Barrel length and powder burning
I was reading a ML forum and it was stated that to adequately burn 100 grains of powder, a 26" barrel was needed. Was wondering, if this was the case, why do they make 22" barreled guns that will shoot 150 gr of powder?
Will a 22" barrel burn more powder if a 350+ grain bullet is used compared to the same barrel and a 240gr bullet?
Will the slower, heavier bullet allow more time for extra powder to be burned up?
How much powder should be the minimum used when dealing with elk size animals?If 90 grains is accurate with a 300 gr. bullet, would this be enough for elk to around 125 yards?
Not sure exactly how to tell what would be enough for an elk and don't want to find out that what Iwas usingwasn't enough the hard way by losing an animal.
Thanks,
