tdbru,
Will do on sharing how it shoots, once my new glasses arrive and I can get to the range -- I'm using backup pair that's 2 Rxs old right now. I know a limiting factor when I see it -- or don't see it so well, like my reticle currently.
The barrel is 1-9 twist, 6 groove with a standard SAAMI chamber. All the build details are here https://www.65grendel.com/forum/showthre...-5-Grendel.
Despite my choice for fluting to lighten the barrel, the rest of my setup is not designed with weight as a first consideration -- though some parts I chose for other reasons, like the BAD titanium takedown pins, are great light weight options. The scope, battery and sunshade come to about 2 lbs, and the MBA-3 stock is around 1.25 lbs.
I just realized my scales are either precision ones below 2 lbs, or imprecise ones in the hundreds of lbs. range. Any suggestions on a good scale? Digital fish scale appropriate for weighting gun parts? (I could justify buying that to myself without too much in the way of mental gymnastics.)
Also, I noticed that x-caliber doesn't offer 5R on 1-9 or 1-10 twists in 6.5mm/.264" barrels. The idea of radial rifling is one that appealed to me, but not enough to move me off of my desired twist rate. Is radial rifling problematic above certain twist rates at a given diameter? Or is not offering 5R in 1-9 and 1-10 just a matter of the tools they have as a result of market demand?
thanks,
Morv
