Paper patch template

[powderburner]

do you just want a flat with an angle or do you want a finished template .I do not have a 446 bullet . but I will cut you a piece any length you want, just let me know.

just as an aside , you might try your 44 patches , at 8 tho difference the gap may be neglagable ,
my 44 and 45 patches are basicly the same length
