Reloader 15 - Cast Boolits - .303 British

[Canuck44]

Interested in getting some tested loads using Reloader 15 with Cast boolits using 180 gr - 200 gr cast. I have a Longbranch #4 Mke 1 with a very tight barrel. Sizing my boolits to .312.

Take Care

Sorry Canuck 44...I have always had good luck with IMR 4759 in .303 and .30 cals. with 205gr. SP. Gas check in .303 and 1/2" groups with same powder and 185gr. SP GC in my .308, I have experimented with RL-15 as well as Varget, AA2015, Benchmark, etc....but none could equal 4759!! The one powder I would like to test is AA5744 though.
