Thank You All!

I am thing about using my Dillon 600 Swage to open up the S&B  primer pockets.

Thank You!!

I couldn't find any Blue Dot or AA9 locally, but my LGS did have some Longshot. I picked up 2lbs.

I am starting to deprime my 10mm range brass for tumbling then I will be loading the brass on my 750 with the Longshot and 180 gr FMJ bullets.  I will be using Mighty Armory dies.

I will be shooting these loads from an 8" barrel.

Any recommendations? This will be my first 10mm loads.

Are you sending these cylinders out to be reamed to 10mm Mag.?

Bump to the Top

I got my Holosun H510C-GR, (Green Dot), yesterday. It is mounted on my CMMG 300 MK10 and ready to site in.

Kent,

What length is your barrel?

I may use Blue Dot for my 8" barrel. Do you think I should look at a different powder?

This Post is Great Timing for me. I just picked up a CMMG MK10 300. I also pickked up 20 additional 30 round magazines and 1,400 once fired cases. I am now putting together a die set and I started with the Mighty Armory 40/10 Sizing Die.

I am looking for 40 S&W and 10mm Pet reload recipes. I do have a S&W Shoryforty that I want to reload for.Thank You for sharing your experiences with us. Win 231 is a powder that I do have and use.

Here is my MK10

Just to point out, I need TWO crimping dies using the Hornady progressive.  I really like the Hornady crimp die as it has the little sleeve that falls down to help center the bullet as it starts into the case.  I use it to seat for depth only.

Now the question again.  I have two options for the second die.  The Lee FCD no guts needed puts the case mouth at .422 loading jacketed bullets.  Or I could use the Lee .44mag FCD and put the 10mm taper crimp guts into it and adjust it to just remove the case mouth probably still at .422. 

I could probably buy another Hornady crimp die as well if it was actually necessary.  Since I am now loading only jacketed 180/200gr bullets would there be an accuracy difference in using the two FCD's above to finish off the case mouth?

I purchased a Mighty Armory 40/10 sizing die. Wayne, owner of MA, told me his sizing die will remove the entire bulge on 40/10 brass. I also purchased a MA .40 expanding die. I still need a crimping die and I plan to purchase a Redding Micro Seating Die in the near future.

Thanks.

I do reload for suppressed 6.5 CM, 9mm in MP5s, 7.62x51 in a Smith M21, 556 for a Colt M16& AR15, and 45 acp for a 100 % UMP clone. My Gemtech UMP 45 suppressor is dedicated for the UMP only. HK used a strange mounting system on their HK UMP Barrels.

I just wanted to know what powders you all may prefer reloading for suppressed 40 S&W and 10mm.

I am planning to purchase a 45 acp suppressor and I want to mount it on my MK10 CMMG Pistol.

I would like to get your thoughts and experiences with powders and bullets that you all prefer to load and run in your suppressed 10mms.

Thanks Everyone for your input!
