It is, but have a smith look it over if in doubt. Go to graybeard outdoors site for specific information on frames and lots more details. You can have it reamed to max by a gunsmith who has the reamer or you can rent them and do it yourself. I had mine done by a local smith. He's done over 50 and I know several people who shoot them. Hand load w 1680 and 180 gr ssp but those bullets are hard to find now. We'll worth it, especially if you hand load, then it's a no brainer. Totally different gun with a lot more range and umph but no extra recoil.
