I would like to try the Barnes XPB 200 grain or 225 grain in my .44 magnum but I don't know if my twist rate is fast enough. I have a S&W 629-6 and I am told it has a twist rate of 1 in 18&3/4".

The Barnes website has twist rate info on other bullets but I didn't find any on these bullets.

Anyone know if this revolver would be likely to stabilize these bullets?

Non issue as far as I am concerned. In my humble opinion there is too much concern in Internet land about revolver twist rates. A 200 grain XPB isn't too long to stabilize for a standard twist rate S&W (I think it is a 1:20) and I cannot imagine the 225 would be either.

Yes they do shoot good out of that smith. I have one and it shoots them great. I agree with the above statement and there have been some on some forums that have done the topic a real disservice. Two things happen imho. 1) alot that talk about twist rate not stabilizing heavy bullets quite frankly cant handle the recoil of the heavier loads and 2) couldnt shoot accurately enough to tell how accurate anything truly is off the bench anyway. I know of about 3 or 4 shooters that can. To give you a good example of this is the bfr and freedom arms 454's. Both guns will shoot good loads of bullets from 240 to 360 grains into groups less than 2" at 100 if you do your part. One gun has a 1/24" twist and the other has a 1/16" twist. Another factor in this is those that say heavy bullets in the 45 colt wont track straight due to the twist and weight of the bullet i.e the 400 gr cast but a 45-70 will stabilize it at the same velocity will stabilize it with a slower twist rate. Then, almost without fail the bullet that it wouldnt stabilize has a deformed nose. I remember an old article about buff hunting with a 45 colt showing a hardcast with a deformed nose that couldnt have possibly tracked straight. However, the poster above has an article in print where that bullet tracked well and penetrated well and very straight, but the noses were largely intact. In a word, if your gun wont shoot it well its either the gun just doesnt like it and it doesnt have anything to do with twist rate or the shooter just cant shoot but the twist rate is irrelevant. Exceptions do exist like the marlin 44 mags with that microgroove rifling and an absurdly slow rifling. Most all production big bore revolvers are not one of those exceptions

Hey Spinsail, while I agree to a large extent with the views above, an easy thing would be for you to send an email to the techs at Barnes. I've always had good responses from them and there's nothing like getting the info direct from the horse's mouth.

I'm with you, Max. I've shot massive amounts of animals over the years with revolvers and have tested most bullets I can get my hands on. Never used Xs in my 44s or .454s, but have lots of them in .475 and .500 S&W.
I've never had accuracy issues of any major source in any revolver with any bullet. Sure, a few guns will shoot a few bullets a little better in some revolvers, but never have I had any glaring problems with accuracy in the short barrels.
It's a whole other story in single shots.

Thank you very much guys. Think I'll order both weights. It really is unusual how quickly you can get expert advice here, and it is appreciated.
