I have not gone any further. Been too busy with food plottin' this summer. I will say tho, Im not sure 450 BM plus this hammer will ever be a 400 yd rifle on paper, I don't see how this bullet, with a bc around .200 g1 could be propelled fast enough from this cartridge. I did a lot of looking around before buying, if you want 400 yards, check out 444 marlin, cva single shot, and cutting edge bullets. I believe that will get you there.
45 Raptor will get you there. I'm at 2600 fps with 240 Bear creek tipped bullets(BC .265). That's not top speed but it's my accuracy load.
Wow!! That's smoking!! I'm using H110 and will have to be up that high also. I was basing it off a Barnes 250gr load so was staring at 36.5 grains but you're thinking I have to be a lot higher for this lighter bullet?
Hammers for my Gunsite Scout that worked just fine in my rifle. My son decided to try a few of my ammunition in his AR. Well the first round fired just fine, the second round was a squibb round. Essentially when the bolt came forward it came forward so hard that when the blot closed, the bullet pulled out only to stop when it hit the rifling. From there the only thing that fired was the primer. His AR is a custom "everything" including a heavy buffer spring. I am using a Lee Factory Crimp die, only for his AR I am using a full turn on the crimp, haven't had a chance to try them yet.

I've been trying to find a cartridge that would work in my short-action, Ruger 77 tang safety for quite some time now. I just sold a Ruger, Gunsite Scout in 450 Bushmaster because I did not like the box magazine or...its release. This past season I was sitting in a ground blind when I looked down only to find the magazine sitting in my lap. That's not a good plan!! I was seriously looking at the Christensen Arms Ridgeline in 450 Bushmaster, only to find that it too had a box magazine. While doing some research I found the 45 Raptor to be a viable candidate for this conversion. The Ruger 77 short action is in 22-250, so right bolt face, and essentially the dimensions on the 45 Raptor are quite similar to the .308 Winchester another plus for the conversion. So...now I started looking for a barrel for a bolt rifle, not so easy as one would think. While doing more research I found a barrel company called "X-Caliber" barrel company. And...they make a bolt rifle barrel that usually costs $369 on sale for $295, contoured; button rifling, stressed relieved. So...hopefully there will be a 45 Raptor sitting with me in my ground blind next bear season. Thank you for posting this information on the ballistics.
Mine carries a 24" barrel which helps. I can push it faster but for the best accuracy, thats where I'm at. It's 200-250 fps faster than the 450BM easily with same length barrel. It's a higher pressure cartridge than the 450BM allowing for the extra performance.
