[QUOTE="azsugarbear, post: 831732, member: 4809"] Welcome aboard. I shoot 243 as well and I have been wanting to try some V V 500 series powder with my 105 gr. bullets, but it seems hard to come by these days. As a general rule: given the same caliber, the lighter the bullet, the bigger the powder charge required to reach max pressure/velocity. So take the charge for your 85. gr. bullet and back off about 2.0 grains, then start working up to your max load. Max load for your 80 gr. bullet should be about .5 to 1.0 gr. higher than your 85 gr. bullet. [/QUOTE]
