I swapped everything i could, and confirmed its the barrel, on the other hand i found something that shoots better out of it so thats good.
I confirmed the barrel wasnt moving (though these pencil barrels are crazy flexible). Put a different barrel nut on with no handguard, bolt and higher magnification scope out of a known good rifle, shot 5 different bullets out of it 2 with different powders, and some of the same batch as last time. Same results, everything save 1 was 3moa or worse. The 2.5" group i shot last time shot a 3.5" this time. However it shot a 1.8" 6 shot group of 73 gn eldm over staball match. So i feel like that could be worth repeating with a bigger sample size and seeing if it holds there. Still i will probably buy a new barrel. I dont like being confined to 1 bullet and powder. And really thats already at the limit of what i want from my hunting guns. Maybe ill save the barrel for a ultralight 3 gun setup or something.
Ill say the same as the salesman hah! Its my first can, im the first of people i know, so i have nothing to compare it to. But I have zero complaints. It makes me want one for each rifle. The weight of the can is 8 oz and the direct thread mount is 1.6 oz. The extra 1.6 oz they dont advertise makes it more in line with what other manufacturers offer, but its still at a way lower price. Sound wise on my 6.5 creed I can shoot it without ear pro and my ears feel better than using power tools without ear pro. But i still use ear pro when practicing. The blast/ recoil reduction is significant to me. The poi shift is repeatable, i swap it around between 3 rifles at the moment. The low temperature rating had me scared but i can crank off 15 shots as fast as i can make good shots in my 6.5 and it got to 320* F according to a very accurate temp gun. So still 100 under their max temp rating. This convinced me i could forget about that for my hunting practice. I wouldnt take it to a prs match and defintely not a 3 gun / tactical match, but ive put 500 rounds through it now shooting 10 shot strings one after another in 90* temps this summer and theres no visible damage to the blast baffles. I like it so much I would like to buy a second of these to dedicate one to my main gun, but will first likely buy a larger / heavier / quieter range specific can that can take the heat of competition. I think it fits perfectly into what this thread is all about and would rock on the 6x45. Its a great can for hunting. Light, functional, and not expensive. When theyre on sale i couldve bought 2 for the price of a high dollar can with the same functionality.
