Joedirt199 Posted February 9, 2020 Share Posted February 9, 2020 (edited) So tested some Summers coated LRN trying for a nice light recoiling load for some falling plate steel matches. Used 160 RN, 145 RN, and 135 RN that started as .357 sized down to .356 with a Lee Bullet sizing die. Groups were not great as I had a 20-30 mph wind but the temp was better for a mid February day at 55* so had to get out and get some numbers. All of these shot out of my CZ P09 with RMR. Was shooting for 130 PF. All hand weighed charges with federal brass and winchester primers. 5 shot strings shot at 20 yards off a bench rest. I have used WSF but have seen its temp sensitivity and I shoot matches all year so don't want to have to change the load for different seasons. Did have a couple of tumbling 145s so may just leave these as .357 and try some again. Some of these were from other people's loads and some are for a baseline as I didn't have much to go on. Any help would be appreciated 160 LRN Win 244 2.9 gr AVG 808 ES 15 SD 7 OAL 1.12" 145 LRN Win 244 3.4 gr AVG 923 ES 20 SD 8 OAL 1.11" 135 LRN Win 244 3.5 gr AVG 973 ES 27 SD 11 OAL 1.10" 160 LRN Power Pistol 3.8 AVG 862 ES 25 SD 9 145 LRN Power Pistol 3.9 AVG 878 ES 38 SD 16 135 LRN Power Pistol 4.1 AVG 925 ES 34 SD 14 160 LRN Sport Pistol 3.1 AVG 837 ES 26 SD 10 145 LRN Sport Pistol 3.4 AVG 929 ES 12 SD 5 135 LRN Sport Pistol 3.5 AVG 985 ES 17 SD 7 160 LRN HP-38 3.0 AVG 810 ES 19 SD 8 145 LRN HP-38 3.2 AVG 867 ES 15 SD 6 135 LRN HP-38 3.5 AVG 945 ES 43 SD 18 160 LRN Tightgroup 2.7 AVG 796 ES 22 SD 9 145 LRN Tightgroup 3.1 AVG 909 ES 13 SD 5 135 LRN Tightgroup 3.5 AVG 1009 ES 29 SD 12 Edited February 9, 2020 by Joedirt199 Link to comment Share on other sites More sharing options...
igolfat8 Posted February 10, 2020 Share Posted February 10, 2020 I shoot coated 95 grain cast boolits for falling steel. I like lighter and faster boolits. Slaps steel down with more authority than slower heavier bullets. Link to comment Share on other sites More sharing options...
Joedirt199 Posted February 10, 2020 Author Share Posted February 10, 2020 I guess it is the same concept either way, slow and heavy or light and fast. Just all boils down to recoil impulse you like. The 135s felt good and I already know my p09 likes 124s. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted February 10, 2020 Share Posted February 10, 2020 14 hours ago, Joedirt199 said: Was shooting for 130 PF. Since you're experimenting, you might try running that up to PF 135 - 140. Should knock the steel down better than PF 130, and I would guess you will not feel the difference from PF 130.

Joedirt199 Posted February 10, 2020 Author Share Posted February 10, 2020 Will give it a try since the match is not till June. Gives me some time to tinker. Link to comment Share on other sites More sharing options...
thormx538 Posted February 11, 2020 Share Posted February 11, 2020 I tested some Bayou 160s at 1.150" with Sport Pistol. Charge 2.7 2.8 2.9 3.0 3.1 Avg 814.8 842.75 853 865 878 PF 129.6 134 135.6 137.5 139.7 SD 7.7 10.04 15.39 7.07 7.4 ES 19 23 30 10 19 1.150" was about as long as I could load them and get plunk/spin (320 Legion). We didn't do any accuracy testing off a rest but they all seemed to group the same off hand with no tumbling. Only fired 5 rounds over the chrono in each case and not every one produced a reading (only 2 did on 3.0) so take the SD numbers with a grain of salt. But 2.8 is probably what I'll load more of.

LaPoint Posted February 12, 2020 Share Posted February 12, 2020 (edited) I fired 18 rounds across my chronograph yesterday with 160 grn Bayou and 2.8 grn of Sport pistol. I loaded them to 1.165" OAL in Win. cases with Fed GM primers. The average velocity was 804 ft/sec. Extreme spread was 30 ft/sec. SD was 7 ft/sec. Average Power Factor (PF) was 128. Low PF was 126. High PF was 130. It was 25F outside and the Barometric Pressure was 30.03" When I excluded the lowest velocity from the calculations (788ft/sec) It reduced the ES to 23 ft/sec and the SD to 6 ft/sec These were fired out of my S&W 929.

zzt Posted February 12, 2020 Share Posted February 12, 2020 FWIW, I've found that 1000 fps is the best for knocking down uncalibrated steel. I prefer 147gr factory for that. For calibrated steel, I shoot the normal 132PF reloads. Link to comment Share on other sites More sharing options...
cecil Posted February 12, 2020 Share Posted February 12, 2020 I have no problem knocking down falling steel with my 9mm 124gr plated bullets with a 130 PF …. Link to comment Share on other sites More sharing options...
Joedirt199 Posted February 13, 2020 Author Share Posted February 13, 2020 (edited) Supposedly these will be calibrated for 9mm so we will see. Watched a fee videos of previous matches and they used alot of smaller plates. Just wanting to make sure a bad shot on the larger rifle plate style doesn't slow me down too much. May bump the PF up to 135 and leave the sizing at .357 in hopes of better groups. My p09 with 124/125 range is a 1" grouper at 20 yards. May stick with what works.

9x45 Posted February 16, 2020 Share Posted February 16, 2020 Plates are not calibrated for USPSA, only poppers, at 115 PF. Link to comment Share on other sites More sharing options...

That says a lot of good things about your matches, well designed and maintained steel, well calibrated at the start, calibration well maintained throughout the match.

GMP Posted February 19, 2020 Share Posted February 19, 2020 I've done a lot of knockdown matches this past year with basic 124g minor loads. Only had one issue with a large "tombstone" plate that was later found to have a broken weld on the stop bracket and canted way to far forward. All else no problem. Shoot what works for you otherwise. Link to comment Share on other sites More sharing options...
Joedirt199 Posted February 20, 2020 Author Share Posted February 20, 2020 Yeah I ran some of the more promising loads at .357 diameter and just was not liking the recoil impulse of the heavy stuff. Going back to my tried and true 120-124 lead coated flat point at about 1050 fps. Shoots great groups and recoils nicely. Looks like an order for 3000 Acmes is needed.

Joedirt199 Posted February 24, 2020 Author Share Posted February 24, 2020 Impressed with ACME bullets. Just got my 3000 122 gr flat points. Comes in a nice little wooden box and packaged pretty well. Also came with a package of paper targets. Hopefully they shoot just as well as my penn bullets. Link to comment Share on other sites More sharing options...
