http://frontiermuzzleloadin.powergui...-accura-part-2 Here is a perfect example of design dictating weight. the PT gold to the right is the heaviest bullet of the 3 in the picture and there accurate. even thought these are .45 cal bullet, the same design applies to the .40 cal lead/jacketed bullets.PR has 2 designs that work and are different although there not a plated bullet, they could easily be.the bottom line is work with what your dealt with which is a 1:30 twist and it's a whole lot easier to have someone design bullet or 2, than trying to sell a M/L in a twist with a bad rap,even though it's not deserved.it appears Knight also felt this way..doing this would make a whole lot of .45 cal shooters happy and further the sales of the .45 cal, for not much investment
it's a no brainer in my book.
