Re: Michael Fell PH on the .458 Winchester Magnum

Can't help but feel the lack of straight penetration being likely due to poorer constructed solids rather than the 14",and 15" ROTs normal for the calibre these days.
Seems to me the 9.3's having 14"ROTs shoot SD bullets of over .300 just fine.
Now, with the older normal slower twists in .458 cal. of 18" to 22", I can understand where a faster twist (14" or 15") might be advisable, but not faster than that in duchess a larger calibre.




I had the same view Daryl!
If stability was an issue then the bullets themselves would be keyholing in regards to barrel twist rate. It has been a known issue since dot that Taylor brought up of solids fishtailing & going off course - this is a bullet construction issue only!
Yes monolithics are longer due to their lower sectional density, however due to they physical construction they have a better penetration ability - well those like the Woodleighs anyway!
The buffalo bore monos I have no experience with, but i have no doubt are certainly up to the job, they should be designed to SAAMI specs, so they should get a bit more velocity being lighter than nominal 500gn pills the .458WM uses, new powders since 1956 have helped in this regard to get it closer to the old 450 Nitro.
Not sure if these buffalo bore bullets are full groove sized projectiles or they have driving bands?
As far as running these in ANY double, I wouldn't use any monos without driving bands to potentially avoid any overloading of the action!
Nice Elle in the post, & if I'm not mistaken I saw a Woodleigh Hydro dressed up in one of the nickel cases!
