I shoot a Remington 700 20" brl 1-12 twist 168 gr Sierra HPBT bullet, Started out as a 700 LTR. barrel & action same as the SPS,After 4000+ rounds through the barrel had a barrel change. 20" heavy barrel has less wip then the 26" I bench rest shoot with this rifle 200 yard zero 1/2" groups an better with a rear bag off a Harris bi-pod. Just love shooting the rifle. Changed the trigger to a Jewell set at 10 oz. I favor the 20" over the 26. 1-12 has less stress on the bullet, perfect for 168 & 175. Sierra came out with a 168 grain tipped match king bullet good for 1000 yards if long range is your game. 200 yards is my range, goal is 1 hole 5 shot groups, close but not there yet. If rifle is for bench only, once you get use to the rifle ( alot of trigger time) changes will come, Bedding the stock or change, trigger to a much lighter pull & after 4000+ when barrel change is needed have it blueprinted, I can tell you I can not be more satisfied with my 20" barreled Remington 700 308 Cal. 1-12 twist. Hope I helped, Chris
