Got to spend a bit of time at the range today. Took my .350 legend AR, my 10 in. MKII, 7.5 in Super Redhawk .44 and 7.5in. Super Redhawk .454 Cassull. Kinda did things backwards and started with the 454, 20 rds of 300 gr. was enough! then the .44 and the AR. Then finally the MKII. I should have started with that as my groups opened up to about 1 in. normally they are 1/4-3/8. but my hand was a bit sore. Good day though!!!
