Barrel twist question
My 22-250 has a 1/14" twist barrel. What size bullets would best suit this barrel, 50 gr. 55 gr.?

According to that link with a 1:14 twist you want 50-52grs. |
RE: Barrel twist question
45-62 gr bullets should shoot reasonably well out of your gun. 1-14" is pretty much what you'll get from most factory rifles, the standard is pretty much the 55 gr.

ORIGINAL: bigdawgwill44 My 22-250 has a 1/14" twist barrel. What size bullets would best suit this barrel, 50 gr. 55 gr.? Greenhill formula: 180/length of bullet (in calibers) = required twist (in calibers)..... So if the bullet is 4 calibers (4X.224") long, the twist must be around 1 turn in 10". How many calibers long are your two different bullets? |

How many calibers long are your two different bullets? However, the base plays more of an obstickle than realized in some cases! And in my opinion it has to do with blow by(or seal), from the case? Spitzer bullets seem to have a disadvantage as far as speed and accuracy because of inconsistancy of seating the bullet when fired? Again this is my 2 cents? But I have found that Spitzer type bullets seem to diffeaint for accurracy when pushed to the limit of speed on fast burning powder rates? |
