Hi I'm just starting to load up a few 308 rounds with 9g of trailboss behind a 165 hp, I see on other pages that some recommend drilling out the primer flash hole with 3.5 mm drill,
Any one doing this ?
Ive loaded 303 and 44mag subs but never drilled out the hole. I can see the theory behind it.
It would be great to hear what others have got good results from. Cheers
