I've got two very different applications:

1) A 45-120 built off an H&R Handi Rifle. At 40k PSI pressures this thing is a handful. I'm looking for 300-405gr bullets that are the most fragile to do some deer slaying this fall. 405gr Remingtons at 2550fps have been pretty good in the past.

2) 458 Socom SBR. This is going to be subsonic only, I'm looking for something that can expand at sub 1000fps velocities.

Thanks for your advice!

Plated. Intended for target shooting.

Tyler, I remember you building the 45-120. Consider the Barnes TTSX 300-grain monometal designed for the .458 Socom. The guys are getting very good expansion at Socom velocities, so you should expect the same or better at the higher velocities your Handi Rifle is capable of.
As to subsonic heavies, this guy's Youtube is crazy.

Tyler, I like your shooting project.
The 45-120 is perfect.

Sorry I don't know much about really soft bullets but I think you have a good idea.

Ed Hubel and I converted a Handi Rifle to 577NE (24ga Frome Hell.) Later I made a 50-110 Handi Rifle. Both were done with the "barrel stub" process. Both barrels have killed several cape buffalo. Seven in all. Very satisfying rifle to hunt with.

suggestion: You can make a spare/switch for-end that is weighted with brass or leads shot and epoxy to tame the recoil for heavy load development. My 577 NE weighed 13 lbs. at one point.

For the Handi Rifle, Ed likes N550 and N540 powder for its ideal pressure curve.

Congratulations on graduating and starting
MK Machining.

Best of luck to you.

PS, I'll bet that Bill/Oregon has suggested a good bullet for you. Never use them but it sounds right.

ether the 300gr nosler ballistic tip's are pretty soft shooting out of my 450 Nitro

I've used the 250 & 325 in a Socom, 458WM, & 45-110--2/7/8" Sharps. Great bullets

Tyler, Sorry to hijack your thread.

Would these bullets blow up on varmints from the 458 Win Mag.?

Soft jacket bullet in 405 weight would be the 405 Remington Corlockt. Should be cheap too.

From THE.458 WIN THREAD FROM HEAVEN:



You want a fragile, jacketed .458-caliber bullet?
The Sierra Pro-Hunter 300-gr FNHP is it!
At 2800 fps they vaporize as soon as they leave the confinement of the rifling.
That happens with about 75 grains of AA-1680 in the SAAMI .458 WIN.
Sierra recommends no faster than 2500 fps.
Even that might be too fast.
The exposed lead of the hollow point is so soft that I can expand it at very low impact velocity with my thumbnail!
The base of the bullet is about as thin as a gas check.
I know from finding the base of one on the ground in front of a busted ProChrono.

The Barnes 300-grain TTSX was designed for the .458 SOCOM.
Shoot it at high MV for best results.
At subsonic? Dunno.
Might be like a wobbly football and work by tumbling on impact.

Shooting the Sierra FNHP subsonic in a .458 SOCOM could be fun, about like using a handgun bullet in the .450 Bushmaster.

And:
The previous edition, Nosler Reloading Guide 8 has loads for the .458 SOCOM and the Nosler 300-grain Ballistic Tip,
from a 16" barrel length (1:14" twist),
MV's of 1500 to 1950 fps.

Surely for 300-grainer at 2800-2900 fps, a Nosler partition would be less likely to explode at the muzzle.



Not sure about the Nosler Ballistic tip, despite their generic claim for velocity window:
Minimum: 1800 fps
Maximum 3200 fps
I'd say keep it down to 2500 fps MV also.



I have not tried these yet,
do not know if Nosler still makes them.

But whatever shoots most accurately, even if it does not expand at all, a .458 caliber bullet is pre-expanded, for expert use on head and neck shots.

I agree with RIP on the Sierra Pro-Hunters and have gone so far as to throwing them in the lathe and opening up the hollow point to ensure lively results on impact. Weight was only reduced by 10 gr. Can't remember the bit size.

Tyler,
On the 45-120 Nitro - i have found that the rem 405 to be soft, cheap, and ACCURATE .. when developing this, Rocky made 45/120 nitro enfield .. we used it to get max vels and then target down for my double rifle...

we used everything from light 250gr through 700+gr cast -- and since we had over 3,000 405s, that didn't hurt things

there was a user here that either made or used some bullet swaging dies to point remington 405s to 400gr spitzers ... i wish i had that setup

It looks like the Berry's bullets and Sierra Pro Hunters might not take the velocity? I do want them to blow up...but not just out of the barrel

Another vote for the Barnes 300 grain TTSX, I've used them in my Socom on several deer and a number of hogs. Never tried them at higher velocities, so no feedback on that.

Remington 405gr FN recovered from Bull Moose. 1600 fps impact speed. Angle shot. Thin jacketed but didn't fragment. Expanded real wide which limited penetration.

Hornady 300gr HP went clear through a Bighorn Sheep at about 2400 fps impact speed. Also an angle shot. Surprisingly tough bullet!

Maybe what you're after is a Glaser Safety Slug -
