I bought the RCBS 35 FN GC mold a while back. I heard It was THE bullet for the 35 Rem. I cast and loaded 20 over IMR 4227 and went to the range. First I shot a few rounds I had loaded with a Hornady 200 jacketed to verify zero. I next put 3 of the cast loads in the tube. They won't chamber in either of my 336's. These are sized at .360 and crimped in the crimp groove.
The Hornady loads have shot well in both guns. The OAL is longer with the Hornady bullets. The RCBS cast load is hitting the lands and not allowing me to fully close the lever. Can you crimp over the front driving band in a lever gun? Seems like you might have problems with bullet set back.
Any advise out there? I'm disappointed to say the least. I had high hopes for this cast bullet in the 336's
