Tuning FFX Impact M3 35 Cal beat slug Dia

[smokeOnBro55]

for those of you with the Impact M3 35 cal what slug dia are you finding the best accuracy with 356.357 or 358 or ?

I hand cast my own slugs ....just trying to get a head start if I need to order a different sizer than I have now 

Thanks

Why don't you slug the barrel then measure what comes out and add .001 to find your sweet spot.

I was going to do that WHEN it arrives.

Was hoping in a few posts would see a defined pattern on size required and if I did not have that sizer get it ordered.thus cutting own the wait time to shoot
