Have your tried it without the tuner?
How long is the 100gn bullet?
It might be just too long to consistently stabilise.

I dont have a tuner on it so cant help with that but if you are doing any testing then you should not clean while the test is underway. It would invalidate any results. You may have more going on than just the tuner if the POI and group does not go back to where it was when you reset the tuner. I would take it off until you have more experience with the rifle.

Will try with out the tuner .
I have just loaded some 90 gr speer sp flat base , see how they go .

I also don't allow the barrel to get hot during ladder tests...I feel that keeping it cool is more important than the clean or no clean issue during testing.
It's one of those can of worms topic's, some will say treat your rifle like you would normally, which for some hunters that could mean that the only shot that matters is that single shot through a cold clean barrel.
For others it could be the exact opposite if their shooting lots of rounds for a competition

Kept tuner on and worked a treat , After 12 rounds in 4 different setting got 2 holes nearly touching at 50 m.
Then went back to 100 m and got 2 rounds touch , must have been a fluke .
Looks like ill be sticking with the 90's for now.
Its a bit of a shame coz i have about 1000 proj of 100 sp.
Oh well it will be good when i rebarrel to 6br or dasher in 1/8 twist .
Smiling again

Hi on one wheel
Yes I do let barrel between shots , not till cold but only slightly warm .
I do agree that final shot should be off a cold barrel, if your a hunter .
Benchrest could be different but iv'e never done that .
Cheers

As I said, file the tips off to shorten some 100gn bullets and see if they work, it won't affect their performance.

That's the go.
When I'm out to unleash 50 rounds or more on targets I have found that 90 seconds between shots is enough to keep the heat under control, after my shot I eject the brass and keep the bolt open for the best part of that 90 seconds.
It doesn't seem like long to wait especially if I'm resetting the stopwatch, watching the chronograph, and inspecting brass between shots.
