Following some advices I read in the FAQs, that sometimes pressision could be afected by the forend. I removed it and the very same loads that grouped 4´at 150 mts, spread to 8´after I removed it.
I guess that pressision issues regarding my .308 H&R seldomly can be linked to the handload. The very same recipe (45 grains R15 and 165 grains Speer hot cor) I use for my Remington Seven .308, and that my father and brother also shoot in their Ruger 77 and Sabatti arms either, groups not wider than 1,5´at that distance. then, I can´t understand why my .308 H&R spreads that much. I tested other recipes, all with the same not-so-good results. I know I cannot ask that much out of this low budget rifle. I bought it as a non bulky replacement rifle if something happens to my other rifle during a boar hunt, but at least I´d like to shot groups about 2,5´at 150 mts.
If someone can give an idea regarding other experiments, I´ll be very thankfull.
