Im sorry Eric. I sold my match master on the summer of 2013. I have to go build a full size open gun. Shorty is not my kind of open gun
As I said in my previous post, I had to add 1-hole right behind the second side port - both sides. Right at the middle of the comp. They are about 13/64 diameter.
As for the 9mm brass with powder. You will have a compressed load with vv n350. However, for hs-6 and Wac, you will have plenty of room. My load for my 2-9 major open gun are shorter - 1.150 and I dont have a problem with n350, hs-6 and WAC
Cheers
Can you post pictures of the added holes to the T2 Comp? Also, could you snap some photos of the cases after the powder has been added, I would like to see how full your cases are. I will add a picture of my case filled with 7.4 grs of H LongShot that I use for my Steel Master
