"John, did you actually shoot out that #1 barrel with cast loads? What caliber? How many rounds?"
========
It depends on your definition of "shot out". It was shot out for the bullet I was using, and all 22 bullets on the market at that time which were all designed for the 14 and 16 inch twists universal at the time for production 22CF, The 22 is not competitive in CBA competition with these bullets with their BC which are lower than whale dung. At least nobody has ever proven otherwise. Ruger claimed a ten inch twist for their 223s in the early 1980s and I designed a round nose bore riding 71 grain bullet that would stabilize in it according to Greenhill. Walt Melander of NEI made the mold and called it 71224 in his catalog.
I used the #1 and the bullet for about ten years and won lots of postal matches and my share of 100 aggregates at a couple of our nationals but it wasn't competitive at 200 yards with me aiming it.
Over the years as the throat eroded I beagled the mold till at the end the bullet nose was over 0.002" lop sided and still shooting very well. But eventually I couldn't get good nose fit with enough of the gas check in the case to hold it..
I regret that I never dug it out of the safe and tried my 80 and 85 grain NOE and Mos bullets. I might have stabilized them although no matter how many times I measured the twist it came out 10.7 inches -- very odd.
As far as working on the trigger, I may give it a try if the cabin fever is bad this year.
