Not helping after the week I am having, was going to do a job in Samoa last week then leaving last friday week ago then last Sunday then first thing monday and now cancelled. And the kicker was the only info I was given was exactly that, no Idea what I was actually going to do or what i needed to take.
Working for a company employing a heap of Seagull Managers sux

Tipped this guy up today with the 450 bushmaster. Was at an honest 100 so a good stretch for a sub gun.
He was dead before he new what had happened, bullet performance was good. The loudest noise was the thump as the pill hit home.

Boooya ! Right in the boiler room. Did not do much to the projectile. How far in did it penetrate ?

It had gone clean through the middle of the lungs and was resting against the far side of the skin.

Can't ask for better than that. Expended all it's energy in the animal.

Just did some expansion testing with the 450 BM into a 44 gallon nearly full of water, it certainly makes the drum jump.

I tested the Hornady 300 XTP, 225 & 250 FTX & the Sierra 230 JHP.

They all hit the bottom of the drum & dented it to a greater or lesser degree

They were all going around 950fps.

You can see that the 225 FTX pistol projectile really flew to bits

I decided to try the 250 FTXs that I have pulled from the Factory Hornady 450 Bushmaster rounds.

I'm glad I did as it really showed the typical lack of expansion I have seen from conventional jacketed rifle projectiles in the past at subsonic speeds.

You could literally load them & fire them again

Yep, xtp was all i could get to expand in 30cal. Unfortunately Bugger all pistol projectiles available in 30cal.

Whats the range on these pistola subs 10 m?

can these go on a standard ar15? e.g is the bolt the same as 223? just barrel different?

It is a 308 bolt face, it was made for the AR15 with a bigger bolt face.

It uses small rifle primers & is basically a 284 win cut off at the shoulder.

Can't really make the brass from 284 though without reaming as it is too thick

I have been doing a bit more testing/development with the 450 Bushmaster, while I still have the Tikka & I'm waiting for my Kimber to be finished.

Here is a target showing the drop & groups at 50yards between the 250 Factory load & subs, including initial velocity testing of the Lehigh 170.



Here is another I shot today testing the 170 Lehighs at subsonic speeds.
Some times funny thing happen Subsonic with some loads also sometimes the case doesn't always seal that well, letting a bit of gas past the case & down the bolt

Less of an issue if you bring the speed up a little.



I put some 170 Lehighs subsonic loads & some factory 250 ftx loads into the 44 gallon water drum, the 250s really made things jump around



They both opened up well, it is a pretty hard test on the projectiles, but its great to see what another 1100 fps did to Factory 250 FTXs.

I loaded up some of the 250 Ftxs today, the factory velocity is around 2025, they are loaded for the AR15s so probably not going that hard.

I managed to get put 200 fps on that speed with the 12" barrel happily giving 2200-2225fps, the projectiles I found in the mound were well expanded

So they look like they will be a great supersonic load.

This makes the 450 Bushmaster the ultimate bush rifle, short & light with tons of grunt, either super or subsonic
