They start with stringing one way, go through the sweet spot where the groups tighten up, then string the other way. It is more pronounced with rifles, but it can and does happen with handguns also. Some guns shooting cast boolits exhibit a change in the shape of groups as you move on up the charge table. Stringing (as opposed to patterns like a shotgun ) is generally a sign of a good shooter and a load that needs a bit of tweaking up or down. Factory ammo has more variation than that. That small a variance in OAL (or COL if you prefer) isn't the cause. (Arms are locked straight so the "wobble" happens vertically.) It has disappeared when firing hotter self defense or hunting loads. The same thing has happened to me with an isosceles stance and light loads. Notes: ? Stronger recoil than Trail Boss, but noticeably less than standard 230 grain loads.First off, I would ask if it is the gun or the shooter? I am assuming this already occurred to you and you have tried resting it and evaluated your stance, grip, etc., to eliminate the shooter from the equation as much as possible. I also crimped aggressively, but the COL was the true fix. Seating deeper to (1.240″ COL) fixed the problem. This shot fine in the one and only 1911 I tested, but after acquiring a chamber-gauge, I realized the rounds did not chamber in it. I initially had a longer OAL of 1.255″, to be conservative about pressure. Their load data shows 1.225″ COL for 200 GR RN Polycoat Bullet. Weight was pretty consistent, 200 – 203 grains. The coating did flake more than I’d like in shipping, leaving spots of exposed lead. Notes: ? Unfortunately the pink bullet seems to be discontinued.

But it’s important to acknowledge that I do not know for certain what the cause was here. Before the late 2020 primer shortages I was trying to transition all my 45 Colt loads to WLP primers for this reason. This happens to me sometimes with strong hammer springs (like in an M83 or T/C Contender) and Rem 2.1/2 primers. No shot was noticeably louder or had more recoil or velocity. I do not believe it to be a high pressure sign. Unfortunately I had a pierced primer so I stopped shooting. Only 4 shots registered on the LabRadar, 777fps average, with an ES of 33 = 794 – 761. Point of impact was low at 50 yards compared to 250 grain slugs. Powder: Clays 4.6gr (per Modern Reloading 2nd edition by Richard Lee, page 581, start at 4.6 gr for 777 max 5.9gr 931fps and 13100 CUP 1.6″ OAL)īullet: ACME (.452)200gr RNFP bullet with “NLG” coatingįired at Los Altos Rod and Gun Club in a 5.1/2″ Freedom Arms Model 97. While obviously inexpensive it was much nicer than I expected! It would be very much at home as an ammo box in any Cowboy kit. When I ordered from Grafs the bullets came in a wooden box. ACME says they are cast with 92-6-2 alloy then coated and baked three times with Hi-Tek, prior to sizing.

The ACME Bullet Company line of “Lipstick” bullets are a lovely bright red. Some soot on the outside of the cases makes me think I was getting this speed at low pressure. Notes: Recoil was every bit as bad as loading up another powder to +P pressures to get the same speed. I did: “ Bullseye #2” 200 grain coated SWC from MBC, (.452″ diameter, 0.644″ long, Brinell 12 “for bullseye”), Rem 2.12 primer, #41.5 (3BR pistol measure) = 7.4-7.5gr CFE Pistol, 1.255″ OAL, mixed brass.

Yes, the start load really is nearly 1050 feet per second, and it was faster than every other maximum load with that bullet! Hodgdon data: Winchester case, Fed 150 LP primer, 5″ 1:16 twist barrel. Handloader magazine and Hodgdon have published some impressively fast loads using CFE Pistol.
