Tim Sundles, (Buffalo Bore Ammo owner) posted his experience using Schofield brass with 325gr LFNs and 300gr Speer JSPs on the Sixshooter Comunity website. He was getting 1,300 fps out of his 5 ½” FA97. He said “Although 45 Scholfield brass is shorter than needed, it was/is easier than trimming” 1,000 cases. When asked what he thought the pressure of this load was, he responded “Dont know, but by measuring brass and looking at fired primers, it is not alarming in any way.” I think Mark has previously mentioned that, in his opinion, this load is hotter than he was willing use in his guns.
Using .45 Colt brass, I’ve loaded the Montana Bullet Works RCBS 300gr SWCGC (actual weight 315gr) to 1,130 fps in my 4 ¼” FA97 (this load is a handful). When crimped in the crimp grove, this bullet is right at the face of the cylinder. Due to the recoil, and possible bullet jump, I crimp this bullet over the front drive band. This load shoots to the same POI as the RCBS 270gr SAA at 915 fps, which is my standard load in the M97, (also crimped over the front drive band).
You can also load the Speer 300gr JSP (using the crimp grove closest to the nose). Buffalo Bore offers just such a load for the FA97:
Item 3D: 300 gr. Speer J.F.N. (1200 fps / M.E. 959 ft. lbs.) (Loaded to shorter length 1.585 inch specifically for Freedom
Arms Model 97 .45 Colt - Big game up to 800 lbs.)
For all practical purposes, the 270gr SAA at 900 fps should be adequate for about 99% of any situation you may encounter.
I guess what I’m getting at is that you can work around the short cyl in the . 45 Colt M97 if you really need to.
These are very compact, powerful handguns and there aren’t many situations where I would feel undergunned with one in .45 Colt.
