I use 2-Port on 3 of my Open guns. Absolutely LOVE IT. I run SWMP/AA7 with MG JHP 115gr at 172PF .... and its so flat. Here is it

I am almost out of my last 8# keg of SWMP..... cant find anymore. Anyone have any leads on some AA7 maybe?

Big Sticks for me

Perfect. WSR is a go then! Loaded some up with 124gr MG JHP on top of 4.0gr of TG @ 1.125 and we shall see how it does. Ill Test TG and WSR at the same time. My usual load for X5/Max is 124gr MG JHP on top of 4.3gr of VV320 @ 1.125 for 133PF

What is your purpose for new build?

Sounds promising! I can also seat them nice and deep.

This specific to Sig so I will post it here. I am down to 5k of Win Small Pistol Primers..... Have Sh*t ton of Win Small Rifle and CCI Small Rifle...... Question is should I start searching for a trade (damn hard since all the Facebook policing) or WSR and CCI 400 will ignite 100% OK ?

My vote is NONE. I dont use one.

I 100% agree with Sarge. You need to reload to get an optimum performance out of your Open gun. CO with factory ammo would be my vote for your situation. CO division is huge now and very competitive. Fully built P320 or CZ will make you very happy.

sell both limited guns and build an exact carbon copy of your current Open gun (if you like your current Open gun setup)

Winchester Nato is usually little hotter. But Erebus will eat anything really. Are you trying to have faster moving slide? or you trying to get more gas to work that comp? Either way I like normal 130pf minor ammo for Erebus after playing with all kind of custom loads from 125pf to 155pf

Same... 6 mags setup same way. I can fit 23+1 to start

Yeah buddy! They also had 115gr JHP along with 124gr JHP today as well.

127 vs 133-135 will give you zero edge in accuracy. Edge in confidence is all in your head. What you Can Possibly get (and its real) is spending thousands on travel expenses and coming up on Chrono that clocks slightly slower..... and you get to shoot a Major match for Fun and No Score. Loading at least 5+ PF SHOULD give you confidence that you will never fail chrono. Your gun will cycle faster more reliable. Your dot will return faster for your follow up shot. But this is my personal opinion and I shoot Open with occasional CO here and there. LOL

Wilson Combat grip module is much slimmer and more ergonomic

What did you end up doing bro? Did you use the ammo? Reason why I am asking is because at A1 we had pretty large group reporting that Chrono reads 3-5PF low. My Major load that was used in several major matches was always 171..... it chronoed at 166. Too close for comfort.

6am like a clock... sometimes little after. every day. Today they even had 115gr JHP

I had same issue with MG JHPs and Dillon Seating Die. Problem is the seating stem. It needs to be modified. Flipped or not it will touch the top of the bullet when seating and will not align or hold it it properly during seating operation. You have to Drill the center out and then put seating stem in drill, Wrap some sand paper around the ogive on the bullet and make seating stem to conform to the contour of the bullet. I have some pictures.... but I need to find them.

MG 124gr JHP are available pretty much every day for about 30 min or so. Lately been around 6am PST

115gr/124gr JHP @ 1.169 for Open and 124gr JHP @ 1.123 for CO

Its possible that springs will break in a little bit after use

Hmm... I picked up 6 of TTI Pads last week from Shooters Connection. 22 Reloadable, 23+1 to start.

No need for special follower. My 21rd mags just needed TTI Base. Stock Spring and Follower. I can fit 23 rd no problem

I picked up 6x 21rd mags from Dawson Precision last week. Little more $ than usual at $57 but shipping is free and no Tax. They still have few in Stock. https://dawsonprecision.com/magazine-sig-p320-9mm-21-round-coyote-tan/

Any Seating die will only be as accurate as a seating stem fitted to the bullet profile. The better the seating stem hugs the bullet by Ogive/sides and not touching the tip of the bullet. The better your OAL will be.
