It's really not bad.
Winchester and Federal 300 grain JHP are "pooty-tats".
Remington 405 gr JSP are downright mild.
I've never compared them to any other caliber, but, IF I had to compare the above, I'd say equal recoil to a .308.
Now, I've done a LOT of reading on handloads, and from what "I" have found out, Reloader 7 gives the best velocity with lower pressures than other comparable powders.
IMR 3031 is supposed to be good, and I bought some to try.
However, loading a Cast Performance 405 gr LWNGC boolit, with 40.0 grains of RL-7, I get FANTASTIC groups at 100 yards, and about 1660 fps, with very tolerable recoil.
Now, step up to 42.5 grains, and after FIVE rounds of that load, "I" have had enough for one session.
44.0 grains is brutal on this old, gray-haired guy. (Max load, btw!!)
I know guys that shoot small loads of Trailboss and a 405 grain lead bullet, and are getting cloverleafs at 100 yards.
I know others that are loading Alliant 2400 (bunny-fart loads) and filling the case with "Cream of Wheat" and SMACKING a 24" (4" thick) steel gong at 200 yards. A distinct "THUH-WAP" from the lead flatpoint hitting that gong brings a smile to your face.
Honestly, I think that IF I had to choose just one caliber/cartridge for a rifle, I would walk toward the .45-70.
I like it THAT much!
ETA: Full disclosure - I did put a Limbsaver pad on my 1895G. The factory pad was as soft as a brick, and since I broke my neck (2001) I didn't want to really jar myself with some warm(er) loads.
