Tested the new NSA 12.5 gr and the older NSA 15.5 gr slugs at High power today. All targets at 30 yards. Will test at Med power later this week. I seemed to have to have a firmer shoulder fit for the slugs today.
Targets 1-10 are the NSA 15.5 gr. Targets 16-25 are the NSA 12.5 gr. 2 high shot on target #1 were scope adjustment shots. Target outliers are my fault, not fliers. All are 5 shot groups.
10 shots per different slug weight over FX chrony. Removed chrony for accuracy testing. NSA 15.5 average 894 fps, high 898 fps, low 891 fps, ES 7 fps and SD 2.3. NSA 12.5 average 972 fps, high 981 fps, low 970 fps, ES 11 fps and SD 3.6.
Overall I am pleased with slug performance at 30 yards. Will test on Med power later this week then step out to 50 yards sometime in the future.
