454 casull 92 accuracy

Post by LittleBill »

What kind of accuracy are you folks seeing? Was it what you were expecting? What ranges are you shooting at? Factory ammo or handloads? If youre sending handloads what bullet weights are you loading? How hot or mild are you loading to? Cast? Jacketed?

Ive heard/read that a somewhat common issue is the frontsight dovetail being a bit too deep and affecting the bore a little, mine has this issue and so far I havent seen better than 3" +/- @ 50yds. Oddly enough 100 seems to be no worse. Now Ive nowhere near exhausted my available load combinations but Im starting to get frustrated. I dont normally fire factory ammunition because I have so much reloading supplies I just cant justify it.
45Colt though does just fine, fine enough for me anyway but I bought this gun specifically for the horsepower, I like it. I really dont want to scope it but with my eyesight I may have to. I shoot my Henry BigBoy 44mag just fine and my 16" Rossi 357 is a literal tackdriver with anything I load in it so Im wandering about the 454Casull models or more specifically I guess the 454 cartridge. So what are other owners seeing?

After having to return my first 454 because it was garbage that even they couldnt repair I got a replacement that is , besides the barrel issue, a really nice sample. The action is just superb after a bit of tuning and tinkering and Ive totally refinished and reshaped the wood. For what these things cost I really dont want to send it back to rossi AGAIN and wait another 18 weeks for a nee barrel like I had to wait for the replacement rifle.

As you can seen its a bit different from that ugly red they come with,

Or so I think. That combined with the really nice and solid action along with the horsepower available in such a small, light and very handy package makes it a quite desirable gun to me at least, I jist dont relish the thought of being short a rifle again for 3+ months. Im hoping the barrel will settle down and really start to shoot with some accuracy or I eventually stumble upon a good accurate load for it, like I did with the Henry BB I own but I am really curious as to what other owners are seeing with theirs.

I've got a 20" blued 92 in .454 Casull, and mine does a little better than the 3" at 50 yds that you're seeing.

Mine is hitting almost 2" to the left at 50 yards though. I tried drifting the rear sight, but it didn't help a whole lot. I really haven't put in much effort to fix it though, because I'm going to have the receiver drilled and tapped for a Williams receiver sight. That'll make zeroing it way easier.

As far as loads go, I've only shot my own handloads:

280 gr SWC over 11 grains Unique
280 gr SWC over 31 grains older IMR 4227
335 gr RNFP over 300MP (can't recall the charge weight)

I haven't tried a jacketed bullet load, or a commercial load yet, and I probably won't.

I would humbly like to remind that lever guns are rarely a "tac-driver" in accuracy. Having said that, it sounds like you'll need to start that frustrating process of elimination for accuracy issues. Is the muzzle's crown square and rifling crisp? Q-Tip method to look for burrs? Have you slugged the bore looking for tight or loose spots? Are your bullets of the proper size for this bore and are you shooting plain base or bevel base? You also might want to try a few gas- checked bullets. Are you getting high enough velocities to stabilize these bullets in a 1 in 30" bore? As you know, the list goes on and on.
