The bullet blew the back of the first bottle away; blew the back of the second bottle away; went through the third, fourth bottles; the jacket was caught by the fifth bottle. The lead went through all six bottles; was caught by the stack of magazines.

Thank you Ron.

I'd say the interlock failed a little, eh?

Looks like I'll be limiting the bunch I have to either paper or SML. Thanks Encore50A and Ron! As always, very informative.

I got a good deal on 150 of them and loaded a few for the Bushmaster, and planned on the rest for just trigger time. It appears that I'll be using those I loaded for trigger time too.

Didnt frag, even when the jacket separated. The core didnt shroom either. I would like to see more shot at that speed before i condemn it. Ive shot 4 deer with them in 450bm and have not had that happen. It def looks too hard for ml speeds. Agree with phalanx that it might be better suited to sml.

Photo shows why jacket and lead separated.

Petals folded so far back nothing left holding (locking) lead to jacket.

It would definitely kill a deer, that core would leave a nice hole out. Any guesses at velocity? 450 BM is nominally running 2200 -2300 at the muzzle, they probably use a harder lead core.

1700-1750

Is this the same bullet Ron tested back in 2022?

Sure looks like the same bullet.

 

[ENCORE50A]

I believe it is.........

 

[ronlaughlin]

The lead did the same thing. The jacket were different.

Would be curious what would happen if the distance was moved out to 100 yards

There is also a video on the forum with it shot out of a 458 Bushmaster but at a pretty close distance.

This bullet blew apart at 45LC carbine speeds?

Thats pretty interesting considering this video of a 2100fps-ish impact into wet phone books and deer bone.

Ron, as a new to this group member, I want to thank you for doing these tests. They are an eye opener for me. I just started in the ML game again and the choice of projectiles is overwhelming to me. It is obvious to me I cannot assume my center-fire rifle bullets will act the same way out of muzzleloader. I get the muzzle velocity is the hinge pin here. I have narrowed my choices for my muzzleloader bullets.

Am glad you are learning about bullets, however, keep in mind all I am doing is playing with guns, and having a lot of fun whilst doing so.
