Many gun marketers have been touting the capability of using 150-grain powder charges and enhancing velocities in excess of 2,200 feet per second. If groups are wider with the above loads, reduce powder charge by 5- to 10 grains. This will place my impact in the 6-inch kill zone out to 150 yards.Īn accurate rifle-bullet-powder combination will easily shoot 1-inch groups at 50 yards and 3-inch groups at 100. For long-range hunting opportunities, I sight my in-line guns for impact 2 inches above the bull’s-eye at 100 yards. This will put me in the 6-inch kill zone out to 120 yards. I sight-in any muzzleloader at 50 yards, trying to impact 3 inches above the bull’s-eye. 54-caliber sabots, conicals (try 425-grain bullets) and patched round balls with equal accuracy. An 85- to 100-grain charge will effectively shoot. 54-caliber muzzleloader is almost universally manufactured with a 1-48 twist, although I have a still-serviceable 35-year-old side hammer gun in that caliber with a 1-turn-in-72 twist rate, which was good for patched round balls only. 50-caliber muzzleloader with a 1-32 to 1-38 twist rate should do well with the same sabots and conicals with a propellant charge in the 85- to 90-grain range.Ī modern. Conicals in the 300- to 385-grain range typically do very well with a similar powder charge.Ī. Most in-lines and replica hunters are now shot at pre-set propellant levels with preferred projectiles and the sights are adjusted to set the impact point.Ī large part of the reason for the change is the development of popular pellets (Pyrodex was first) manufactured in 50-, 30- and 20-grain capsule units.įor whitetail deer hunting, in-lines with a 1-turn-in-24 inches to 1-28 twist will deliver excellent performance with a 100-grain propellant charge and sabots in the 250- to 300-grain range. Bryan Oliver – Quick Hits, Videos, Memesįor years it was recommended that shooters “work up a load” by starting at a low powder charge and increasing it in small increments until the gun shot its best group.Babe Winkleman – Good Fishing / Outdoor Secrets.Eddie Claypool – Blue Collar Bowhunting.If the hole spacing is different, then for model 70 use 47+ 46 and for model 70 use 49A+ 46. If the hole spacing is the same, then for model 52 use 46+ 46 and for model 52 use 25+ 57. Note: The handiest way to pinpoint the correct base for the Winchester 52 & Winchester 70 Long Action rifles is to check the spacing of the tapped holes for the rear base and compare it to the hole spacing for the front base. Note: The Winchester 52 with the same hole spacing may require bolt and/or safety alterations to function safely and properly. The rear base may require modifications for correct fit to military actions. Note: For 1.4" diameter Mauser Receiver Ring 98FN and 1.3" diameter Receiver Ring (Swedish 96) shimming is probably required for perfect scope alignment. Note: For Savage / Stevens 200 with shorter tube scopes or red dot scopes use #402 extension front base or one-piece base if available.
