[QUOTE="nralifer, post: 2963142, member: 94556"] Assuming a muzzle velocity of 3150 fps the stability factor was around 1.33 which is marginal. I would try one of two things. One is to take a couple of shots at 200-300 yds to simulate what you might do hunting. The most important shot would be the first. The second thing would be to do a jump ladder with the powder charge you have at 0.010” increments to see what overall length gives you the best 2 shot group and use that jump. Keep your shot at a Deer within 300 yds. Antelope hunting generally is done at a higher altitude so if you hunt these at 3000 ft or higher you should be OK. The warmer the day the better as the air is not as dense. The reason I emphasize 2 shot groups is the barrel will not heat up much between shots and it more closely resembles what you will do in the field. Remember all first shot kills are a cold bore shot and hunting weight barrels are generally thinner, which have less heat capacity than thicker competition barrels. They will heat up faster and could change shape when they get hot. [/QUOTE]
