Accuracy Expectations with .357 Big Boy Steel
Posted: Mon Aug 22, 2022 11:03 am
New member making my first post here. I checked the forums and didn't find anything specific to my question, so here goes.
Having always wanted to own a lever rifle in .357, I was happy to find one, a Henry, at my local shop. To my surprise, it already had a Skinner peep mounted on it. A week later, I was the proud owner of a Henry Big Boy Steel .357 with a 20 inch barrel and a loading gate. The rifle looks good, feels good, and shoulders quickly. As a Service Rifle competitor, I really like the sight picture with the peep too.
Took the rifle out in my yard and spent a little time shooting some .38 HBWC ammo I load for Bullseye Pistol. First observation was that the Skinner peep could not be adjusted low enough for impacts to match point-of-aim at 25 yards. Everything hit way high. Figured it might be the ammo, as lighter loads frequently hit higher in revolvers, but that's all I shot that first day. It grouped around 3 inches though, which was not what I expected, I felt it should do better. Granted, 2.7 grains of Bullseye is a light load, but it's accurate as heck in everything else I own. Now my choice was whether to buy the higher front sight from Skinner, or go with a base for an optic sight. I decided the optic sight was the best choice.
So I ordered the Picatinny style base for my rifle, and mounted a Bushnell TRS-25 dot sight. Picked that one because it has the smallest dot, supposedly 2 MOA. I really don't like that the cheek weld I had with the peep was now more of a chin weld since the sight sits much higher, but it's the hits that count. I also loaded up some loads with .357 brass and used both 158 round nose lead and semi wadcutter bullets that I had for Distinguished Revolver matches. Only took a couple shots to get sighted in, and the rifle cycled these cartridges much better than the wadcutters, but again, groups were around 3 inches at 25 yards. Not happy with that at all.
Finally, I decided to try a scope, and bought a Bushnell Prime 1-4 x 32 for this specific rifle. Mounted it in a set of weaver rings, and now the sight line is even higher, but the sight picture is bright and clear. I also bought a box of Fiocchi .357 factory loads, with 142 grain FMJTC bullets, to make sure that the lead bullets weren't the issue. Unfortunately, I'm still not getting acceptable results, with groups still running at 3 inches at 25 yards, and well over 6 inches at 50.
I've checked the mounts for the scope and everything is tight. The crown on the rifle looks and feels good, and running a Q-tip on the crown is not showing any rough spots. There is a little play in the forearm wood, maybe a sixteenth at the rear near the receiver, but I've heard that is desirable for these rifles. I don't expect this rifle to shoot MOA, but now I'm looking at over 10 MOA, and that is with three different sighting configurations, and that's not what I expected at all. For reference, all shooting for groups is done using either a Caldwell Stinger, or off a front rest, owl ear bag, and bunny ear bag rear rest. The rifle is rock-solid using either.
So reading through all the threads here, I see phrases like "shoots sweet", or "nice groups", and similar non-quantitative comments, but little with actual group sizes. I've seen a few claim groups of about 3 inches at 100 yards, which I'd be elated to achieve, but I don't really know if that is realistic or not. I'm not a new shooter, and know that I have good and bad days, but I can pick up the 1022 I built back in the early 90s and shoot 10 shots inside a 1 inch paster at 50 yards without issue, and can still hit half the rams at 100 meters standing.
For those that do actual measurements, what group sizes do you get at specific distances with these rifles?
And apologies for the long-winded explanation for how I got to where I'm at.
