VQ Range Report
I took the new Volquartsen (VQ) barrel and the rest of my 10/22 TD gear to elimsprint's backyard range today for some in-depth testing and tuning today.
Have I mentioned what a great thing it is to have a friend who has his own range, is a talented amateur gunsmith, is very experienced with 10/22s and has his own machine shop? Last visit he gave me an aluminum muzzle brake that he built, to replace the brake on the AT barrel. The one that comes with the AT barrel has holes all around and blasts your hand with gas and powder debris. The new custom brake only has holes in the top and is much more comfortable to shoot. Today he adjusted the indexing of the muzzle brake and chamfered the ends of my delrin buffer (it is soooo much easier to install now!). I know I could have chamfered the buffer with a file, but it is so much nicer when done on a lathe
VQ barrel accuracy:
Initial testing with Federal AE at 25 yards was pretty disappointing, but switching to better quality ammo (SK Rifle Match) resulted in a huge improvement:
Sticking with the SK RM at 50 yards resulted in a few very reasonable groups. I am happy with this result, as I think there is potential for even greater accuracy as I continue to experiment:
VQ/AT barrel reliability:
As far as reliability is concerned it was a case of 2 steps forward, one step back today. I was using the VQ and AT barrels, but not the standard Ruger barrel. My friend and I spent several hours tuning spring weights (Kidd 3 spring kit), trying different bolts (Dlask and polished & radiused Ruger), different magazines (new and old), trigger adjustments (the Kidd single stage was acting up), etc. It is proving challenging to find a tune that works for both the 16" VQ barrel and the 9" AT barrel. As my friend pointed out, it may be that there is not a combination for bolt, spring weight, trigger adjustment, etc that will work with both barrels (at least with this ammo). I hope this is not the case, and intend to do a lot more experimenting to find a solution. I did try a few mini-mags with the AT barrel, but did not notice a significant improvement over the Fed AE rounds. More to come...
Bushnell 6-18 x 40 Rimfire Scope, Warne QD rings:
I was
very impressed with this scope, given its extremely low price ($160 +/- after rebate, including tax and shipping). Size/magnification/weight/balance seem just right for the VQ barrel, it is extremely comfortable shooting offhand and works well from a rest. I will need to do more testing to see how well the Warne QD rings work regarding point of impact variation, but they seem like a top quality product.
