Well....it's probably one of the coolest cartridges I have ever worked with. The rifle I have the pleasure of working with has some magical qualities that must have something to do with Mr. Leeper doing the work. One of these qualities is that as long as you use H4831 it shoots wayyyy under MOA, and it actually follows the Nosler manual so accurately it is scary. 120 Btips at 3240fps and 140 Accubonds at 2985fps with SDs under 7fps on every string I have shot with both.
It has superior capacity (slightly but so) than the 6.5-06 and 6.5-284, and given my results (this rifles shoots into 1/2 MOA with a 2.5-8 using ham-handled loads) is easily as accurate as either of the others in a hunting rig. This wonderful example is 7lbs 2oz with the Leupold, talley's, Mr. Leepers special contour 24" Shilen and some few aesthetic pieces of metal removal.
This rig does have a Wyatt CFE box and in recommend it for this cartridge in a Remington or in your case a Winny SA would be perfect Chuck.
I really like 6.5 projectiles, and this ORIGINAL short mag still does it all and now with some pinache due to its history.
Do it Chuck, I'm glad Murray did.
