Re: 22/243 rifle:
In answer to the question of loading the 22 Middlested (22/243), are we to assume that everyone is shooting a fast twist rifle? In the event someone may be interested, I will add that I've a 14 twist 27 inch Lilja barrel and am shooting the 50 and 52 grain bullets between 4200 and 4225'/sec. A great powder for this is Reloder 15, but I'm interested in shooting this outfit during varying fall and winter tempeatures of 40 to -10 degrees. Regardless of what Alliant indicates, this powder IS affected by temperature swings. Therefore H4350 is gettin' 'er done for me.
