I had a nice leisurely walk in the woods Monday afternoon and took along my H&R 223 with some cast squirrel loads. 2 shots, 2 eastern gray squirrels for the pot. 3.5 grains Red Dot, Lee 55 grain flat point cast of range scrap and lubed with liquid alox. Yes, the barrel has been lopped to a barely legal 16.5 inches. Still not much more noise than a 22 lr and a lot of fun! Not chronoed, but they do have a super sonic crack. Dropping the charge to 2.5 grains gets them into subsonic territory. Farthest shot was only 30ish yards, I like them in close! Bullet casting adds so much versatility to a rifle! Non cast shooters are missing out!
