I would appreciate thoughts and opinions on Remington 700 aac-sd in 6.5 Creedmoor. Bought this gun and can barely squeeze out 3/4 in” groups at 100 yards with rest and rear bags. It’s got a bell and Carlson medilist stock leupold mk4 6.5-20 ffp with tmr retical and 20 moa base. I’ve owned 700s since I was 14 and that was in that was a long time ago and have never had a problem with accuracy. I worked my loads up to 41.5 grns of h4350 and got about 5/8 of an inch. My 700 308 and 22-250 shoot 1/2 to 1/4 all day long. Am seating 142 smk 2.805 col. am long in the tooth but on good days can still shoot a fair group Have not cronoed this load but seems too be the best this rifle is going to get. Have not shot past 100 yards and have 100 rounds down range. Any thoughts I would appreciate as at 65 am still learning. I’ve loaded 140 smks 140 eldx and 140 barns match. 142 smks were most accurate as. I thought they would be Thanks
