I can pick up a non fluted Rem Varmint contour barrel right now that will finish at 29". I am really looking for a 25-26" barrel, how big of a difference will this make? I am assuming you can cut it off anywhere, it will just have a little bigger than a .830 muzzle diameter.

Re: Barrel Question
How big a difference in what??? Weight? Handling? Velocity? Muzzle dia.? Harmonics? Yes all of those will change with barrel length. You can cut the barrel however long you would like.

Re: Barrel Question
it's possible that if you cut the barrel you'll see a change in accuracy, if the same ammunition is used as was in the prior barrel length...so you simply load for that barrel.
I wouldn't worry about it...if you want a shorter barrel, cut it, so long as the barrel is properly price to warrant the modification.
Go do some research on barrel diameter vs node or barrel frequency.
a link on some interesting info...don't recall if barrel length vs diameter is covered

Re: Barrel Question
I'm looking for a Rem Varmint barrel to finish at 25" for a 300 WM project. I can only find a Rem Varmint that finishes at 29" right now, just wondering what the difference would be if I get the finished 29" barrel and have it cut back to 25 or 26.

Re: Barrel Question
Do it. If you cut it on the muzzle end it will be slightly larger, so you get better harmonics. A good thing. It may add .05 oz's to your build over a slightly smaller muzzle diameter. Depending on the profile you could cut it from the breach end as well. Let your smith help you with those decisions. You could also consider going with a remage barrel. One with a barrel nut like a savage. It is much cheaper and is the design that remington is going to with their newest rifle. A big savings in the cost of smith labor even if the smith does the install. Call Jim @ northland shooters supply to get all the low down on the issue.

Re: Barrel Question
Or, you could push a tight lead slug down the (oiled) barrel, and cut it at the tightest spot you can feel before the muzzle, and guarantee better accuracy.

Re: Barrel Question
The 29" finish length is the max, cut it down from there to whatever you want. Just won't get a 30" out of it.

Re: Barrel Question
The only risk to buying a longer barrel and cutting it back is that the ID of the bore may not be centered relative to the OD of the profile at the point where the barrel is cut. I haven't found this to be an issue with a high-quality aftermarket barrel, but some lower-end replacement barrels and factory barrels can have a significant amount of bore offset at various points along their length.
