My new Takedown CVA 45-70 likes heavy cast slugs, the 540 RN grain plain base bullets shot just under 1400 fps over the chrony today, the gc 440 grainers shot 1627 fps.
The first shot with the 540's on a target at 75 yds was a bullseye, it was not a long distance shot but I was not expecting a bullseye first shot.
I have 300 more of these beer keg size bullets on order.
Our hunting season is over here, I am already planning for the spring bear season.
