Never had much success with RL except in one of my brownings. 85 gr TSX 37.0 gr IMR 4350, my 8 yr. old grandson shot a nice 8 pt running down hill (120 yds. range finder) with this load. Entered rear qtr and lodged just inside the heart. That's penetration from a 243 !!! Wouldn't shoot a 243 unless it was loaded with a Barnes!!
