I've got two. One in .300, and one in .35.
Now, on the one hand, I didn't find the recoil of either gun to be at all prohibitive. A bit odd, perhaps. Downright confusingly un-natural-feeling, actually, if you can seperate out the various bits of the cycle:
The action spreads the recoil impulse out over a relatively long time period, and at the end of the recoil stroke after cocking the hammer, the barrel-bolt unit gets caught and has it's motion stopped by a SUBSTANTIAL buffer spring, whereupon the barrel unlocks from the bolt and returns forward, extracting and ejecting the case before finally tripping the release on the bolt which is driven forward, stripping the next round out of the mag, chambering it and then locking the bolthead to the end of the barrel. The barrel-return/recoil spring would do credit to a garage door, and when the barrel stops it's forward motion against the inside of the barrel shroud, you get a bit of forward recoil impulse.
All-in-all, quite a complex bunch of activity, involving a couple of substantial masses moving back and forth at different times between three different heavy springs, all in a fraction of a second. "Frenetic" comes to mind.
But like I said, the primary impulse is spread out from here to Timbuktu, and handed to all these different partiscipants. To ME, it seems to be totally reasonable. Nicer than the belt I get from a standing-breech gun firing a comparable cartridge, I think.
But that's just MY impression. I'm a well-known recoil abuser, and my standards are to be viewed with suspicion. Witness the username, and know that I spent way too much money custom-ordering a derringer chambered in 7.62 x 39 that is known as The Monster, and I didn't name it.
Therefore, on the other hand, there are a few well-experienced shooters on this board who have purchased Remington Model 8's identical to mine, who report the recoil of the M-8 to being comparable to being slugged by a bus full of fat kids on their way to Camp Stomache-Staples for a little intensive attention. (My words.)
I exagerrate a little, but the report stands. Other reputable folks (More than one, mind you.) have reported that they are surprised at the strength of the recoil of these guns, even in the context of their not insubstantial weight.
So while I'll still say it ain't all that bad, I'd be inclined to think that H_R_G is a friggin' loon just like he says he is, and his standards are from some alternate reality where getting your clavicle chiropractically re-adjusted by a steel buttplate is somehow equal to the delicate touch of a falling snowflake, which is substantialy incorrect.
That aside, it's a stout shove that won't bust you in the chops or give you a scope cut, but it definitely is no love tap. Brace for it, so it doesn't surprise you.
