I was able to get out and shoot my 32 today. Here are the results:
Marlin 1894 Cowboy
32 H&R Magnum
Leupold 2X7 scope
All loads were shot from the bench, off a rest, using a rear sand bag. I shot at paper targets placed at 100 yards. The temperature was about 80 degrees with almost no wind. All groups were 10 rounds each, fired consecutively, and allowing the barrel to cool completely between groups. Even at 80 degrees, the 32 didnt get all that warm after 10 rounds. The velocity data is for the 10 round average using my chronograph.
I loaded up two bullets and two powder combinations. I used Alliant Blue Dot and Hodgdon Titegroup along with Hornady 85 grain XTP jacketed hollow points and National Bullet Company 95 grain LSWC which were copper coated. Here are the results:
85 grain Hornady XTP/Titegroup
3.0 grains 935 fps 3 ½ group @ 100
3.5 grains 1144 fps 1 7/8 group @ 100
4.0 grains 1313 fps 2 group @ 100
4.0 grains 1325 fps 2 1/8 group @ 100
85 grain Hornady XTP/Blue Dot
6.0 grains 1210 fps 2 7/8 group @ 100
6.0 grains 1225 fps 3 group @ 100
95 grain NBS LSWC/Titegroup
3.0 grains 1149 fps 5 ¾ group @ 100
95 grain NBS LSWC/5.0 Blue Dot
4.5 grains 1050 fps 4 ¾ group @ 100
5.0 grains 1131 fps 5 5/8 group @ 100
I noted that Blue Dot did not burn completely. I had un-burnt powder flakes in the action, on the bench, and in the barrel after shooting. I probably wont use Blue Dot in the future.
The lead bullets gave pretty poor accuracy. Ill have to try other loads to see if I can get them tightened up.
The Hornady XTP jacketed bullets performed very well. Combined with Titegroup powder, they shot well and burned extremely clean. Velocity was high and Im still not at the maximum book load yet. Ill continue testing this combination.
I did also shoot at 25 and 50 yards with the rifle. 25 yard groups with pretty much any load ripped one big hole in the target. 50 yard groups were all an inch or less with many shots touching.
Functionally, the rifle performed perfectly. My only gripes are that the trigger is just horrible and the tube feed loading is a real pain. I shot several stings offhand and loaded the tube to capacity. Holding the rifle, the ammo, and trying to fish the rounds into the gate resulted in me fumbling many rounds to the ground.
I think its a keeper. When I shoot again, Ill post more results.
