Factory 350 Legend ammo is .355" in diameter.
Hmmm. I looked up SAAMI spec before posting and it stated 0357. Re reading the tolerance is actually 0354min 0.357max. I know I could never be wrong, I check a couple vendors websites and Hornady does publish the bullet diameter at 0.355. What the heck!
Damn, I hate being wrong! Well, at least I could enjoy Pappy's avatar.
And the heck with the 350 Legend. A legend in Winchesters mind.
