We´re mid season around here, but due Covid.. yadda yadda..
This year we opted, me and team mate, to campaign a French made ML. A Felix Escoffier, which is a 45cal gun running a 1:21 twist.
Issues we´ve run into though is that the rifling is very very deep which i believe we came to terms with with the "new" boolit. A greaser.

This i designed for "short range" work, with a total length of 32.2mm. Ogive came to due a lot of playing around with basically the Postell base design, and evolved from there.
This boolit has proven to be fairly along the lines what we need (50m standing and 100m prone) and we´re currently developing load data for it for the given rifle at hand.
Shorter boolit for short range, and if my math is right this thing is stable to approx 850fps. We normally exit between 1200 and 1400 though, depending on intended use.
That said i´m giving thought to cutting yet another mold, flat sided and intended to wrap of basically the same proportions, just modified in diameter to take the paper into account.
No matter if a greaser or PP it will be used with a greased 45cal wad, this to ensure sealing due that overly deep rifling.
Any thoughts on the matter?
We CNC cut our own molds so in essence, anything goes.
The greaser, FWIW, comes in around the 420 mark. We´ve also produced a 36mm version for it, that comes all in at 500 (greaser too).

Here team mate Patric going at it.. Very lightweight rifle (2,5kg aka approx shy of 6lbs) which of course shows as loads increase.
We´ve tried it with different designs, backed at most by 110grains of powder, and she´s rather picky about what she likes.
