All,
I will be getting my .308 F/TR barrel back from Eric today. I sent it to him because of the service I received on my Krieger 30BR. The Krieger shot reasonably well, but I was shooting 250-11x and taking 8th place. Most of the rest of the shooters were using a barrel tuner of one type or another. Not sure how I heard of Eric as I think about it. Turn around was fast and the results, IMO, fantastic.
This puts "load" testing in a whole new light. Rather than fiddle with .3 gr increments on powder and trying to correlate chronies with plots, I just used a chrony to achieve a desired MV, then removed the chrony and used Eric's excellent instructions to shoot the tightest group. My ES averages around 10 or less and I was amazed at the spread change as I incremented the tuner. Turns out the original setting was the best and that's pure coincidence because there is no recommended initial setting.
I was a little worried about whether the tuner would hold it's position because it does not have a positive locking device beyond a rubber o-ring for friction. But it didn't move a whit.
I did the tuning with my Magnetospeed V2 attached. If my ammo was not giving me a good ES, I wanted to know it. The first group was good. Subsequent groups were all worse than the initial setting and all worse by about the same amount. Then I went back to the original setting it tightened right back up to equal with the first group.
I was worried that when I removed the Magnetospeed it would throw everything off. Not true. The attached target (5 rounds) was the last target w/o the chrony and at the original setting.
Of course the tuner setting may require adjustment given weather, temperature, different load, bullet, etc. I think as long as I can get to the range the day before a competition I should be golden. In fact, I think I could use a warm-up match to do the tuning on range day.
Getting back to Eric, I suspect he calls every customer and gets to know them. He's honest and makes sure you're provided with all possible instruction and support.
