Never shot this size of hand gun before, have shot a ruger 357 mag 150 grain bullet. what bullet would you recommend to shot with?

SOURCE: Have sighted in a .308 w/150 grain. After

This is a cold barrel warm barrel thing. When cold she shoots dead on. Try to space out you pratice to keep the barrel cool. When the gun warms up things do expand and it can cause the reciver to bind the scope. Also can cause the barrel bore to increse and let gases by pass the bullet causing lower exit speed of the round.

SOURCE: I got in a tight spot needing a scope last season.

well one day you may lurn that cheap is cheap! and tasco is rubbish cheap! i would say without dought the cross hair in the scope has shaken apart,,,due to recoil,,,a 30-06 has a big recoil
try holding the rifle stock on your jaw and firing the rifle off?
when or if,, you wake up in hospital with a shaterd jaw and with no teeth left in it you will know then! and cheap tasco scope is an air rifle scope it cant take 2500ft/lbs of recoil???
so it wont take much of a kick to mess it up,,
i put one on a 303 enfield??? i got 3 shots before it fell to bits!
if your going to buy cheap scope's go for nicon gold crown?

SOURCE: scope wont track tried to shoot a square test and

some scope wont do a square shot test,,but dont worry to much about this,, just clamp the rifle down and zero your scope ,,you get it dead on the rifle needs to be clamped down and not hand held
