headspace issue with the P14. Lube the loaded cases with something like STP smoke stopper and give them some pressure. The STP will allow the case head to settle back onto the bolt face and set the shoulder forward for...

    I've mentioned the combatant who took three AK rounds to the chest at close range and lived to tell me about it. I've also mentioned the 7.62 fmj passing through small critters (cat size) and not stopping them while the 5.56 blew those same...

    303Guy replied to a thread Mosin Nagant shot out? in Cast Boolits
    I have a rifle (not a Mosin) with a bore like that although the bore is not rough, just worn. It shoots paper patched boolits just fine, with near MOA groups at 100m. That was with a throat fitting paper patched boolit. The boolit base shank fits...

    I have tried Varget in a 303 Brit under a heavy boolit. The group I got was as good as the movement due to my heartbeat. I'll look up my load. Of course the 8x57 is considerably larger than the Brit so pressures in the 8 may be too low or...

    I have samples of fired boolits that have lengthened by being squeezed down in the bore.

    That is interesting, thanks. 12,000fps! Holy cow! That would get hot but no doubt those projectiles would not be of standard construction. To actually catch fire! Remember the space capsule re-entry heating from the early days. The heat...

    The lead core only melts if the bullet stops suddenly. Like when it hits hard soil or a steel plate. It is nowhere near molten during its flight. Warm to hot maybe from its passage through the air, not from powder heating. Remember the SR73...

    It's a soil with small spherules of weathered rock. It has a name but it eludes me. Anyway, it's dry and stops bullets pretty quickly. And that's the point - stopping the bullet quickly converts its kinetic energy into heat energy. Fragments of...

    It was about the hot burning propellant gases melting the core in the bore. I mentioned that I had experienced jackets landing in the pit after striking the berm. I brought up the question of whether the kinetic energy was enough to melt the lead...

    Which is what one can see in the video I watched. Thing is, the core has to stop dead for the kinetic energy to be converted to heat. A lead boolit does not stop dead, it deforms and flows and splashes out so the energy is merely being redirected....

    This is exactly right. The only way to melt the lead core would be to suddenly stop that bullet so that the kinetic energy is converted into heat energy. That assumes the bullet has enough kinetic energy after losses.

    Just a thought - the black powder guys with 45-70, load to bore size and the boolit bumps up to fill the grooves on firing (I'm open to correction). Some of these guys are shooting 800 yd gongs with them.

    Hi Edwin. I'm going to have to think on this for a while. I wouldn't worry about boolit deformation as it leaves the muzzle if accuracy is good. It would depend on muzzle pressure which should be low enough with only 20 gr of powder. ...

    In the video I was watching there was what appeared to be mostly plastic deformation but some impacts showed distinct liquid from the nose area of the bullet. Any melting would be the conversion of kinetic energy into heat energy on impact. ...

    I have been thinking that a softer alloy may be beneficial in paper patching. I've found that it takes more pressure/velocity to disintegrate the patch with a softer alloy. The core conforms to the rifling better. I'm not sure what the downrange...
