I bought a LH 457 Varmint a couple months ago. Fantastic rifle! I still need to take the barrel off of it and thread it for my tuner and suppressor to go on it. I installed a different trigger spring and a stainless steel trigger pin, the trigger is now set at 10 ounces. Installed an Area 419 30moa scope rail, and an Arken EP5 5-25x56 scope.
So far this rifle really likes Wolf match ammo. I want to try some SK ammo but just haven't bought any yet.
Just for giggles, I put one of those Limbsaver rubber barrel tuners on it. These things actually work!





Without the tuner on the barrel, it shot like this at 50 yards- around 3/4"



With the tuner, at 50 yards - around 3/8" and even better if I didn't screw the second group up with one shot.
