Hi,
I have a Remington 700 SPS in .223. It had terrible accuracy until I might a Hogue stock and glass bedded it and free floated the barrel. The ammo I have been using is PMC 55grain soft points. At 100 yards they would print about a 2” group before I put the new stock on. I don’t have any solid data on shot farther than that although i think it was around a 10” group at 200 yards. After I put the new stock on and bedded it, the groups have tightened significantly although not enough for coyote hunting which is what it’s for.I’ll see if I can post a picture of my most recent data using 3 different types of ammo that are not the PMC. Anyway, I found that with no matter what kind of ammo( including , Hornady 53 grain Vmax, 55 grain Vmax, and Federal Premium with Nosler Ballistic Tip 55grain), my groups are about 1.23 average. Then they open up to like 3.5” average at 200 yards and either stay the same or tighten up at 300. So why does it have tight groups at 100, get bigger at 200 and then close down at 300. I’m not exactly new to shooting, I’ve pulled a trigger at least 25,000 times with various firearms and air guns. So I’m not sure what the deal is.
