I've never seen a RR hole in a precarve that wasn't too tight. Why they drill a 3/8" dia. hole for a 3/8" dia ramrod has never made sense to me. It is ridiculous.....
I drilled out every single precarve stock I have bought, right off the bat. I despise tapered RR's. It is hard enough on your hand loading a tight combo, let alone using a smaller rod.
Besides the fact they intended to keep the rifle slim as they could, I also think the reason they tapered them long ago is because they didn't load tight loads, they loaded what they could Easily load. but that is just my opinion.... :idunno:
