I loaded 25 each of 2.8 BE and 3.2 BE and went to the range today. Both shot well enough and I saw little difference in recoil. But the two revolvers I tested showed definite preferences. All shooting was done standing with 2-hand, modified Weaver stance.

The M15 slightly preferred the 2.8 BE load at 75 ft. slow fire. Both loads shot to about same POI but 2.8 shot a little tighter.

My M10 standard barrel which was tuned at Sand Burr Gun Ranch (action job & hammer bobbed for DAO/carry) shot the 2.8 BE low and left almost off paper at 75 ft. while it put the 3.2 BE centered low in the bullseye. Groups were tight for both loads but POI was much different. In timed fire at 20 and 30 ft. the M10 with 3.2 BE really packed them in center of the bullseye.

I think either load can serve well in the M15 (adjustable sights) but the M10 shooting DA shoots the 3.2 BE much better.

Thanks for all the comments earlier. They really helped.

I will give TiteGroup a try in the near future.
