Ammo Question/Tuner Question

[VLNBYR]

This is why rimfire BR is so frustrating. The 388 group in the tuner testing is as good as you will ever get. Then with the tuner set at 388 you shoot 10 shots and there are only two that can be combined into a 2 shot group that is as good as the 5 shot group.

could just be the loose nut behind the trigger too LOL, seriously I found myself bumping the windage adjustment on the rear rest with my chest today, from now on I have to make a conscious effort not to do that as well as concentrating on follow through when squeezing the trigger with my left hand


there is a lot to this game and I know I still have a ton to learn

@gunsandgunsmithing

interesting, next half decent day we get I will do the 5 shot 15 group test



that's exactly what I normally do on my typical score, decent scores, low X counts, plugged 50's




no wind at all today, aluminum bed in the rifle. Action screw torques maybe ?

Maybe on torque but the aluminum block...I'l just say that I've messed with a few and they never shot great. Good but not great. I have seen improvement by dampening them. They are almost always better after good bedding work, too. Most only touch in a couple or maybe three places...Just not ideal.

I can usually pick that up by looking at targets. I don't think this is on you unless there were light conditions you weren't seeing. Flags or not?

since it was a windless overcast day I only had 1 flag out at the 25. Never saw the tail move until the very end which was about when I had finished with the tuner and shot the target. Even then the tails just wiggled a little. As I said earlier the "wallowing" as VLNBYR called it is about the norm for my targets, even in factory class. I have to wonder if it is not something in my setup or technique that is causing the shots to be off just a smidgen when shooting for score that does not show in group shooting

@TRSR8 I just read a few posts from Bill he obviously disagrees with Kolbes theories About positive compensation. Do you agree with Bill Calfee?

#134. You’re dead to me sport.

Oh well you can't win them all.

Mental?

 

[JimSC]

Mental?

yeah my wife is always saying I am a mental case lol.

Possibly, it happens less with a good crosswind than in the calm which makes me think it may be my concentration. I am working on that rereading Lenny Bashams book again. I want to try changing my hold back to a lighthold on the forearm and shooting head down. I may change my bench setup around again also. I have never been overly happy with that mechanical rest and shooting free recoil head up

Only had this rifle a couple of weeks and this is my first year in unlimited, if I fall down a couple of times until I find my sea legs it ain't the end of the world. My wife also says I may not be the smartest man in the world but I am the most persistent and I am not afraid to try new things and change the way I am doing something until I find what works

 

[Doc22]

Smart enough to listen to your wife means plenty smart to me

This is what you can do when you get your rifle right, good ammo, and some good conditions. Outdoors ARA at the Chiefs range Dec.2.

did a test with Lapua CX this afternoon, perfect test weather zero wind. This time I started lower and went up in 2 click increments. Afterwards, I did 10 shots at 378 then 388. A bit too much horizontal at 378. For reference, the circles are 7/16 OD. At 388 I ended up with a CEP of 95% @ .243

Jim, did you use the center of the target as POA? I know 388 looks really good but as you seen anything low and left will not be repeatable. 372 is the only promising setting since it is at least centered and at the horizontal line. you want settings at or above the horizontal plane. anything below will not repeat.

That and a shooter who knows what he is doing. great shooting!

We need to agree not to discuss targets from my first years of competition. They didn't look like those.

yeah I was using the center trying to get that sine wave effect

Put a few clicks in the scope so the poa in'st muddied up.
All barrels will show it, the better shooting barrels its a little harder to see.
Also, if 1 click screws the group up to badly I'd be looking for a happier (broader) window.
As Lee said, you absolutely don't want to be on the bottom of the wave. Those tight groups are apparitions. Been there, done that.

Jim, here is an example of what I look for. you will note a 10-click adjustment spread and the groups look similar but only one is what I am after. as noted, this is a factory barreled and stocked 1413. it will be 5-years since I tuned this rifle, and it remains at 90.

@gunsandgunsmithing Finally got a chance to tune today this is the first revolution 0-24. Sk semi auto at 50 yards. I see groups 7 and 15 as the best. Other than. That I don't know what else I'm supposed to see.
The second picture I went through the whole range 0-500. One full revolution at a time. I think the best range is 375 -425
The last picture is 375 -425
I like 405,420 and 425

 

[PWNolan]

Tough to tune with something like SK Semi-Auto. Unless it's a really good lot# and it doesn't appear to be.

Otherwise I'd be looking hard at 18 & 20
