I have a 629-1 8+ brl that I have owned since 80s .It has been well shot carried in the field and has taken a few deer some hogs ,coyote and numerous other critters .I don't use the heaviest loads as I just don't see the need personaly .Your 629-1 is beuatiful and yes you stole it for 650 that wouldn't touch mine and it is well used and shows it but I love that gun and you will love yours .Mine is so smooth and accurate it is truly a joy to hunt with and it is my comparison gun as far as trigger pull action ect goes.i have run any many rounds thru mine and still do it is just as tight as the day I bought it in like new condition about 1986 .Like I said I don't see the need for those super heavy loads I mean it's a 44 mag and it will take anything on this continent .Anyway I hope you enjoy mgreat score on a great gun.
