Hawk bullets www.hawkbullets.com make some odd caliber/weight bullets. Besides the normal 200,225 and 250gr .358 caliber they make 275gr and 300gr. Also North Fork bullets make a 270grainer. While these are probably not needed in a .356win they are out there. Also Mt Baldy bullets makes a 280gr gas check cast, as well as a 240grainer. I have a BLR in .358win and a Savage 110 in 35 Whelen, oddly enough the Whelen has a 1-14" twist rate while the BLR has a 1-12" rate maybe the lower velocity of the 358win dictates a faster spin with heavier bullets? Love them 35's

As a side note i just bought a 336 in 375win and i cant wait to see what she will do!!!!
