I am going to give it a good cleaning and try again tomorrow

I just had the XD apart for cleaning. Looks totally different!

Took a couple of pictures. I think this is the piece (don't let 4949shooter see me posting Tupperware pictures ${$default_grin_smiley}$ )

The SD is definitely a departure from the Glock design.

Intercooler, if you are going to post pics of Tupperware on a 10mm forum, make it Austrian Tupperware! ${$default_wink_smiley}$

Not anymore. Good Ole US of A!

I will do a range report of the XDs in .45 when I get it.

I put MT10mm's 220's through the tests today. Through the Hunter I shot two and three from the Limited. All the brass looks really good, no popped primers and good repeatable results. I will get a couple of photos here in a bit and measurements.

EAA Limited 4.75" 1233, 1243, 1243. Average = 1239.66 FPS/ 751 LBS. Last time out I used the Pro and averaged 1239 FPS. Nice!!! ${$default_cool_smiley}$ I'm okay with this load, but other setups might not be and hopefully the new loading drops this a bit.

EAA Hunter 6" 1290, 1275. Average = 1282.5 FPS/ 804 LBS. I never recorded the Hunter data before, but this gives us 6" now.

My guess is the LW barrel then. I shot some 200 UW TMJ yesterday with no real pressure issues with the factory barrel.

I am going to keep my G20 stock and just pick my woods load.

Looking at the numbers, I'd say those were loaded with LongShot...but we would have to see to be sure. $:-\$

These are the new Long Shot loads and repeatable.

Here is the Hunter brass. Nothing to speak of and both measured .433".

Here is the Limited brass with ever so slight flare at the feed ramp. All three measured .435".

Wish I never bought that LW barrel. Should have saved my money and bought more ammo.

They were slammin' the ejectors pretty hard, and little bit of firing pin wipe as it comes out of lockup from both guns. Even from your chambers they are expanded in the area not in the chamber...Pressure expansion ring is showing. I think it would be wise to drop the charge weight by 0.2 / 2 tenths and be satisfied with the velocity and less wear and tear on the guns.

The Glock chambers are around 0.4340" so they will expand a lot quicker and at that level they are over expanding as evident of the "smiles". Not sure what LWD is cutting their chambers to these days. ${$default_huh_smiley}$

With these 220 heavy weights, the charge weight should be adjusted in my opinion! 1180-1200 fps would be plenty enough. ${$default_cool_smiley}$

I planned on phoning Kevin up to see if a change was made. Maybe I can buy just enough to run a decent test on.

mt10mm · January 12 2014 07:01:10 PM MST

IC

If you find out Kevin cut it back I will order some and send you a few to test

Keep me posted

Intercooler · January 13 2014 08:50:54 AM MST

I spoke with Kevin today and they have been changed. If you buy the current lot on the site you are good.
