I cut down 40 pieces of brass and plan loaded up 325gr flex tips for my 450 Marlin BLR. Using IMR4198.

Wondering if any of you guys have used the flex tips in 450 cal and what was the accuracy. I've heard they work well on game.

I've shot the hornaday factory loads in a Marlin 336 chambe in .35 Remington. 5 shots in one hole.
