I also have an A7 and I love the gun. I also have Talley mounts but I put a Bushnell 3200 3-10x40 SA short action scope on the rifle. Mine is a
. With 150 gr. or heavier bullets loaded close to max the rifle is a pretty good kicker. I cut the stock off about 1/4 in. and installed a limbsaver recoil pad. Less felt recoil eliminated the occasional flyer. [better accuracy]
The only other thing I could see to do to help accuracy was to glass bed the
aluminum plate so it will not move any. note: did not take much bedding compound..
The loads I use are: Hornady bullets or Barnes bullets,, RL-17 powder,,
Federal large rifle BR primers,,Federal cases.
The rifle has never shot a 3 shot group over an inch with any load!
But after the recoil pad and bedding the recoil plate,, the first 2 groups--3 shots each,, one was .5 and the next group was .6,,, 2 different loads
The rifle is light, has a great trigger, and shoots just about everything good.
Those 2 things might help accuracy, sorry I was so long winded.
