Krag Accuracy

I shot my project Krag for the first time today using a sling.  She does not like a tight sling.  It appears to be very sensitive to pressure on the foregrip.  Next trip, I'll start loosening barrel bands, etc. and see if that impacts accuracy.  With all that barrel out there a lot of weird things can happen.  Are there any "standard" things that improve Krag accuracy (pressure on the barrel, etc.)?

Didn't you post a super group not long ago?  My best grouping rifle has been worked on extensively.  The rear barrel band has been fitted tight to the wood, so there's no tipping of the band from the pull of the sling. This necessitated a slight thinning of the swivel tab.  The band has been filed inside so that it just touches the barrel keeping it against the wood that hasn't been removed below it.  The barrel has been free floated, including the front of the receiver ring, except where the bands are, to about 1/2" behind the upper band.  The upper band has been worked on inside so that the two bands that wrap over the barrel touch on different sides, but otherwise one can see light under them.  Not wanting to see someone mess up a good thing, and since you said sling tension seems to be cause, I'd start at the lower band, getting it tight to the wood, without being overly tight to the barrel.  Then check it out again before proceeding with other modifications.

It shoots great from a sandbag but the grouping was not so good shooting prone with a sling.  Thanks for the info, that's what I'm looking for.  I have a gunsmith who builds match M1s and 1903s that are legal for different matches but nothing for the Krag.  I'm not going to get too crazy with this one but it really bugs me that the sporter with the original barrel groups so much tighter than the rifle with a new Criterion barrel.

You may need to adjust your loads, try different bullets, or as Madsenshooter said... do some work on fit.  You really shouldn't have a problem using the sling as it provides you a stable third point of support when shooting prone.  Bear in mind - if you intend on using the Krag for CMP match shooting, especially at Camp Perry, you can NOT glass bed the stock in any way!  At the Roosevelt Match last year, they were checking trigger pull and spot-checking some rifles for bedding and other modifications.  If you medal, they will absolutely check!

Mine do a lot better off the bench too.  I was getting groups a bit larger than yours off the bench, but at Camp Perry was hitting 8s and 9s.  But that was another 92/96 that hasn't had much done to it.  I did get the lower band of it tight to the wood so that it doesn't tilt when pressure is put on the sling.  With the upper band, I've found there is both too tight, and too loose, and that pressure is going to change as the barrel warms.  If you pull on the forearm, behind the band, and feel a little movement, or hear a click as you alternately pull and push, it's too loose.  Since you have 5 sighters, start your groups after warming the barrel with 5 rounds, see how that works for you.  I'd certainly not mess with the receiver ring inletting as has been done to my other one.  I found out that if you overtighten the front guard screw when that's been done, you get cracks at the rear of the magazine inletting as that round receiver is pulled down into the inletting.  I have those cracks stabilized with injected epoxy now and the front screw is just snug.  Perhaps this year it will get to take the trip to Perry with some .310" diameter bullets to match it's .310" groove diameter.

Had the Krag out a couple of times last weekend and it shot really well.  I tried loosening the front barrel band and maybe that helped.  Or it possibly could have been that I had bright sunshine and was just seeing the sights better.  The day I first used the sling was dark and overcast.  Any, it did great on everything except offhand.  She is a sweet rifle but that long barrel takes a little getting used to.  I practiced loading and rapidfire with my sexy speedloaders.  Took my new Eddystone 1917 out for the first time but I'm afraid she has a headspace issue. Looks like about 20 thou short which would be about right if the barrel was installed without being reamed.  My buddys going to loan me his pull through reamer.

I had to do some stock swapping, have to sell off one of 92/96s.  I took the one with the best barrel and put it in the worked over stock I mentioned above.  When it's all solidly in there, and with the striker cocked, thumping it on top of the butt makes it vibrate like a guitar string!   When I put the action from that rifle in the stock that hasn't been worked on, when thumped, it's just a solid thump with no "after the hit" vibes, whereas the worked on rifle vibrates a second or so.  My Garand and K31 are tuned like that too.  From the operator position, the Garand goes boink, when you shoot it.  Some of the other guys on the line noticed it too, said it's noisy.  I'd have listed the 92/96 here, but I need the money quick, and it's no collector's piece.  It does however have the only outtie cartouche I've ever seen!
