[QUOTE="Drisnylan, post: 674844, member: 51172"] lightbulbWell, last night I learned why 6.5mm and 7mm bullets are so good, and it has to do with the fact that the first guns made for that caliber had fast twist barrels at around 1:8 to stabilize heavy military bullets (m96 sweed and 7x57's) when spitzer rounds came in the form of the 8mm mauser the bullets for the 6.5 and 7mm needed to be updated, consequently, the fast twist barrels allowed long lower drag bullets to be used to achieve better accuracy. The original 6.5x55 loading from 1894 to the 1940's was a 156gr round nose, when they updated, the twist allowed 140gr spitzers to be used. Bullet makers had to make bullets to accommodate the military 1:8 twist.

I say rifle makers need to get their heads out of their *ss and make guns in the right twist haha AAAND with that said I will be building it in 6.5x55 A left hand boyds featherweight thumb-hole stock is on its way along with a bold trigger and a new action screw set(the current ones are pretty janky).
