Hey everyone, A few questions about my model 700. Had it rebarreled by Hart barrels,did a good job with the barrel and bedding it. The caliber is .257 weatherby it has a 26" stainless sporter barrel. Getting a 1.88" group at 350 yards. Is this considered a good group or should I keep tweaking on it? The powder is 73 grains of reloder 25 with a SMK 100 grain bullet CCI LM primer set at 3.250 COAL. Also should i try a different powder that is not so temp sensitive? Muzzle velocity is 3605. Just wondering before I waste my time.
