The first 9.3x62 ammo ran about 2,150fps for for soft and solid 286's. The old loads worked well and Taylor noted he did not see much if any difference for the faster 1920's load running 2,340fps and that they were not needed.

I feel the 270gr. bullet is to soft for this round - even at only 2,300fps. My 9.3x62, using BLC2 powder pushes that same bullet out at 2,650fps - way to fast for the thin-skinned bullet.

The 9.2z62 was very much underloaded when it first came out, and is still underloaded today, showing ballistics from the 20's. We have much better powders today.

A member here, 9.3x57 being his handle, did a lot of bullet testing in his 9.3's, both 9.3x62 and 9.3x57. The bullets that worded the best for him, were the:
Sized down .375's to .366" - 225gr Hornady - an amazingly tough bullet that he drove at 2,550fps, yet point blank made just about as much penetration through a steer's skull + 1" boards and jugs of water, as a 300gr. .375 Swift A-Frame started at a mere 2,400fps. That's the one designed for a deer bullet for the .376H&H- for 2,900ps to 3,000fps. It is an extraordinary bullet, with 1 measured .0625" jacket - yes - 1/16" thick, (just like the .458 Speer 350gr.), A sized down 235gr. Speer .375" bullet also turned into an amazingly tough bullet in these tests.

The Privi 285gr. seemed a mite soft, not exiting the steer's skull, however do not seem to break up in bone, but expand into huge mushrooms. On the other hand, the 270gr. Speer broke a calf moose leg bone - (2" in diameter, btw) - breaking out a 2 1/2" long chunk and driving that through the rib cage into the lungs. Impacting at only 1,850fps (200yards), I expected the bullet to stay together - I was disppointed. It killed the moose, but only fragments of bullet and bone made it through the lungs.

A sized down 270gr. Hornady spire point turned in impressive penetration and killing power for Rod on very large, wild beef cattle.

The 232gr. Vulcan and 232gr. Oryx Norma bullets are or were well liked for moose in Sweden - and maybe Denmark too. At 2,450fps, they will make good 300yard big-game bullets.

The 250gr. Nosler will also be a good one and I suspect the newer Hornady 286gr. SP will also work well, giving good penetration and expansion.

I have not tried the 250 Noslers nor the 286gr. Horandy, but all the others were very accurate in my oversized groove diameter 9.3x57.

I cam across a stash of old 250gr. Barnes Old Style spitzers and have some loaded for my 9.3x62 - I think they might be interesting - will have to chronograph them.
