They had invested a lot of time and effort in designing the polymer tip on the AMAX bullet and knew it was the ideal shape for a projectile's meplat
Semi-wadcutter cast bullets with their sharp edges and flat meplat
have been all the rage for revolvers for the past half century.
It is built off the Sierra 6mm 107 MatchKing, offering a lighter weight alternative, with a long ogive, small meplat
and improved boattail.
There are some good revisions of the classic cup-and-core bullets, which use a sharp polymer tip to avoid meplat
deformation and also give the bullet a good ballistic coefficient.
Assuming the throat diameters are adequate to the bullet diameter below the crimp, the solution is either to properly size the whole cylindrical section of the bullet or change to a design with a smaller meplat
and narrower driving band.
It features a longer ogive, smaller meplat
and improved boat tail to preserve downrange efficiency, enhance accuracy and reduce wind drift.
For bear, I'd go with something hardcast and a wide meplat
The Sabatti is rated for 28,000 CUP so Randy's 420-grain Hardcast with a big meplat
at about 1,750 fps over the chrono in my rifle became my favorite load, and it's well within the capability of the rifle.
The bullet's jacket is scored parallel to the axis on the front half of its length, but the scoring does not extend all the way to the meplat
on the tip.
375 H&H loads--a 270-grain spirepoint, a 300-grain steel-jacketed solid featuring a small flat meplat
and a 300-grain roundnose softpoint.
My SSK double-cavity mold drops 260- and 310-grain bullets, both of truncated-nose form with a large meplat
There was also some information suggesting a big, flat meplat
had a greater wounding potential than the conventional roundnose even if of the same weight.
