My Ruger #1V has a 1:10 twist barrel. My "light" load is an 87 grain Sierra bullet with H4831 powder. My "heavy" load is the Nosler 115 BT (shown in the photo above). Both are scary accurate. I bought the gun thinking it could do double duty for deer and varmints. Too much gun for varmints so I put a fixed 6 power scope on it and use it for deer. The variety you get with a 22 caliber rifle is much greater (and cheaper) for varmints. Plus it gives you the excuse to get another gun.
Gun control is hitting what you aim at..
