I built up a 308 rifle as a hobby because my savage hunting rifle wasn't very fun at the range (not terribly accurate after multiple shots, too light to manage recoil for longer periods, etc.). After re-barreling and a stock swap, I took it to the local range out to 300yds with some federal gold medal match 168gr and what a difference! I am now interested in going as far out as I can. I also had some 168gr Hornady match that did not group as well (~2 moa in comparison to the ~1moa of the federal). So much started to sink in after seeing the difference between loads and how much variation can come from one to another. A little about the rifle:
- 308win savage SA
- 22" Barrel
- 1:10
- Is there a weight bullet I should avoid buying into because of the twist of my barrel? I don't want to spend/waste the money on any 155gr loads for example if it's a bad idea from the jump or would it depend more on the muzzle velocity of the load?
- I noticed the 168gr hornady match I shot was coming out ~150fps faster than the 168gr federal; does that extra velocity explain the poorer performance out of my setup with a tighter twist barrel? Should I try to find slower loads for the same weight bullet?
- If I want to shoot a few different loads for a few different purposes (i.e., a cheap paper puncher, a match load, a deer load, an elk load, etc.) what range would be best to zero and then use cards/program to make adjustments for the unique load? I'm thinking 200yd zero is too far because lighter or heavier bullets are already moving up/down as are faster or slower loads. Is this why 100yd zero is so common?
- What are some good combinations of a factory match load and a factory hunting load with similar enough ballistics they can use nearly the same zero and range cards?
