Annie 2013, 10.5 lbs, front rest tension and its effects.

[deffie]

Hello everyone,
as you may know Anschutz 2013 action with barrel is quite weighty by itself, i'm on a (stripped down) 1kg wood stock and without barrel tuner; during my last match, after shooting some bad shots and looking for a solution i noticed that playing with front rest tension over the stock would help, this made me to hit the last fifteen 10's. I keeped this lesson for the next target and it did go way better than the first: 246 vs 240. Four points away from the 250 by two honest 9's and one bad 8's still produced by vertical stringing; lately i noticed that this stringing is always higher than the POA and never lower.

I was 7 shots away from the end of the 246 target when i had to get a new box of the same lot of the same ammo, I moved on the dummy targets to see what the new box was going to say, i shoot 3 shots with the same front rest tension i was using before, these 3 shots, in the eight ring, 120° one from each other were making a quite large triangle with the 9, 10 and X rings into it; i changed dummy targed and i lowered front rest tension to zero, this time i've got 3 shots in the same hole, i came back to the real targets and completed them with 7 10's.

I've been to the range yesterday, tried different front/rear rest settings, did a deeper cleaning with a solvent after 2k shots with just plain cotton without solvents, seems that it improved the accuracy but the high 8's still happens and i'm still looking for a solution, tomorrow again to the range and this weekend last match before the semifinals.

Any clue ?

Thank you

Along with front bag tension you also need to have the forend stop properly located so the rifle has enough weight on the rear bag. If your rifle has a forward cg then the problem is made worse. You want plenty of weight on the rear bag but so far I haven't done any tests actually weighing the amount of weight I want on the rear bag. I just do it by 'that feels about right'.

I lift the buttstock at the very rear when feeling the weight bias. If it feels like it is almost teetering on the front rest then I move the forend stop to the rear. Fortunately a 22 isn't likely to recoil off the front bag if you have to move the stop rearward a significant amount.

Strange you should post about your shots always going high. I have been having trouble with my Turbo/Lilja. I’m pretty sure it’s a worn firing pin spring and it’s causing a lot of misfires.

If you imagine our X is .080” on a 25m card. With the crosshairs on dead centre, when a misfire happened the crosshairs jumped up 0.040”, this was with every round. It also jumped 0.020” either to the right or to the left, this was inconsistent i.e. could have been either left or right 0.020 but always up 0.040.

Any thoughts welcome and if anybody has any spare springs I would be most pleased to buy them.
