Re: More on Barrel Tuners

mmm - its interesting because its loooong been stated that ES doesn't matter SR BR. I assume thats why tuners are a mixed bag in SR BR as really they are a mechanism for tuning on the day which can be achieved other ways. Are high and low powder charges the powder method of positive compensation? - ...

Re: Barrel Behaviour Theory

All, I don't have the experience of others on this site in tuning a rifle but I have spent a bit of time digging into the physics to understand what is going on so that I can learn to tune a rifle faster. I welcome all contributions and discussions. Hi Peter - thank you for your work. I wonder - do...

Re: Barrel Behaviour Theory

ok - I miss-understood your post, but thanks for the pic. i was thinking there might be something that showed how wide the tune was or something like that, which could in turn be related back to the theories presented.
Anyways I won't get this off topic.

Re: Barrel Behaviour Theory

It’s funny how you say the last 6” of the muzzle as this is where I’ve shoved the pink cricket handle grip rubber on my bart .284 ( smithed by Fairbarn) . And also where I say secondary orings should be placed . I would love to spill the beans on how to tune the barrel with orings . But again I’m s...

Re: More on Barrel Tuners

Thanks Williada - great posts and you definitely have my brain ticking over (thanks for the time) - always something to ponder. I have been up to my load dev range this morning to re measure :).

Re: More on Barrel Tuners

I thought I would repost Bryans response to positive compensation theory too - it would appear he accepts it. Note that this 'compensating' effect between MV and barrel harmonics is a known and accepted mechanism for groups to have less vertical at long range than their MV variation would suggest. I...

Re: More on Barrel Tuners

Williada - thank you for the response (always great responses :) )- yes have read all of B Litz books and T Boyers - pretty much anything I can get my hands on to be honest. Sometimes the same concept gets described different ways. I have to admit after watching the youtube and reading Bryans book/s...

Re: KEEP ME IN TUNE

I don't have a bore scope so I reason to err on the side of over cleaning just to hopefully be sure stay of staying ahead of the build up. Plus I make damn sure to get somebody with a bore scope to have an occasional look inside just to monitor the cleaning regime I'm using. Without a bore scope I'...

Re: Stock Rigidity

How does the front rest affect vertical? 'Tis all the same or similar dynamics at work i suggest i.e. inconsistent system movement during the bullets barrel time. I can put forward thoughts on FTR front rest dynamics as that's what I'm most familiar with. Now I'm F Open and wish Rod D was at my clu...

Re: More on Barrel Tuners

what is coning and how does it matter? Is it just me or do those groups look like there is virtually no "width" from one setting to another? i.e. how sensitive to any one change (change could be environmental or a component tolerance) is it? How did the rubber hit the road - i.e. what was ...

Re: Stock Rigidity

FWIW, I have seen a foresight Grub Screw on a TR barrel actually punch through the barrel wall after many shots. The barrel obviously flexed around the pressure point created by the grub screw and a small piece fatigued out of the barrel wall. In general, they are bad news. Peter Smith. I'm guessin...

This is what I have been told by Barnard as well.
