Got a ported barrel for my DS9 need a load start point

[Bwilmot]

Well I sent my gun to MPA and had them put a Ported Barrel in it. Now I need a starting load to make the ports work.  With my normal barrel, I run a 135 gr. bullet and a fast powder  .  I would like to try slower powder with a lighter bullet since IDPA  doesn’t have a bullet weight floor. Has anybody tried this before?

115s with 6.2 of hs6 in my ported 1911 had me at 1150 fps and it shot flat, very accurate and very little felt recoil.

Side note.  I had 6 1/8th inch popple holes in my 1911.

Nice I have a few pounds of that tooo.   I usually shoot open with aa7 so I know the major loads.  Just new to the ported stuff.   Thank you for your assistance

I've shot USPSA for 13-14 years. Started with IDPA but gradually preferred USPSA. Lately I've shot a couple of IDPA matches. Fun for a little changeup. Looking at the gun pictured it seems funny that today that's an IDPA gun.

I know right lol.   I started with IDPA 9 years ago and also found that uspsa was a way better sport. Now that they have changed the rules it’s kinda fun again.  Also now that we have LO in Uspsa I can shoot something besides open if I feel like it.  Iron sights are just getting hard to see anymore.   Hopefully my dot stays close between the 2 barrels

I ordered the MPA DS9 IDPA pistol 4 weeks ago with both a standard and a ported barrel barrel. I'd be interested in knowing what load data you come up with if you don't mind sharing.

I don’t mind sharing a bit.  Going to start with the work up this weekend.  The gun was awesome with 135 blues over 3.4 of titegroup @1.145.  129pf.  
If they wouldn’t have changed the rules I would be perfectly happy shooting that load.  But since they allow ports and I’m a mid level master shooter. I’m going to see if I can get a little more of an edge on the shooter thst are not running a ported barrel.

Looking forward to hearing how the DS9 shoots with the ported barrel.

I have also been loading with Titegroup at about 130PF so I'll be curious to see what kind of loads work well with the ported barrel.

Update 

 

I tried the 6.2 of HS6 under a 115 grain plated bullet and it didn't make power factor 124ish PF . It shot nice but nothing special . Then I bumped the load up to 6.7 and it made 130ish PF . Still it didn't seem like anything special . I also tried the normal load of 3.4TG under a 135gr bullet  thinking it would loose FPS. Well surprisingly  it didn't  was still the same 130ish PF. 

 

Then I tried 5.6 of AutoComp under a 115 133PF  and this is the way .The gun settled down and acted like a ported gun should act like. I will load several hundred  and shoot The Battle of The Berms this weekend  should be a great level 2 match. Ill chime back in and let ya know how it worked out next week

Thanks for the update. Look forward to hearing how the pistol acts after a match worth of shooting.

Update on the ported barrel.  
 

I have found that my normal loads work better than any lighter bullet combo.  My load is a 135blue over 3.5 titegroup @1.145.  Gun is supper soft and flat.
