The 454 Casull best information ever posted about it

[CowboyTutt]

No problem ol' friend. Its a custom bullet made by McPherson and my friend has the molds. I need to contact his mold maker and get a set made that a bullet maker can use to cast me more bullets and make them available for everyone. The bullet is modeled after the RCBS Silhouette 45-70 bullet and weighs 410 grain with wheel weights. McPherson changed the diameter and design slightly. Eight grains of Longshot out of Mic's FA 83 with a 5.5 inch barrel was 864 fps average of a 10 shot string. Eight point five grains was 911 fps average out of the same gun. We think 11 grains yielded about 1000 fps but we seem to have misplaced the original data on that. All loads with a CCI 450 small rifle magnum primer. The FA had higher velocities due to the tighter tolerances of the gun compared to the Ruger and my Raging Bull and 8.5 inch barrel. I agree, for hunting purposes at close range, you don't need anything more. The faster velocities and lighter bullets for the Casull offer a flatter trajectory, thus the cartridges use in silouetter shooting as you know or longer range hunting in case you are channeling Jim Taylor.

Hah. Not into channeling

Thanks Cowboy,

Just curious about the loads. They sound hot but it seems they are in the range of the 44 hunting loads. Or the other way around. I didn't push my loads for velocity, but was after repeatable accuracy. These were 320 Gr plane base TC cast over 21.5 Gr of 296. This was in '88 when I started shooting cast. My later loads were 21 Gr. I have no idea what the velocity from the 10" SBH was... once I got to 21 every single load under the 320 was the same for years. until I ran out of them. LOL Never found a reason to race 'em.

I have an old note about a 300 Gr Sierra bullet that was 19 Gr of 296. Daughter took a caribou with that combination. Again, no clue about velocity but the caribou didn't object. My note-taking was not stellar.

I think I mostly found loads in the RCBS manual and started below their start load.

Just fun stuff to review now. My experimenting days are over I think. Thanks again for the info.

Just resurrecting this thread Tutt as it was such a great read. It was interesting to hear NKJ mention that the first three years of Rossi 454's had the early production run issues and they sorted a lot of it out by 2005.

I was trying to find another thread where testing was done in the 80's I think, folks maybe from the same group... trying very hard to get 454 casull to work in a marlin? Does that ring a bell with anyone? Also was another thread on people testing casull pressures in regular rossi 45 colts and it did okay for a couple hundred rounds but was stretching the receiver. Id like to compile all these anecdotes and experiences with the 454 for my own interest

Yep - there were many such discussions on this forum along that line. I don't remember any of the thread titles, nor necessarily the participants, so would hve to just search the forum for 'Marlin' and 'Casull' and see what turns up...

Here's ONE of the threads - viewtopic.php?t=27722

'Buck Elliott' I think was one of the ones who knew the guys doing the actual testing and development...?
