Tuner?

I’m intrigued, but not 100% convinced yet? Will move until groups open up and see if I can duplicate those results. If I can, then there is hope for non competitive batches? But am very excited to use a much more precise Tuner.

I didn’t fully explain but the last 3 groups were after fine tuning! If that’s what you call it…

Ya, Mike I’m skeptical to say the least, but it’s been a very cold and snowy winter here in Mi. So I’m playing! 
More than likely it’s a combination of cylinder pressure, and barrel condition, this gun has exhibited a pressure range that it seems to like, 150bar to 100bar will try to duplicate next Wk.

Mike, I got to thinking about your comment about tuners mounted behind the muzzle, with the RAW there is actually more than a inch of sleeve extension past the muzzle. Maybe this plays into the effect a tuner has on these guns? 

JimNM, they were very course adjustments because my homemade tuner uses a set screw not a threaded style infinite adjustment. But that’s ok because it’s very time consuming as is! Let alone a threaded style tuner.

I do have this style to test and will tackle that next.

I will also add, look at how many groups I shot just to find a sweet spot. Do this every time you change a batch of pellets! That’s why I raise an eyebrow every time I see a YouTube video… Three groups outside in various conditions (While tuning) and it’s tuned?

Round two, NT= no tuner, T=tuner, *= adj. in tuner, GB= Gene Beggs tuner no adj. 11th group I cleaned barrel and no fouler’s.q

I’m doing well, I have shot literally 100+ groups with this rifle with different lots of pellets trying to establish competition worthy lots of pellets. I do have a baseline for the particular batch of pellets in this series of testing and decided these didn’t meet my standards for competition?

I was and am hoping the tuners will allow me to take advantage of these lots that didn’t meet my original expectations.

If you study my groups you will notice the 1,3 and 6 groups without the tuner actually looked the best! With homemade tuner groups 4 and 5 also Very concentric and predictable. so this kinda blew my theory of a non competition level batch!? I would love to shoot those in competition! I think when this lot was tested originally it was mid-summer With what I thought were favorable conditions? But got lots of vertical so threw them in the discard side of the drawer.

This is why I like to test pellets in my controlled environment, even if it is only 17yds this gives me a better idea how these pellets will perform at 25m for next season. If I can be confident in my pellets then I know it’s me when I have a bad card.

The rest of this winter I have lots of discard drawer pellets to test with and without the tuners. In all honesty I will probably get confused and burned out! But I am very intrigued by this tuner phenomenon!

This is what the gun is capable of! This target was shot after initial testing.Ok, back at it with the TM-1000, 1,2,3 with tuner at three different length settings.

A,B,C with no tuner at all. #4 was a control group with tuner at best setting. 

All tests with 10 shots per group.

Many other groups shot on separate target but results were consistent with pics I posted.

I agree, kinda makes ya scratch your head a little? Three different tuner’s, two guns, two lots of pellets that I wouldn’t shoot this last season. Pretty much the same results with any combination I’ve tried so far? A lot of time a lot of pellets! I hope shooters using tuner’s really objectively look at their results.

I will still experiment with them, just not once shooting season resumes.

Yes, I will go to 25m but need a baseline and records to go back to when I move outside and condition’s start influencing results. The only way to be truly objective is to try and eliminate as many variables as I can.

I have approximately 17yds from muzzle to target in my basement with no outside conditions to skew results. I feel this is sufficient distance test these tuner/pellet combinations. As you can tell by my targets there is definite distinction of accuracy between groups. (I’ve shot many more groups than pictured)

Just so I’m clear I’ve shot literally 100’s of pellets trying to prove to myself the tuners work? And I’ve made two myself and bought one. Each with different style adjustments and quality’s.

I can almost bet no one up to this point has tested tuners in this fashion, Mike Niksch is one that has and I would trust to give honest results. Manufacturers such as FX that produce them to sell for “their” products doesn’t interest me!
