RE: What makes the 7400 SO in accurate?
I've seen hundreds of these rifles and maybe a few of them out of the bunch that will hold its poi after 3 or 4 shots.
Let me explain....
Every year I work at a large gun club for a couple of weekends before deer season doing a deer rifle sight in clinic. In my neck of the woods, 7400s and 742 are probably the second if not first most popular rifle. What we do is have the customer take 3 shots, to get a rough idea where its shooting (I'd say 85% of those that show up are not good shooters, its not a criticism, just a fact) I help them adjust their scope or sights to zero it at 100 yards. The next shot will usually be close to being zeroed, then the next shot will invariably be 5 or 6 " away. At this point, if you don't let the rifle cool down for 10 minutes, the shooter and I will be chasing our tails as the rifle/shooter combination will go from a 3 moa combination to barely being able to shoot pie plate sized groups. You let the rifle cool down for 10 minutes and it settles back down. If the shooter is a good shot and puts his first 2 shots close to eachother, the sights can be adjusted and the next couple of shots will usually fall where they should.
The remington semiautos are decent hunting rifles- they will shoot to poa if sighted in correctly and are good for a couple of shots which is all you really need for hunting purposes, but shooting more than a few shots accurately can be an execise in frustration.Most pump and semiauto shotguns do the same thing, while the mossberg bolt action slug guns tend to be much more stabil. From the handful of BARs I've seen, Brownings don't seem to have this problem.
