GM Barrel owners please respond

>>How much did the Green Mountain Barrel improve your accuracy (I am looking for 25 and 50 yd group sizes)?<<

Mine shoots uner 1/2" @ 25yards easily with Fed Bulk pack, and these are notorious for lack of accuracy and flyers. Average would be around .360-.400. Never better then .300, and never more then .500. Others I am sure have results with just about any ammo you can buy. I just bought 4 different brands/types to test this week...

>>Do Green Mountain barrels have failure to eject issues when new and if so what did you do to fix them?<<

Depending on the shape of the bullet, some will not eject while others will. I guess it all has to do with which ones dig into the rifling more. This is assuming you are talking about unfired rounds. For rounds that are fired, I have not had any not eject. Mine is new.

>>Did you have to modify the barrel in any way to get it to fit in the action? <<

No. No modifications were necessary on mine. Some people I believe, had a hard time getting the barrel to seat and resorted to heating and cooling to get the job done. I've had none of these problems, but I can say that the fit was VERY tight and snug. All I did was clean the hole really well, and worked it in slowly. The last 1/16" before it was seated was a little tougher, but with a little pressure it seated and nothing else was needed.

Ironchef just about covered all your questions well.

Mine will shoot one hole groups with Wolf MT at 25yds and less than .5 at fifty. These are not frivolous claims. Check my scores on the Match forum. I have posted 250s at 25yds and high 230s to low 240s at 50yds.
Of course there are other modifications to the rifle than just the GM barrel, bedding, head spacing and trigger work among other things plays a part in the overall accuracy of a rifle.
The barrel does play an important part and will make a difference in your group sizes with ammo it "likes".

I say go with the GM, you won't be sorry. JL

The target below was a ten shot group at 25 yards with my GM 16" SS Fluted & Remington sub-sonic ammo… fired in about 30 second. I have done better but did not keep the targets.

There is no way to compare it to my factory barrel, it is much more accurate.

This group is representative of what I get out of my 18" SS Fluted GM barrel. Dynapoints and Velocitor at 50yds. I have done better and worse, but that day I had a camera handy. Other mods I did were VQ TG200, Bell and Carlson Anschutz Stock, VQ Extractor, Weaver GS 6-20X40 Scope. Your mileage may vary with your mods.
