I'm looking to try out Grendel and am trying to figure out what kind of affordable uppers one can find that provides good 'precision'. By affordable, I'll say under 700 bucks for example, maybe a bit more.
I'm considering factors like barrel length and fluted vs non-fluted. Where I know fluted removes metal and reduces stiffness. But what about barrel length for general groups from 100 yards to 500 for example? Have members noticed any difference in barrel length? Does it matter than much or does everyone just go long for velocity?
Basically I'm looking to print small groups and this cartridge looks interesting, especially if a person moves outdoors. As in if I got say 20" nonfluted, would a person expect to shoot say 0.5 MOA or be all over the map where 16" would be superior?
sorry for the newb question, but after googlind and youtubing today. I found the general deal is a heavy short barrel gives you the biggest leeway regarding barrel harmonics, nodes, etc regarding the muzzle oscillation.

Is there a category for gas operated rifles in bench rest competition? If so, you will still lose against things like a 6mm AR but at least you won't be totally humiliated.
Get the best barrel you can buy. Then you won't have to worry about things like short chambers, harmonics, etc. And you can bet that the barrel will be good. Go cheap and you are rolling the dice.
I offer this advice because knowing you have a top end barrel means you can look elsewhere when you find out that holding under a minute of angle for five shot groups, time after time, day after day, is pretty challenging. And that five shot groups under 1/2 minute are very, very, rare. My bet is that under very good conditions, a guy will hold 3/4 to one minute for consecutive groups fired on different days but using the same range, rest, ammo. This is still pretty good and indicates a good shooter, rifle, sighting system, and ammunition.
