So far my build just a Savage Model 12 28 inch Criterion bull barrel 7 twist loves Berger vld 115 and Nosler 115 rdf and 115 dtac. During testing the vlds impacted 1 and 1/2 inch to the right and the rdf 1 inch to the right. Just at 100 yards so far. Did not chronograph because cloudy conditions. Should be around 2950 muzzle velocity Hornady brass h4350 CCI benchrest primers 20 tho jump. 3/8 to 1/4" 4 shot group . I shoot one shot to settle the bag. My bag is pretty much crap I use playground sand I need to get some good stuff and learn how to settle the bag. I've seen benchrest guys hit their stock a few times with they're fist. I still think I would still shoot a couple on it to really get the bag settled I use the Harris bipod and rear protector bag just thought I'd throw that out there
