That's impressive penetration. What velocity? Here's a .416 400gr CPS that broke both shoulders on the big bull ele in Oct...Rigby velocities...2350-2400.
I've never heard of any bullet doing that. I broke both shoulders on a large bull ele with a .416 Rigby solid late last season...but I didn't get an exit. That's a LOT less than end to end and I think you would be hard pressed to get a lot more penetration than a premium .416 solid gives you.
More ejecta (powder weight) definitely increases recoil. The calculator includes that variable. With my big bores I try to run loads in the middle of the pack for less recoil but good velocity. A good example of ejecta affecting recoil is in running numbers for black powder loads versus nitro...
Recoil can be calculated...felt recoil is extremely subjective. I don't think there's much difference in the numbers above but they are offered to show how close the two examples are. Felt recoil would be related to gun fit and stock design and as mentioned, some powders seem to generate more...
Recoil is somewhat different unless you play with it to make it similar. If you keep the gun weight the same at 10 lbs and run some standard loads, here are the numbers...
Here's a typical .416 Rigby load by the numbers...
And the 458 Lott at the same gun weight but with a typical Lott...
The old Ruger tang safety in .458 was my first big bore. They are slick rifles and I liked mine a lot. I prefer the older tang safety rifles to the newer models. Those barrels are beefy!
I haven't found an early Rigby yet. In the meantime, I have an awesome Dakota .416 Rigby that is accurate and beautiful...not a thing wrong with it, except it's not a Rigby. First world problem for sure and if that never changes, I'm ok with it.
My DG scopes are all 1-6 or 1-8x. All have illuminated reticles that on low power are the same as a red dot. Honestly, I don't need anything else for any of the DG and PG that I hunt. There might be a few exceptions out there...vaal rhebok or mountain nyala...speciality hunts. I've never...
JJ says it was designed for mag cartridges. There were a few made on 270/280 standard length. One large in 505 Gibbs and two in .222 along with a prototype single shot .222.
