young gun that's one hell of a price for a strikerfire. the best i ever seen for that model was 329. & no i never experienced a problem with scope rail mounts matching holes they all have lined up to the 4 holes drilled & tapped . i have used 2 different scope rails both made by traditions the black scope rail mount only is part number a1780 & a coma combination base & ring set # a1788rb the base only was less than 10 dollars & the camo kit was around 25 . i own a striker fire ldr long distance rifle & i shoot blackhorn 209 using 110 grains & a strikerfire 28" barrel & use 100 grains of bh209 both shoot great & burn the powder completely. i've shoot it from a bench with snow on the ground & off the bench there is no power laying in the snow . it'sa test to see how much unburned powder there is . love both of my strikerfires. they have a great trigger set to a little over 2 lbs
