Re: 6.5 150g SMK

Does anyone know anywhere in Australia that has these available? I'm guessing they will be around $1 a bullet. Has anyone tried ordering sierra bullets from one of the US places directly to try get them cheaper? how much red tape is involved? thanks Look up reloading international, there is a bit o...

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. No worries , time to let the real people hav...

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: Barrel Behaviour Theory

John, there is a nightmare of different vibrations patterns to get your head around as we try to identify their sources, then try to work out how they mesh or interact and a lot of blokes who are specialists in this field know more than me. Yes, seeing some of those changing sections induced from t...

Re: Barrel Behaviour Theory

I found it , I’ll bare all !! This was written a while ago and is not very tech ! But here it is my little thesis on Barrel harmonics. Which way to move the tuner , jumping , jamming , barrel timing and ocw: First up a disclaimer: I have no accolades next to my name ! So take my theories as just tha...

Re: Barrel Behaviour Theory

In your moving graphic Peter you showed the blue line with peaks much higher than the main waves, this is in theory what using a tuner should be aiming to control, reducing the radical peaks, and potentially increasing or decreasing the frequency of the other waves thus reducing and or stabilising ...

Re: More on Barrel Tuners

I’m sorry for leading everyone astray with hard shouldering or free recoil, Alan’s Math says it plain and clear . But my experiences at times says otherwise . Oh my gosh ! This sport is off the chart as far as for thinking stuff over !! All of the newbies I think are about to jump off the end of the...

Re: More on Barrel Tuners

We are getting off topic , but plenty of my own testing during Development squad seemed to susggest keeping the same position especially with the shooters elbow . Even with a mag speed I’ve seen some differences . I’ve heard of larger massed shooters getting another 20 fps out of the same rifles wit...

Re: More on Barrel Tuners

My own experience with muzzle velocity variations reveals just how easily it changes, even with the gun handling. Yep I've found u can get huge velocity changes , whether u free recoil , semi free recoil ( what I do ) or preload ( like I do with my Omark .308)30 fps from my experience. I used to wa...
