Also not great, but given that I was using a longer OAL, the direction of the error makes more sense.īullet Manufacturer’s Load Data Nosler’s load data for the 185gr JHP Fed 150 primer, Winchester brass, 1.200 OAL, 5″ 1-16 twist barrel. 811 fps predicted by Nosler, actual speed was 117fps higher, and above Noser’s maximum speed! Interpolating from the powder manufactuer’s load data gives 8.75/8.2*929=991 fps, or 63fps low. My Results My results with 185gr Nosler JHP in 45 ACP, 1.21″ OAL, mixed brass, Rem 2.1/2 primer. But even if I hadn’t - I just wasn’t impressed enough with this bullet to think it’s worth the effort of tuning for it. Mostly because I made the rookie mistake of loading up the whole box with the same OAL, instead of testing a few rounds first. I didn’t play with the OAL or tuning the gun (a usually very reliable Les Baer 1911). Recoil also occasionally felt odd, with the slide “stutter-stepping” while returning to battery. However when firing I had a few malfunctions where the flat nose of the bullet hit the bottom of the feed-ramp and stuck. Subjectively loaded rounds looked like they had a curved nose that would feed well, and hand-cycling dummy rounds was smooth - smoother with the longer OAL than shorter. I like to give a little bit of slack in case of bullet setback, etc., and I generally think 1911s feed better with longer OALs. I loaded to a 1.21″ OAL, even though all sources used a 1.2″ OAL. Cross-referencing with Western Powder’s data I think the Noselr data is just off. But when chronographing the loads using the same length/twist barrel I got significantly higher velocities. But since the bullet was marketed for accuracy in competition, I assumed that it was data tailored for bullseye shooters - who care about controllability, not terminal effect or reaching distances beyond 50 yards. I did notice that Nosler’s load data gave lower velocities than other sources for 185 grain bullets. I felt safe not starting at the minimum charge with Bullseye because the charge was safe with much heavier bullets in other manuals. So based on Nosler’s load data I picked something very close to the start with Acc#5 (my first time using it) and a middle-of-the-road charge of bullseye. I was aiming for 800fps +/- 10fps, for reliable function. Since I wasn’t going to match the USMC bullseye load, I used the easiest/cheapest components on hand: mixed brass I’d already primed. Dorman used only virgin Winchester primed cases for his long line (50 yards) loads, and once- or twice-fired WW cases with Winchester WLP (Winchester Large Pistol) primers on the short line (25 yards).”. 45 ACP … (in 1998 settling on) … New Winchester primed brass, trimmed to a consistent length the (then) relatively new Nosler 185 grain JHP 4.1 grains of Vihtavuori N310 to a loaded cartridge overall length of 1.20”. Marine Corps Pistol Team, headquartered at Quantico, VA, has undertaken extensive research and testing to develop a match-quality handload for the. I was interested in this bullet because I’d read that “…the U.S. It looks like somebody did extrapolation in a spreadsheet, instead of measuring in a lab. It was also perfectly linear with several powders, which doesn’t happen in real life. It indicated much lower velocities than I actually got. I also don’t trust Nosler’s load data for the bullet very much. ? The Nosler 185gr JHP Custom Competition Bullet (#44847) didn’t work for me because of feeding problems.
