Probably 99% of the guys on here will say no but that doesn't mean recoil does not affect their shooting. I know a few guys who acquired .300 magnums for hunting and developed a pretty substantial flinch. The guns were either too light or poorly stocked for their build. Plus they did not practice enough pre season to master the rifle. These same lads did not think of recoil when shooting at game per see but their subconcious mind certainly did, they shot poorly. All the power in the world does no good if the bullet hits in the wrong place or not at all. A friend of mine has quite a selection of rifles; 7mm magnum, .300 magnum, .30/06 and the like but he claimed the most unpleasant rifle to fire off a bench that he has owned was a pre 64 model 70 Winchester chambered in .257 Roberts!! The rifle weighed around 9 lbs. scoped and loaded and the Roberts is a mild round even handloaded but for whatever reason it kicked like a mule so much so he sold it cheap. I have always wondered if it had an undersize bore or something.
