For all my life, rifle bullet diameter have been dictated by ammo and arms makers. I never questioned it.
Recently read an article on PO Ackley in 1985 Gun Digest.
Of Ackley's stuff, I have seen some great concepts (improved cartridge design) and at times, some borderline obscene overloads (Maybe powder was a LOT slower back in his prime?)
In it, the author states (Author was student of Ackley at Trinidad CO in 1950) that Ackley took a 6.5 barrel, and cut the chamber to accept 7mm bullets. Ackley concluded that the increase in bullet diameter made no difference in pressure.......
Now, in revolvers, it is not at all uncommon to play a few thousandths of diameter. I always figured that was lead, and it was a different material, and a revolver was a different machine. Just size bullets .001-.003" bigger than indstry spec calls for. No worries
Now, I am not suggesting shooting 284 slugs in a 6.5. But it made me wonder how much of a spike would happen if one used a 7mm slug in a 270? Or a 311 in a 30-06?
I want to state again, I am not suggesting that anyone act on anything here. Just asking for opinions.
