I have a 375H&H in a Rem 700 SPS about 7lb of weight and felt recoil is way less then the CZ550 at 2 and a bit pound heavier. The synthetic stock absorbs a lot of recoil. Break is a pain to all others and your ears. I had a moronic idiot next to me on the range firing an 20" barreled 375H&H with a break. When he fired I had anything loose on my bench blown off/over, including my spotting scope. Also it gave a reading on my chrony, don't know if this was from the blast or the unburnt powder granules going through it. Yes there was unburnt powder as I was hit with it and found plenty on my bench.

You wont have unburnt powder but you will have plenty of blast noise and concussion.
