Quarter Round.. I don't have one anymore. I've sold it to a friend in Poway, CA. Never shot anything but paper with it, but it performed on paper quite well. The cases showed a marked preference for H335. The guy in San Diego who does this conversion has more info..
I have the Rem 592 and have made several false starts at converting it to the 5 mm Craig, but keep backing off from it. I really liked the rifle as a rimfire and it was great for groundhog, crow, etc. in the small farm and wood lots. I don't think it would be reliable on coyotes with the exception of close range and precision shots.
I'll post on some of the other forums and possibly get more information. Hate to spend $200 plus for the set up and not have a shooter.
quarter round, i had one of those and got rid of it because i couldnt afford the ammo. i have kicked myself ever since and now i know a place with a ton of ammo. they are still proud of it but at least i know where it is. dont re do it. SELL IT TO ME. if you ever decide please give me first option.
The factory rim fire ammo is way overpriced and in ever decreasing supply. The conversion can be done by replacing the bolt head face to a center fire and maintaining the ability to convert it back or machining which cannot be undone. The initial outlay for the starter package is a little more than the price of 4 boxes of the factory ammo.
tnctcb> I don't plan on parting with the rifle.
