No problem - I swear by it!
Takes a bit of working with it to get it tuned well. I highly recommend having a gunsmith install it in the forestock.
Once installed be prepared to go through 500+ rounds firing from bench. Use your hunting ammo, not your practice ammo. Different ammo will make a difference. The down side for me is that my hunting ammo is match grade and costs nearly a buck per shot.
After tuning twice I would make the following recommendation. First screw the block in as far as it will travel (don't force) in one direction. Then screw it as far as it will go the other direction, counting the number of turns. Start a chart with the left hand side recording the block position by turn(s) and the right hand side recording the MOA (a good caliper helps). Each chart entry should be measured in whole turns.
Once you have the lowest MOA per whole turn, then try adjusting by 1/4 turns off from the full turn using another chart. This will help find the sweet spot as rapidly as possible - especial the second time you go to do this. This is something I did not do and wish I had.
If you hand load, get a consistant load worked up, work with it till you get the smallest group possible, and then make MINOR adjustments in your loads. You might even be able to get that .08 MOA.
Good luck!
