Tuner on 30BR?

[Pete Wass]

I think what I see---

when I test; I do it the same way you have shot this target, is if a barrel shoots well, the cloverleafs can be made round and small and will forgive the one that slips sideways most of the time unless there is a drastic swing in conditions. Even shooting with flags, my test targets look very much like the one you posted.

It also seems that a barrel that will produce repeatable round holes will shoot well all day. I find that the ones that shoot small cloverleafs do not shoot well all day long; out of tune I suppose.

I haven't had a lot of time to tune in the past but now that I don't have to go to work every day I am going to spend a lot more days at the range finding out some of the whys. A problem with shooting the rifles I do is there aren't many of them around where I live so not many folks to exchange info with. ( HBR rifles) We tend to shoot different chamberings form each other. This is one of the problems with "Wildcatting". I guess one should do something simple/smart like just shoot 308's, aye?

If you can't tune the clover leafs out with the tuner, chances are the barrel isn't worth any more of your time. No different than not being able to do it with conventional methods. For the most part, I feel that a properly made tuner gets the vertical out, and gives a bigger tune window...not much more than that. A non-competitive barrel can't be helped by a tuner...it may make a little more predictable, but it won't make it competitive. As for the Temperature/Pressure/Air Density stuff, ask Gene or anyone else if they go straight to the record after making an adjustment to their tuner? Sorry, I don't think anyone will claim to have a system that works 100% of the time and can be linked to some atmospheric condition...

Self admitted spectator here, but shouldn't a tuner only remove the vertical. The clover leafs we all hate require both vertical and horizontal movement. I usually attribute my horizontal to my in-ability to read flags and can usually see it as soon as I pull the trigger and respond with the approperiate duhhhhh...

Horizontal Spread &Tuners

I was at the Tomball Gun Club practicing with Jackie. He was getting a little horizontal in his groups. Jackie adjusted his tuner 1/2 turn out trying to tighten his groups.

It did not help in this particular incident. He came to the conclusion that this Kreiger had given up the ghost and screwed on another barrel to get back on track.


I also thought that tuners targeted verticle only. The next time I have a little horizontal I'm goin to play with my tuner.....


Maybe Jackie will chime in and give us his thoughts on horizontal spread and tuners...

Miss-Conceptions

There is a miss-conception among shooters that just because a Rifle is shooting flat, it will agg. How many times have you seen shooters looking at the wailing wall and comment about a .400 straight accross catepillar and say, "well, at least it's tuned".

The odds are, it's not. If you have a barrel that seems to shoot flat, but gives way too much horizonal for the condition, then you probably have a barrel that is either tired, or not that well tuned.

The senario that Vic is referring to was at Tomball yesterday. I had a barrel on my favorite Sporter that is on the 3d set-back. This barrel has always been a great one. But, I have noticed that it is now VERY sensitive to even the slightest twitches in the condition. You just can't win anything with a barrel like that. Sure, if you hit the condition absolutly perfect, it will shoot small groups. But a barrel has to give you something, certainly more than that!!

I had several spares with me, screwed another barrel on, and my flag reading suddenly improved about 200 percent.

Incidentally, I have my two new 50x March Scopes on my favorite Sporter, and my brand new Sporter based on the Stiiler Diamond Back. Both Rifles are shooting quite well, I plan on making a report to the Forum on these scopes later.........jackie

"2" new Marches? I thought having to pay for just one of the March scopes was enough to give you heart burn.......................Don

My point was that you can tune the rifle with powder charge, seating depth changes, or a tuner...but if the barrel wont shoot round holes, you're wasting your time. Tuners can remove vertical and even "clean up" round, but larger than acceptable holes to make the barrel competitive. But IMO, no form of tuning can help a mediocre barrel.
