Tuner experience

[BartsBullets]

Tim. I've never had to find a correct seating depth and put the tuner on. All I've done is seat the bullet until the marks on the bullets are more square than long and adjust the tuner accordingly. 95% of the time I can find a sweet spot right away and if I can't I usually go up or down on the powder charge instead of the seating depth. The only time I will adjust the seating depth is when it stops shooting and the tuner doesn't seem to be helping, I'll seat it out about 3 thousands because of throat wear and it seems to come right back. Just my 2 cents of what's been working for me.

JIm,

I agree with Tim. I think you are leaving a lot on the table and don't realize it.

Maybe your right Bart but my rifles have been shooting awfully well the last 2 seasons. I'll try it your way next season and see if there is an improvement.

I'll just add my .01cents cause that's about all it's worth
I'm a believer in tuners but again you have to spend the time finding the correct seating depth for each barrel then put on the tuner or you will be in the middle of the pack wondering what those guys at the top are doing

I don't disagree except to say that I prefer to add the device to the barrel before doing the load work up. It just makes sense to me that if you're gonna add several ounces to the muzzle, that that's the way the load should be developed. Just don't touch the tuner until you have that load.

That said, I admit that it does work to do load work with it on or off and the results seem about the same...and that it blows my feeble mind...but it works. It doesn't take much sometimes.

With Winter coming on i am really looking forward to another thread centered around that "Positive Compensation discussion for another time" Talking stock design, barrels, balance ect. ................

You trouble maker!

Your gonna need to use the search function. I think we beat that horse to death.

I searched Positive Compensation and didn't find squat. Not even a beat horse. Am I missing something?

There you go. Its one of those deals that unless you actually get out and do some tuning at 1k you'll never see or understand it. It is real and see it every time I tune. Of course like every thread with any "substance" it goes sideways at some point.

 

[Alex Wheeler]

This winter I dont plan to get into threads about PC. I do want to try and find a way to tune at closer range that will find the center of PC at 1k. I also want to do some shoot through targets with colored bullets. Still a lot I want to learn.

Don't let the naysayers worry you, you are doing good work and I for one appreciate it!

Thanks Alex. I do remember this thread now that I've looked at it. Looks like a cure for insomnia...

My understanding is that a 22LR should use two different tuner settings if you are going to shoot 50 and 100 yards. If this is the case, fore i have not tried it, i don't see why the theory wouldn't apply to centerfire as well. So i will be looking forward to reading quite a bit and learning from you guys that know more about than i..

Man, you just let the cat out of the bag.......

I've been using a tuner (Bryant Precision) shooting F-TR for a long time. Best thing I ever tried.

Are Tuners legal in FTR?

 

[lawrence97]

Are Tuners legal in FTR?

Yes, they are allowed. As long as your system meets the weight requirement you are good to go.

 

[R.Morehouse]

I have done PC at 1k and it works great. But like Alex was just saying......he is looking to try to find out how he may be able to tune at a closer range to get the desired result at 1K. That is one aspect of tweaking the system i was referring to when i mentioned a new thread over the winter. As well as perhaps some of the others mentioned earlier. Up North here there isn't nearly the shooting going on as during the "season" so when there is this extra time and so many extremely active and capable minds here it is always more than a little interesting to see them come together to perhaps improve on our addiction........Just Saying.

I just did some testing to compare 100 yard vs 1000 yard tuner settings. I tuned my rifle at 1000 yards with ladders for powder and seating (pc) and I never shot the rifle at anything other than 1000 yards. I also never changed my original powder charge or seating depth and the rifle now has 450 rds since initial testing. My original charge and seating gave me a 589-23X at a recent 1000yd fclass match during my last outing with tuner on 0 and some high winds.

Another shooter had mixed feelings tuning at distance and his results were not giving him confidence so he fell back into tuning at 100 and ended up pretty darn close to what he came up with during 1000 yard testing for powder charge and his seating depth test at 100 matched his 1000 yd testing.

For the sake of testing, I decided to go out of my way and check my load at 100 yards. This was difficult because I have not shot at 100 in years. The closest has always been 200 yards.
My first 2 rds at 100 we’re sighters (tuner at 0) and then 4 rds thru the same hole. I then moved to a fresh target and did a full tuner test. Tuner at 0 gave me 0 vertical but 3 rounds in a horizontal string. I tested from 0 to 18 hashes on my EC tuner. Setting 10,16 and 18 were the best.

At the end of 100 yard testing I decided to take what I learned back to 1000. At 1000 I tested settings 9,10,11,16,17,18,19, and 20. 11 looked decent, 18 and 19 were good, 20 went out of control. Then I figured I would split hashes and try 18.5 and that’s we’re things tightened significantly. I shot 10 rounds under 5” of vertical.

My conclusion is that a tuner setting at 100 does not entirely translate to being the best setting at 1000. Nor do I think you can set and forget unless you are constantly adjusting your seating depth or powder charge. I’ve also run into situations were the load is tuned so good that playing with the tuner made things worse.
Now, with my busy work schedule I do not have the time that some have to test or tinker with fine tuning weeks or even the day before a match to find that perfect combination of powder and seating depth. I am trying to stick with the charge and seating depth that did good initially and just mess with the tuner when vertical starts to get out of hand. I have attached a 100 yard target to get an idea of what the tuner does at 100. I will also post a pic of the 1000 yard tuner test target this weekend.

 

[savagedasher]

The best target you have is 10 . And I wouldn’t call it a good tune .
Looks like you using numbers and going past a good tune .
I don’t want a half a bullet of vertical at 100 to shoot at 1000 . Larry

@Lawerence97 -did you/will you go back to 100 and see what 18.5 does?

I do not intend to go back to 100. I only did it to compare with my buddy and out of curiosity since I have not shot at 100 in a while. I have 1000 yards available to me at any time as long as other shooters don’t beat me to the range. I mostly shoot at night and at 1000 yards since that is the distance I compete at. I will test my setting at a match in 2 weeks and see how it goes. I rarely have time to tweak so I need to make my limited sessions count which is why I go straight to 1000 yards rather than play at 100 and then verify at 1000 and continue to tweak.

 

[6BRinNZ]

Thanks for the reply. I was curious to see how tight it shot at 100 as it is often said what works best at 100 isn't best at 1000 but rarely is the tune at 1000 taken back to 100 for a comparison.
I know I don't simply because there is no need other than interests sake.
Appreciate your time and effort.

 

[Alex Wheeler]

Your best tune at 100 will be very close to your 1k tune. But that small difference makes a large difference at 1k. There is no "window" at 1k, you have to be right on it to shoot really small. The key for me seems to be figuring out where in your close range window to load for 1k.

Yeah - I'm simply curious to know if the 1k tune makes the 100 yard group smaller.
My practice will get me to a repeatable .4moa vert at 1000 but that would be a country mile from what a 1K br guy would call small.
