Why couldn't I use 303 British for hunting?

[HeadDamage]

I've got some 154gr 7.62x39 wolf ammo that I'm fairly sure has an open lead base and a lead tip.

HD - Otta save those, Optics Planet says they're Out of Production. Didja pull one to see what the base is ? And the 'Tula' flavour is bi-metal jackets so ?maybe? the steel is stronger if the wolf are the same mfr ?

My great grandfather was an outfitter here in BC. His main rifle was this 1895 in 303 British. Lots of game fell to that rifle.

I pulled one years ago, don't recall anything of note other than the base being lead. I've got a few boxes of it still.

So Callee, are the PPU rounds FMJ or SP ?

both type of bullets where available

This is a Parker Hale, I picked up for a friend. I liked how it shot, so I got a Long Branch 4 MK1 *

I mentioned that thought here a while back (2-3 years) and it was pointed out to me that many FMJ bullets have an open lead base, Not 'really' Full Metal. As Tiriac said, The lead core could get 'blown out' the filed 'HP Tip', leaving some or all of the copper jacket in the bore. Pull a bullet sample to verify you have a copper based bullet b4 you file away.
I then started buying SP bullets or 'all lead'.

Now I really want to try it! I don’t have any FMJs so I’ll file the base off a cup n core. … and see.

Well, I tried it, albeit with just one bullet ( hey, my 25-y-o RCBS inertial bullet puller packed it in - so what’s a guy to do?) and the bullet what it was expected to do; exit the barrel and hit what I aimed at. And the follow-up shot wasn’t impeded by “anything” left in the barrel. I found the notion that a bullet’s lead core could be forced to overcome the ogive of the gilding material to the extent that the bullet’s outer casing would remain in the barrel so improbable that it was worth the test.
