I bought a Marlin 336 .35 Remington a couple of years ago to "match" my Marlin 39A and 39M that are family heirlooms. Iowa has recently allowed the .35 to be used for deer (we were slugs only), so I'm looking for a load. It shot pistol bullets reasonably well, but I finally stumbled upon some Hornady 200 grain round nosed Interlocks and they seem to keyhole. I started using H335 at 38.3 grains. That keyholed badly. I disassembled the rifle and gave it a thorough cleaning. It still keyholed. I the tried IMR 4064 at 38.1 gr and 39.9 grains. I also tried Varget at 36.0 & 38.3. I'm shooting offhand with a sling supported from 45 yards. It is still keyholing pretty dramatically. Any suggestions?
