Would do better with lighter ammo?
Barrel length, rifling twist rate and pattern, and the job you're trying to do should determine the bullet type and weight. Their are more things that go in to play, but more so with rifles. I'm no rocket scientist or mathematician so that's out of think range now, but my dad used shoot competition and snipe in the army and he used to study all that stuff, things like spin drift, air temp, air density, wind speed, bullet trajectory, bullet speed, bullet weight, and elevation. He taught me some stuff, but I didn't take notes and that was 20 years ago. Lot of physics, weather, and skill go in to play also.
Handguns have some of those rules too, but handguns aren't shooting 6' targets at a grand. I shoot all my pistols with fixed sights, I adjust them once for windage and I'll compensate for elevation.
Chad, just stick to the basics for now then get into the specifics. Most people shoot good with 230 gr. ball ammo. Just practice and that should tighten up your group. When I'm in good practice I'll give you golfball groups at 25 yards, but I've been disrespectful to my weapons and not shooting as much as I used to. Many people have given one piece of great advice with your new gun, buy ammo and shoot, when your done with that ammo get some more and shoot some more. Get to know your gun good, especially it being your first.
