I picked up a semi auto 308 last fall and I've been having some trouble getting it to function reliably. The gun is back at the factory for the second time right now. The problem I'm having is after about 20 or so rounds it turns into a single shot ( FTF, FTE and brass sticks in the chamber ). This brings me to my load development questions. I have been running three different types of ammo, Magtech 150 grn fmj , Remington 150 grn jsp and my hand loads, 147 grn fmj, in LC brass, over 45 grns of Varget. I settled on that charge because I was tring to duplicate the av fps of the factory stuff. The factory ammo is 2,500 fps and my reloads are averaging 2,600 fps ( 16" barrel ). Lymans says, start 42.5 @ 2632 fps and max 47grns @ 2891 fps (24" barrel). The accuracy of my reloads is great. Should I stick with that formula or try something, more / less powerful , in lue of the trouble I'm having with the gun ?
ps I have the same trouble with the factory ammo as with the reloads.
