I have been messing with various barrel tuners lately bit commercial and home grown on my rimfire and centerfire rifles and came across a youtube of a guy using a shaft collar as a tuner. A quick visit to Amazon and I had a one inch aluminum collar in the mail. I put it on a Savage FTR with an aftermarket Criterion .260 Remington that shoots consistent .5 MOA groups. I was shooting from a Sinclair bipod and a rabbit ear bag on the rear, Sightron 8 -32 scope. Adjustments to the collar were made using a Starrett dial caliper using the depth rod. Two shots were fired on another target to warm the barrel and foul it. I fired 2 rounds at target 1, adjusted the collar to 2.90 using the caliper then fired two more rounds on target 5 then adjusted the collar forward another .010 inch and moved to target 2. When the first two rounds touched I fired another three. I knew that was a good group so on target three I over adjusted my windage and fired the rifle free recoil. I was pretty pleased with that group so decided to call it good since this is just a FTR rifle. Later this week I will take it back out and stretch the yardage out to 850 and see how she shoots at range.
If you want to try out tuners without spending $150 or more, this is a fun way to experiment. I used a hose clamp on a CZ .22 rimfire to get bulk Remington Thunderbolt to shoot .5 inch groups at 50 yards.
