This #2 Remington rolling block started life as a .32 Extra Long (XL) rimfire. The block is now converted to centerfire and I've been enjoying it for a while. Previously I did a lot of shooting with it with my reloadable rimfire cases. But life is easier now.
.32 Ballard XL is the centerfire equivalent. My cases are made from .25-20SS brass trimmed to 1.085" to accommodate the Accurate molds 31-090S heel bullet, tumbled lubed with Alox.
I chrono'd two loads today. One with 7.0gr of 2400, the other with 7.5gr of 2400. Both ignited by CCI SP primers.
The 7.0gr load averaged 1288fps for ten shots. The 7.5gr load averaged 1471.
Both loads were quite accurate at 50 yards with no leading. But the 7.5gr load had a couple pierced primers. This load seems a little hot at 1471 average. So I will not continue this load. As usual with 2400, there is a fair amount of unburnt powder in the bore. I suppose this contributed to the individual shot velocity variation.
I may try RL-7. That works well in my .32-20 #2RRB. What do you think about primers? Should I try small rifle? Thank, I appreciate your thoughts.
