Back to the original question - I have never shot or hunted with a 700NE. But I have used all the rest. Biggest disappointment was an unfired 500J made by Harald Wolf . I was test firing to buy - it jammed . Eventually got it shooting . No doubt a great cartridge but passed on the rifle . Can’t really say 505 Gibbs or 500NE are better than each other . Depends if you want a bolt or double . Own one of each and love them . Use here in OZ on buff - very effective . Not sure why some are down on 577 and 600 NE they are amazing cartridges . Key with 600 is it needs to be doing circa 2000fps . Own one and love it but would love a 577 too . Have hunted with both and they are brilliant . Recoil not bad . Love the 375 H&H but the big boys really are great .
Harald Wolf was regrettably not always successful with his rifles, but we want to let him rest in peace.
As far as weapons with a caliber over 50 are concerned, the bolt action rifles caliber 500 Jeffery and 505 Gibbs are still about good to handle, or perhaps the DR caliber 500 Nitro Express. We are not talking about recoil which is present in all weapons of these calibers and should no longer be a topic in such discussions. A problem is but the handling of the heavy rifles caliber 577 Nitro Express and 600 Nitro Express, especially the weight of the barrels which makes such weapons among other things tip-heavy. Nowadays imho such weapons are not suitable for a client that does not have to do a backup. By the way, for the latter, other weapons also do the job well.
