Thread: 450 bm

Hi HNK 770 ; I see u in Papamoa. Broncos Outdoors has Red Dot , which seems to be a really nice powder to use for sub loads in my 45/70. There is an American article” Leveraction sub load data” off the top of my head which has a lot of data on sub loads for 45/70 with lots different powders . I know it’s not the same caliber as the 450 Bushmaster but there might be new info on that site ( I can find exact name to google once I get home) . For Red dot I’ve ended up with 12.5 gr with Hornady jacketed Sub x 410 gr & 11.5 gr with hard cast. You probably know ; start loads slightly super sonic with NO Suppresser on & carefully work down. Keep checking the target paper to make sure the projectile is stabilizing & punching thru with a nice round hole. If I’m not mistaken I’m not far away from you & can lend u a chrony if u need

Hi there , good to see someone loading for the 450 bushmaster I brought one a few months back a have enjoyed loading for it ,just my own cast bullets so far have had trouble loading them but happy with them accuracy .

Hi Gur1 ; weren’t you running a Begara & a Henry both in 45/70? If so ; out of curiosity , what made u change to the 450 bushmaster?

Was interested in 450 before the 45/70 the guy I brought my Lyman Gould mould off was running it in his 450 but it was easier to get started casting and loading if I just went with a 45/70 so I got the bergara and loved it but when I saw the little Henry for sale and with the trigger job that needed doing had been done I could not resist and it’s my favourite rifle in the box , I think , but on a few hunts lately I have or would have liked a 2 nd shot a bit quicker, well that was my excuse so I brought a Howa mini in 450 . Will move the bergara on sometime .

I was keen on the 1/16 twist as well for my Lyman Gould bullet moving along nice and slow .

Had read good things about the Gould bullet so when I saw one on trade me I got it , when it turned up the misses asked which rifle it was for I just smiled, and then COVID arrived in the country and it took awhile to get a 45/70 .

So did u have to buy 2 sizing dies for your cast bullets? .458 for the 45/70 & .453 for the 450 bushmaster? How do the cast look after the smaller sizing die?

Morning, a 452 sizing die come with the Lyman mould and I have never sized for my 45/70 , just powder coated and loaded and have had good results so far , for my 450 I have sized after powder coating and they seem to come out better then doing it before coating .
