I agree get as many brands of ammo you can even different grain bullets by the same company 30 vs 40-- 40vs 50 ect and try them all. then you will know what your gun likes best keep a record of what you shoot and if you cannot find the best brand it likes you can get the next best ect. My gun shoots PMC predators real well, cheap end of the line $5.29 a box and also likes Remington Premium at $ 11 plus bucks a box. I have not tried any Win or CCI yet will try that next. Federal in my gun shot good but in a diagional string but all connecting so it was not too bad. I can only say as the rest will with a 22 mag or LR you have to try them all as far as ammo goes. Jim
