    Cool

    I had great success with the Lee 255RF in both my Winchester M95 Trapper and my short-barreled Ruger BH. Too, the 300 LFN bullet gave a higher-power load in both, although feeding could be a challenging in the M94.

    Another vote for the RCBS 45-270-SAA here. Your Rossi 92 should be able to handle "Ruger" level loads just fine, but it's interesting that you found leading near the muzzle with your 14 gr. Blue Dot load, and dropping the load some fixed that. I wonder if the specific lube you had on those bullets had deteriorated since the time you cast them back in the 1970s? I'm assuming you lubed them back then, but if you lubed them recently, then maybe try a different lube?

    Maybe there's really nothing to "fix" though--the load you settled on sounds like it has plenty of penetration at 75 yards and is accurate.

    When I lived in Alaska I loaded this bullet in my 94 Winchester .45 Colt, and used the same bullet in my Ruger Blackhawk.

    It is the Lee 457 340. This bullet was used in developing some of the early heavy .45 Colt loads for the Blackhawk. It shot well in my Winchester.

    Larry pressure tested this load for me to use in my Ruger Blackhawk and H&R Handi Rifle.

    I've been very satisfied.

    Slightly exceeds SAAMI MAP for .45 Colt, at 17,400 psi, but well within design limits for modern Colt Clones, Colt New Service M1909 and similar sturdy pre-WW2 smokeless frames.

    No issues for Ruger New Model Vaquero, etc.

    960 fps for 295-grain bullet with 7.5 grains of Alliant Bullseye from 10-inch Contender.

    Well I concentrated on deer hunting and took three but only one with the cast load from my Rossi. A high shoulder hit dropped a 100 pound doe in her tracks and exited leaving a 1 inch hole. The bullet went through both shoulder blades on the thin end, the spine and out the other side. Pretty clean wound channel a bit over 1 inch in diameter that really didn't change much going through the spine. I also kept this rifle handy in the cab of the truck but no targets of opportunity came around. However hog hunting in earnest begins again.

    The lube which I can't remember who made is red and I don't like it much could be the problem. But still I think I can get away with shooting them up.

    Did you size the bullet down or leave it as cast?

    As-cast and unsized, 1:30 tin-lead from Roto Metals, Lee Liquid Alox.

Would like a bullet in the 290 to 320 grain weight range. Prefer a flat based design.
    A couple problems with your Rossi M92; first is the 1:30" twist as already mentioned. I had a Rossi M92 rifle (24" barrel) and even with the longer barrel found the heavier Lee 300 gr bullet did not stabilize adequately for best accuracy across the ranges I intended to use the rifle, especially with SAAMI spec loads safe in my Uberti SAAs. Pushing it harder to top end loads it shot reasonably well, at least to 100 yards.

    Pushing it at top end Ruger loads could lead potentially to the 2nd problem; the magazine tube was only held in with the barrel band/screw. Under the heavier recoil of several Ruger level loads the magazine tube would walk out and failure to feed would result necessitating disassembly to clear. Rossi solved this problem in heavier recoiling M92s [the 454 Casulls and 44 Magnums(?)] by threading the tube into the receiver. Apparently some don't have this problem but I did. You might check to see if the tube on yours is threaded.

    Honestly I think you'll find top end loads such as mentioned by Outpost and tested by me or one of Unique under your 255 lee bullet at 1050 - 1150 fps will shoot quite well and give all the terminal ballistics needed for the pigs.

    It is always something. I feel 270 grains is heavy enough and the speed I am getting with 13.0 grains of Blue Dot seems fast enough. I still have at least three hundred of the 270 gr. bullets so I am good for the summer.
