....or home on the range this evening.
I shot a few rounds through my old chronograph, after a luckless event with the new chrony, I recalled my old one from way down south and tested it today. All was well.
The new caliber under test was my 376 Steyr based wildcat shooting 300 grain .411 bullets. I also shot a few 220 grain 41 mag revolver bullets and some Beartooth 250 grain LFNGC's. These were great with 44.0 grains of RL-7 giving 2105 fps. This load of course meant to be a "pot load" for gathering supper when afield. It could well be throttled down a bit preferring something in the 1600-1800 fps range.
The 300 grain Hornady bullets went to 2500 ish fps with 65 grains of H4895 and the 220 grain jacketed hit 2800 with 60.0 grains of RL-7.
RL-7 is a bit fast for best results and I plan to try 10X and some older RL-12 I have on hand, the latter more closely matched with the H4895 burn rate. There are many powders that will work fine and as I go up in bullet weight I'll try Varget and Benchmark. This gun will send 350 grains at 2350 fps. A brief test with some 330 Kodiaks exceeded 2400 fps. This puts it in the 375 H&H energy class and achieved with 8 to 10 grains less powder. It is a real bear gun and I hope my 350 A frame bullet will meet expectations for that purpose. About 2250 to 2300 fps would be great, I will expect exit wounds.
