Re: 30-06 with 208 AMAX effects on game at distance REal world field data is where the truth will lie, and this will be put to the test in about 3 months. While I know this is not exact science it does provide data for a starting point. Just wanted to share as I found this information interesting and useful for my application. This could be interesting for 308 as well shooting this bullet. By using your ballistic program, you have to calculate the downrange velocity to calculate the max game weight that the projectile is capable of lethally taking effectively. The formula calculates for energy at the muzzle. The OGW formula is as follows as according to Bryan's Second Edition book: V³W² × 1.5 × 10¯¹² So considering that max shot would be 800 yards, this load is capable of taking game up to 343# at 800 yards. ![]() So now armed with real world load data and accuracy capability it looks as if this load will be sufficient to take 180# game at a distance of 1125 yards. The nodes were easily apparent so we chose 55.5grains which yielded 2710fps average over my M2 Chrono with IR screens. One load with CCI 200 primers and the other with Federal 210M's.īoth shot well. I loaded up two ladders starting from 52-56.5 grains. The Sig rifle has a hammer forged, 4 groove, 1/10 twist 22" barrel so we were good to go there. So it was off to the range to develop a load using the 208 AMAX. Low and behold that could make for a lethal combination on game out to 1050 yards on 180# game animals. So I start running numbers for the 30-06 tossing the 208 AMAX downrange at 2600fps. He had already decided he was going to roll with is 30-06 as the best choice for effectively taking game out to its max range.Ī few days go by and I am consulting my bed side bible, Applied Ballistics for Long Range Shooting and come across the Matunas' Optimal Game Weight formula. I was of the belief that the 6.5 Creedmoor probably only had a max effective range of 400 yards and the 30-06 out to 600. The only rifles he has available to him are a 6.5 Creedmoor custom rifle, a 6.5 Grendel AR, a couple of AR15's and a Sig SHR970 in 30-06. He has the opportunity to hunt in a great location this year with the possibility to take game out to 800 yards(he is a capable shooter to 1200 yards, before the ethics card gets thrown). A friend and I were recently discussing the lethality effects of bullets on game at distance. ![]()
