With 4 holes you will probably need 9.9-10gr. to get pf. I use Lee dies, no problem. I use a u die, as was recommended here. I have found some range brass that would not case gauge in my hundo even after the u die so I now roll size as well.

3.0gr with hi-tek coated 160gr was 138pf in a Gen5 34. I'd start about 2.7 or 2.8. Sorry, this was for 9mm

Generally if they fire on second strike the primers are not seated fully.

Shot over 10k of the green and yellow box Servicios with no failures. Friend of mine has shot over 20k of the white box variants with only a couple light strikes in a Glock.

Agreed

Pretty sure Tyler uses Xtreme 165s. 2.7gr of N320 made 131 in my Tanfo S3 when I tried them.

Jeff just did the same for my Bul

You'll have to get rid of the brass stringers in the die by using a .223 copper bore brush wrapped with a grey scotch brite pad. Put the brush in a drill and run it untill it builds up heat in the die. Then only use a lanolin based lube or it will do it again. Redding performs as well without all the additional steps.

I just use Ginex SPP, Servicios SPP and CCI SPP and do see a lot of yellow corn meal in the barrel but it hasn't caused any problems. I have some magnums, I might try them to see if there is a difference.

This was 9.8 AA7 124PDV2 @1.170. This ammo at Nationals in my Bul with 2 3/16 holes was 171. I would not shoot a level 2 or higher with this load in the MPA, would bump up .1 or so but it's fine for locals.

I have a MPA DS9 with nine holes and it makes 167 power factor with 9.8 AA7 and 124PDV2 bullet. I don't know how they do it but their barrels are fast.

1.165

Bul 5" with 2 3/16 holes, 10.4 AA7 with Berry's 115 HBRN give me 171pf. I would probably start at 10 grains and work up. The MPA barrels I have shot are much faster than my Bul.

Looks like 9x25 Dillon?
