In 1960, just before my college graduation, I made the only serious mistake I have made to date in handloading and ended up with 60 grains of IMR 3031 behind a 220 grain cast bullet in my 1917 Enfield .30-'06. I survived it with no permanent injuries but the rifle had developed headspace. Having read a long article in Gun Digest about the .35 Brown Improved Whelen, I sent the rifle off to P.O. Ackley to be rebored to .35 caliber and rechambered to that caliber. Until this year, I had never killed anything with it. Something always seemed to come up in the way. This year, however, I bagged a healthy sized buck and can report that the cartridge killed him dead at about 75 yards. The load was not chronographed, however.
No headspace problems.
