quas: re: the scope of your choice and the different points of impact of the hunting bullet and the practice load. Get the scope of your choice and mount it to the rifle; sight it in for your hunting loads. See what the point of impact is for your plinking loads in relation to that for your hunting loads; do not adjust your scope for the plinking loads, just take a different point of aim to bring your point of impact wot where you want it.
Here's a example for me: I shoot a Winchester 94 AE in 444 Marlin. My scope is adjusted to point of impact at 100m with heavy slugs (300 gn at about 2200'/sec.). When I plink with cast 240s and pistol powder charges, my point of impact drops a good bit at 50 yds, which is what I plink at with that rifle. It would drive me nutz adjusting the scope for that but I noticed that the point of impact at 50 yds showed on the scope at right around the junction of the fine cross-hair and the thicker post coming up from the bottom of the scope, so I use the apex of the thicker post as my cross-hair and thaat seems to work for me.
I have also used 7.65 Luger and a 7.62 Tokarev chamber adapters in my 30-06 with those 93 and 85 gn bullets impacrting in a much different place than my usual 180 gn hunting loads but at plinking/garden pest ranges I just use the apex of the thick bottom post of the scope as the aiming point and so far, mister wabbit has not gotten to the carrots.................hth.
