Went to the range yesterday to try some reloads I assembled on Friday (used my last vacation day from work) for my 45 auto's.
Load #1 was a 230 gr. Lead RN @ .452" (Falcon Bullet Co.); 4.3 grs. Bullseye and Rem LPP. Loaded on range brass.
Load #2 was a 200 gr. Lead SWC @ .452" (Falcon Bullet Co.); 4.3 grs. Bullseye and Rem LPP.
Besides the M&P 45, I also took my Ruger SR1911. All shooting at 5 yds off hand. The M&P 45 was freshly cleaned the night before; the Ruger still dirty from previous range visit. It was odd that both firearms wouldn't feed the first round from a fully loaded mag. With the Ruger, it was one of the 200 gr. SWC; with the M&P, it was the 230 gr. RN. I shot 5 rounds of each load through both pistols for sighting purposes. Then loaded full mags afterwards.
The first round of 200 gr. SWC into the Ruger jammed half-way into the chamber. When I cleared the round, the brass had a small area that had been pushed back, creating a "nick" in the brass. After re-inserting the mag, everything else shot/fed as usual (25 of the 26 rounds) from my Ruger 8 round mags. The results were 25 rounds into a group 1 1/2" x 2 1/4"-all shots within the 3" black of a standard 50' target. The range provides targets at no charge.
With the Ruger and 230 gr. RN load, the first 5 shots resulted in a one hole grouping of 1/2", I pulled this target to save! The remaining 36 rounds fired into a group 1 1/2" x 2", I did have 2 flyers that opened the group to 1 1/2" x 2 1/2", these were called flyers and my fault, not the guns' LOL
The M&P 45 had a jam on the first round of 230 gr. RN, which I found odd; since it resembles a factory ball load. Same as the Ruger-when cleared, the resulting round had a small "nick" in the case. And once again, everything ran fine afterwards. With this load, (39 rounds) the main group was 2 1/4" x 2 1/2", with one called flyer which opened the group to 2 1/4" x 3". All shots cleaned the 3" bull on the target, with exception being the one flyer.
The 200 gr. SWC load fed flawlessly from start to finish. 24 rounds printed a group of 2" x 2 1/4" with no flyers. All centered in the black of the target.
My goal is to keep all my shots, from 5-10 yards in 3" groups. I am not a target shooter, but accuracy is important to me. And I don't mean 5 shots, 3" @ 5 yrds, ALL shots in 3" at 5 yds (25, 30, 50 rounds). IMO, if you can keep 50 rounds in a 3" group, then you are being consistent, and so is the gun/ammunition.
