i have a bone stock 7mm br. i have taken 5 cow elk and mule deer with it. it has a 4x leupold pistol scope on it. it has shot sub moa, and i am sure with some effort would shoot one hole. i just shot it last weekend as i am taking it to minnesota to hunt deer this weekend. i shot 5 3 shot groups that are right around 1" with no effort at all.
the 7mmbr is probably not the best choice for varmints, but it does a number on elk, 3 of the 5 dropped in their tracks the other 2 went less than 75 yards with 130gr sierra specialty pistol bullets. all the shots but one were very well placed.
mine is a mid-grip, plastic stock, 15-3/8" barrel single shot. i have fancied a smaller bore custom one for years, one of these days i will get one. probably a 223 with nice wood.
i was given a check by my dad for christmas back in about 1991, i spent it all on my xp-100. i have never changed the setup since. great gun.
