If you want a 375 I honestly don't think you need to test fire to see if recoil is OK....unless you already fid a 308 as being heavy going.

In my opinion the 308-30/06 and 375 are in the same general recoil braket and with the 308 and 30/06 being at the botto and the 375 at the top.

There seems to be threasholds at work. For example the 243 recoil fels like zero compared to a 308 or 30/06. If instead of a 375 you were looking at the various 416s and 45s then they are a big jump from a 375, almost like the 243 to the 308.
Just bear in mind that a375 is only medium power calibre and likewise the recoil is only in the middle of the sprectrum.many shooters do all theior shooting with the 375.

Just buy one
