Please post a link to your previous mention of the problem. Would be nice to get your gun to work with anything - rather than hunt around for ammunition that works OK in somebody else's gun (a gun which possibly can't be made to choke on anything!) - and which might work worse in yours.
When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind. [Lord Kelvin]
