A lot depends on the platform and weight of the gun. Never fired the .416 or .470. But by your scale. The .375 about a 6, the 9.3x62 a 3.5, the .300 WM a 4, the .450-400 (Ruger No.1) a 7. I have fired the .458 Win and give it a 8.5 with full power loads.
I would add my .404 Jeff to the list at about a 6.5 (CZ 550 at 10#).
From my experience shooting both the .375 and .416, the Rigby is not quite double. Mine is a CZ550 and with the 400gr at 2350, it is around 58ft/lbs. I owned a Ruger #1 some years ago that felt much worse.
Per canuck416 statement. I too found that the Ruger No. 1 rifle in the heavy hitters seems to kick harder than similar weight rifles of different style like a bolt gun. I dont know why this should be other than the wimpy pads they use. I love the style of the No.1 stock and they have a good length of pull and fit me well but are not fun to shoot in the big bores.
I have shot back to back on my last trip my light weight 9.3x62 and Chris Troskies factory Ruger 77 .375H&H. Recoil was almost identical with the .375H&H marginally 'heavier'. I believe he was shooting lighter weight X bullets in it.
I was surprised as I expected the .375 to have more.
I also own a factory CZ .416 Rigby and to me it is easily double+ that .375 H&H.
Nsok, to show just how subjective FELT recoil can be, coupled with the effect of being fired from different platforms (remember, these are my personal impressions of recoil based on rifles I have/do own, and others I have fired);
1) I find any of the three different 458 Lotts I have owned to be more comfortable (easier on the shoulder) than any 416 Rigby I have ever fired (full power 416 loads come back much faster than the Lott which is more of a heavy push, than a fast kick)
2) several different 470 Nitro doubles I have fired to be slightly more comfortable (easier on the shoulder) than my full power loads in my Lotts (most of the double 470's I have fired have been very generously weighted at 10lbs and more).
3) my light-weight Rem 700 mountain rifle in .375 H&H extremely comfortable to shoot, more so than a CZ 550 I have in the same calibre that weighs more than a pound heavier (the stock shape and dimentions of my Rem are ideal for me as compared the the Cz stock).
4) most .375's to have been more comfortable (easier to manage) to fire than the, two only, .300 Wby's I have ever fired.
5) have noticed a trend of felt recoil, (on me at least), that cartridges with sharp shoulders, e.g the Wby range, will tend to produce more felt recoil than counterpart tapering rounds. Personally, I find it easier to manage the recoild from a well stocked .338 than firing a .300 Wby.
From my personal perspective, the main factors which appear to have major bearing on the level of "recoil-impact" on me when firing;
* projectile weight X velocity
* stock fit/configuration
* muzzle blast
For me personally, (I have substantial hearing loss, a direct result of exposure to repeated muzzle blast) I experience some 1/3 less (as close as I can judge) actual felt recoil when using hearing protection as opposed to when not.
Proper stock fit and familiarity will go a long way to "taming" felt recoil in big bores but I concede that we all have our individual limits.
I guess I was fortunate, in a way, to have grown up as a young lad accustomed to firing great volumes of 12g rounds at frequent intervals.
These days, after having fired many hundreds of rounds of 458 Lott ammo in the field and over the bench that, for me, knuckling down on the bench with my favourite .375 has become rather mundane and uneventful.
I conceed that there will be many that dissagree with my "perspectives" as I see many different hunters in the field each year, of different shapes and sizes, firing different rifles, all essentially chambered in the same range of big bores, .375, 450/400, 404, 416, 458, 500 and most all displaying different levels of managability and control over the recoil produced in those rifles.
Not much help to you I realise, as I understand from your post you are trying to gauge your ability to cope with the level of cartridge you intend buying.
My suggestion would be to try and find the best fitting rifle in that cartridge, find someone who owns one and test fire it (with moderate loads) off-hand, or from shooting sticks whilst wearing proper hearing protection. If you find that you are able to have some reasonable level of managability, understand that altering the stock of your chosen rifle to best suit your fit, and plenty of familiarity with that rifle will eventually lead to dampening the effects of that recoil.
Also remember this, we have a higher portion of one shot kills on buffalo from hunters placing their first shot well with a comfortable .375 than with all the other cartridges combined !
Sorry for the long winded reply but recoil is a constant factor in my life for both myself and my clients, and although I am aware of, and acknowledge, that not everyone will ever be comfortable with the likes of a 458 Lott or a .500 nitro I believe there is a lot of "whooey" out there written about recoil that prevents some hunters from ever realising the wonderful benefits provided by some of these cartridges when the correct procedures of rifle fit and familiarisation have been addressed.
Thanks Paul for your post! Write as long and often as possible...we love your posts.
I agree 100 percent with your post, proper rifle fits helps so much it is hard to underestimate it's effect. And I agree with you, some cartridges by design (Weatherby) are rougher on the body than others. I would not be afraid to shoot any of the big bores at a paper target as long as the gun had a good recoil pad on...and I think that is a good way to see if a gun is too big for you.
My 500 Jeffery shooting 570g TSXs at 2410 fps is double the recoil of a 375 H&H shooting 300g bullets at 2550. I'm assuming an 8.5 lb 375 H&H and a 10.25 lb 500 Jeffery, both weighed without scope, sling or ammo. I have both, so I can't imagine a 416 Rigby or 470 NE kicks as much as my 500 Jeffery unless they are very very light. Of course, if the 375 H&H is at the top end of your recoil tolerance (no issue with that), than a 416 Rigby might seem like it has twice the recoil. Here's a link to recoil calculator online that I like a lot...
Mmmh, this is not exactly a fair discussion. I shoot a number of medium to large calibres. My favourite all rounder is a Ruger M77 in 338WM. I would rate the recoil as a bit more than a 30-06. Belts a bit on the bench but not noticeable in the field. My 458WM ( custom stocked CZ) is more energetic and not fun to shoot off the bench but also not really noticeable in the field. Most doubles are OK provided LOP is about right as combined weight of 2 barrels absorbs quite a bit of energy, however a lot depends on fit and weight. One of the worst rifles I have ever shit off the bench was a CZ. 375H&H. The standard cz stock is a bit too long for me and the combination of drop and butt plate angle make it rotate sharply upward, so smacking you in the face. This is quote easily cured, resulting in more of a push.
My 416 has a straight comb like the Rigby and Ruger. Recoil is sharp but not terrible.
Agree with what several others have already said..
There is no way to really fairly compare, unless you were talking the exact same rifle, same stock profile, same recoil pad, same weight, same balance point, etc..etc.. across all calibers considered..
For example, the hardest recoiling rifle I have ever owned was a .300WM.. While my .375 H&H certainly generates more energy, its several pounds heavier than the old 300WM "mountain" rifle I used to own, has a much better recoil pad, is better balanced, and the stock fits me much better.. I can easily shoot a dozen or so 300gr rounds off the bench with my 375 without it bothering me... my 300WM was a very different story though.. at best I wanted to shoot a 3 round group, and then I would set it aside for a little while before picking it back up again.. there was absolutely ZERO things pleasurable about shooting that rifle other than the tiny little group it could produce out to a few hundred yards..
I had a little 7lb, compact .45-70 at one point that would rock you when you squeezed the trigger on a 300gr projectile.. but it was honestly just a good hard "shove" as opposed to a "kick".. whereas I have a 7mm WSM that definitely is all "kick" and no "shove" when I light one off.. and is a whole lot less pleasant to shoot.. and it weighs a full 20oz more than the .45-70 did..
Mule deer and Colorado elk seasons almost done! Hunters driving farm roads, looking for racks, their PH driving them along, I ask that you not pull into my drive. The buck behind me, on the boundary line of the GMU somehow knows. The hunter laughs, I would invite you in to see my Searcy rifles but social distancing prevails, darkness arrives and the buck slides away into secret tree grove...
