cast bullet for 450 bushmaster

[creed]

Has anybody have any luck casting for the 450 bushmaster

[Armorer]

I guess not. Unfortunately that is what I am looking for as well.

I don't cast for the bushmaster but I would try the lyman 457122 Gould hollow point 330 grs with a good ogive so it should feed ok.

For supersonic I use my pc'd 255 grain RFN, same as 45 colt. They work great. I've only loaded a few and they shot about 4 inches at 50 yds moving at 1800 fps from a 10.5 barrel. Next batch I'll slow em down some. I've just cast and pc'd some 350 grain 457's and sized em down to 452. I want to try these subsonic thru a suppressor. Did the same with some 405's.

The 450 Bushmaster uses a 0.452 bullet

I've had some success with the MP 45 Ruger Only 320 powder coated with groups just under 2"

The NOE 452-277 shows a lot of promise... It is very well suited to the 450BM in weight and form.

I’m using the BM in an AR carbine so feeding well is always the first consideration, and this bullet works great.
After a few tests with plain-based designs that weren’t satisfactory, the NOE gas-checked bullet showed immediate improvement. Groups went from 3”+ at fifty yards to hovering 1” and less with early tests.
The casts were PCed and pushed close to full power on the first outing.
I’ll return to the project later, but although I have many options from casts I believe this one may very well be the best out of the bunch... So far.

Armorer, you do realize you responded to a question posted by someone who only ever made one post (well the same one twice in one day) 5 years ago?! And that was 3 years after he joined before making his first post. LOL

I haven't posted here for quite a while myself, but I do read the forum fairly frequently. Anyway, I'm considering picking up a 450 BM to play with and maybe hunt in the "restricted firearms zone" here in MI so this thread caught my eye. I do believe there have many discussions about cast boolits in the 450 since the OP posted his original question (and then dissapeared).

Don't get me wrong though, I don't have anyting against zombie threads, just find them ammusing. I actually had one of my threads pop back up a couple years ago TEN YEARS after the original thread had its last post, LOL.

It’s all good...
In 2015, I wouldn’t have had any input. The BM is about a year old with me now.

I guess not. Unfortunately that is what I am looking for as well.
We did a group buy here last year or maybe year before for a NOE 280g bullet. (Also cup & HP pins). Mine drop about 260/270/280 in WW.

I found good accuracy (under 2") with 5744 @ about 1700. Also a Lyman 457121 290g shoots well with same powder.

Last year I borrowed and immediately bought a Gould Express as suggested. GREAT BULLET!! Cast in AC COWW. Its designed to expand about 1450/1500 fps. I could t make it shoot at that vel but 1650 shoots about 1" and a ragged hole @ 50. Its my preferrd load for this rifle. It is a RARR.

Im not able to post pics but here is a link to another thread I have on the 450 is your intrested.

I purchased a Howa mini in 450 bushmaster to cast for. I made up a couple of dummy rounds for some flat point 45 bullets, but they would not feed. I traded the unfired rifle off. I wanted a strictly cast rifle, but it clearly wouldn't work with the mold selection i already have.

[lar45]

What about the Ruger Ranch Rifle?
I wonder if you could make up a dummy round and take it to a LGS and check for feeding before you buy.
I wonder if that Goes could have been adjusted by a good Smith to feed your blunt bullets?
I took a M1917 Enfield 30-06 and turned it in to a 30-378 Weatherby. With a good eye and a steady hand, a Dremel can work wonders...

[BK7saum]

I don't believe it could have been modified. The magazines are poly and have no adjustment. It is a center feed magazine and therefore I had hope that it would work.

If it had used metal magazines, I know I could have gotten it to feed correctly.

Mine feeds just fine...

In my son's Ranch Rifle, I use Accurate 1680 and a 290gr NOE (SC454-290-RF) sized to .452. I feeds just fine as long as you run the bolt like you mean it. Not gorilla handed but just quick. It is pc'd and it is in the 1900fps range. No lead and makes a loud "whop" when it hits the cardboard backer. It shoots in the 1 1/2" range. If it was an AR platform I would make a few dummy rounds and chamber a round and then let the 290gr be the next one in the magazine to see if it would feed.

[cwlongshot]

Americans CAN BE finiky to feed. Play with OAL and if older rotary mag many find a extra rotation of the spring helps too.

I have both and "knock wood" both work just fine. But the newer mag as seen in my video above is pretty slick.

I shoot 450g subs and they feed great. I bought the LEE 310g wfn... THAT ONE WONT FEED! ;) But the 454424 WILL! So go figure!?!?

I like rhe 457191 and the 457122 most of all. Wish I could post a pic for ya but they ahoot great @ 1800+ for the 191 and 1600 ish for the 122!!

I recently assembled a upper in 450. Still working on that one. But my subs are LASERS in it shooting into a SINGLE HOLE @ 50... But wont cycle. Most of the time will eject but never feed. Need to "massage" that load. ;) My 457122 load will not cycle either. 5744 dosent have the gass I guess...

I dont use my other RARR loads in the AR cause they could be too warm. The 550 is low pressure for the Bolt. But not for the weaker AR.

I have a 260 Barnes solid copper clocking 2350+ and shoots AT MOA in the RA... Im
Considering that UNSAFE for the AR!!

Hoping to re site the Ruger this weekwnd. I mounted a Leupold M8 3X german reticule. Much lighter then what I had mounted plus lower and quicker to the shoulder. I dont need this to be used over 125 ish. But could still hit out at 200 if needed. The reticule has a pointed post. Just not "precision". ;)

There is a link to a thread where I can post pics (post #10) couple posts above, if your interested.

The 450 Bushmaster uses a 0.452 bullet

I know the bushmaster is a. 452 and the Gould can be sized down to. 452 . I almost got one of the ruger Americans in. 450 but got a. 50-70 rolling block instead funny thing is the brass was close to the same price as the. 50

[murf205]

CW, that target with the 250gr FTX mirrors my results. The factory loads with that FTX are the most accurate in my gun.
according to Hornady, that bullet is pretty tough, as in not your average pistol construction. BUT, it sure is not a 260Barnes at 2350+fps. I had the 290gr NOE mold and it is a pretty "roundy" flat point. A boolit with a more tapered ogive would no doubt feed easier, especially if it is pc's. I have gotten by with a lot of occasional feeding problems by pc-ing. I is noticeably slicker on the ramp.

Creed, are you going to hunt with a 450Bushy and if so, what critters?
