[4fifty8]

• Speer 350gr Mag Tip / 2.8cc~36.5gr Alliant 2400+polyfil / 9-1/2 M
• could likely shrink group size by adjusting powder charge
• previously developed hunting load 300gr TSX @ 3000 fps mv
• ---------------
• 41 cal Speer 220gr with tape patch increase dia. to ~.416"
• 2.8cc~23gr Herco / 9-1/2 M
• cheap plinker grouped better after several fouling shots
• ---------------
• ***these loads safe in my rifle ONLY non-published loads NOT recommendations***
• less powder / less recoil / less wear / more target shooting

How much of a step up in recoil is the 416 Weatherby over the Rigby when talking factory ammo?

Step down way down in recoil with the Mark V's excellent muzzle brake with full on loads kicks like my .30-06. https://www.youtube.com/shorts/6Pp-SITHD2Q

• Alliant 2400 charge increased to 39.0 gr(+polyfil) groups tighter
• zeroed for 300gr TSX @ 3000 fps mv, aim with 3x 6 o'clock post ok off-hand at close range
• non-published loads - NOT recommendations - safe in my rifle ONLY
