Bullet weight+velocity sometimes equals less penatration?

[my_old_glock]

Has anyone tried the HAP bullet? Should be less expanding so no need to reduce the velocity.

I think the HAP is suppose to be a low cost training alternative to their hollow-point bullets. The HAP bullets have the same basic shape and weight as their HP counterpart.

The HAP is short for Hornady Action Pistol. It is intended for IPSC/Steel Plate and other forms of competition where expansion is only relevent in terms of diminishing the damage to the steels that a FMJ might cause.

I see.

 In the narrow issue , the OP is basically correct about penetration per se.  In rule of thumb , expansion is inversely porportional to penetration.

The question of what is "better" for hunting has a lot more variables. The game, shot placement , what shots/ angles you are willing to take, and frankly the philosophical preferences of the hunter. Examples : Small-ish whitetail , only taking unobstructed heart/ lung shots , only moderate penetration needed , and big expansion is a plus. Aiming for offside shoulder on an elk, or a large boar lots of penetration is needed. Controled expansion vs hard cast is Ford vs Chevy raised to a near religous intensity.

i think your basic premise is correct. i also think that in that lesser penetration the bullet is transferring more and all of its considerable energy to the target.

I don't know if anyone has seen the hunting show with Razor Dobbs but he hunts with his Dan Wesson 10mm 9 times out of 10. He has taken axis deer, mule deer and whitetail deer and he uses the same bullet and claims to love the performance of it. It's the 155gr Barnes TAC-XP at a claimed 1500fps.

I haven't seen that show, but I use these bullets, out of necessity in CA. Although I would use a lead-based bullet given the choice, they are effective. The velocities I load are 1500 FPS (5.2" Glock), 1590 (6.5" 10mm revolver), and 1950 (6.5" .38-40 revolver).

This is not new to the argument old guys know that a high velocity round may very well explode on impact and not penetrate at all. Particularly if it hits something hard like bone.

Perhaps, with traditional lead-based bullets. We're talking monolithic, here. The Barnes bullets hold together quite well, all things considered. They are better when overdriven, in my experience. I don't like that I HAVE to use them, but they do the job, and do it well. Hard obstacles, such as bone, they really shine.

[sqlbullet]

They do a fine job.  I would like to see us moving to copper jacketed depleted uranium slugs in lead free zones.

I know one thing the 105 grain DRT Dynamic Research Technology bullets are leaving my LW long slide at 1800 FPS and the do not penetrate extremely deep but the game drops at the shot considerable damage to the boiler room.

The Shadow knows Erich. This individual has it right when he postulates:

When it comes to handgun rounds;

a) Shot placement is king,

b) penetration is queen,

e) everything else is "angels dancing on the heads of pins".

Pigs and bears need heavy bullets to penetrate gristle plates and bone.
