OK-= here's a few sectioned bullets. The right hand 3 were expanded slightly to better show the thickness of jacket with the lead still in them.
: right to left:

1/. - 220gr. Hornady -note the fairly heavy jacket. I've taken two moose with this one - a big cow - 1 1/2 steps after impact & dropped - bullet went through onside leg, double lunged and under hide off side - perfectly expanded to jsut above crimp groove - initial velocity 1,940fps - range 95 yards. 2nd was a bull moose, same load @ 75 yards, bullet entered at 4th rib back, paunch, liver and right lung -bullet perfectly expanded in right shoulder.
2/. - 235gr. Speer - note is a bit hard for 2,00fps, but should be great for the 9.5x57 @ about 2,400fps+
3/. - 225 hornady 9.3x57 noted - he's shot 2 deer with it along with fairly extensive penetrative testing on media - good heavy jacket and over 2 feet of penetration on length-wise shots hitting behind last rib. should be a goood bullet for the 9.5x57 at 2,550fps to 2,600fps.
4/. - old style 270gr. RN Elmer Keith spoke well of in comparrison to the 300gr. RN.
5/. - 300gr. RN Interlock - it appears this bullet's jacket should allow more controlled expansion than it gives - interesting. I didn't section a 300gr. Interbond- that should be a good bullet for higher speed .375's.
6/. - 270gr. Spire point - excellent bullet, deep penetration at 2,550fps - would be a good 'heavy' expanding bullet for the 9.5x57 @ 2,300fps+
7/. - 300gr. Barnes .049" jacket spire point - great bullet for full power loads in H&H. Accurate
