I just purchased an EAA Witness Match Combat Sport 10, and after massaging the action and polishing everything in sight, it feeds great. I just need to find out if anyone on this thread knows any info for the Sierra 135 rg. bullet, as I have a full box from loading my .40S&W. I have heard that I can use a max load of Unique (8.5 gr, in the Sierra manual) for the .40S&W as a starting load for my 10MM with the same bullet. I cannot seem to find any published info for this bullet wt., and I have the latest Sierra, Speer, Hornady and Nosler manuals. I would like to use Unique or Blue Dot, as I already have plenty of these powders. I would really appreciate any help, as I have become quite a fan of the 10MM! My Witness put 5 rounds into a little over 1" @ 25 yds with CCI Blazer 200 gr. NR stuff. I'll be using new Starline brass, as I ordered 500 cases last week and received them in 5 days, for $79.95, including shipping. Starline said they have plenty of 10MM in stock, if anyone else needs some! God bless.

If a powder is not listed it is a good indication that it is a poor choice for a cartridge… You don't think they hide the good ones do you
Blue Dot and AA 9 have been the best performers with this cartridge since it was introduced. (obviously an exception or 2, but few) |

Nosler #6 page 677 also has data for their 135gr bullets. |

Nosler #6 page 677 also has data for their 135gr bullets. Small light bullets usually used in 40s have an inherrent problem when loaded in 10mm. Due to the lack of surface area of the bullet inside the brass, recoil of the 10mm tends to shake them loose. Keep an eye out for that, shoot a few and check remaining rounds to see if length has changed. Good Luck. Please give us an update. I have been looking at the EAAs but few people have them in 10mm, I will be interested to hear more. |
I cannot believe how short-sighted I was when I first looked in my manuals! I guess I was just interested in Unique, and passed by the info I needed for Blue Dot! What little hair I have left is all white; does that qualify me for a "blonde moment"? Thankyou for your info, and as a passing warning to others about getting into too much of a hurry to shoot your new pistol, I must confess that you guys indirectly may have saved my bacon! I had researched loads on the internet for some 150 gr. Sierra HP's I have and found a load at a site, which shall not be mentioned, which gave a charge of 12.8 gr. Blue Dot with that bullet. Well, I thought that sounded great, and loaded up a few with 12.5 gr. and set them aside for testing. Thank God I came here, 'cause what you said made me go back to my manuals and I found that page in the Sierra manual and a Blue Dot load for the 135 gr. bullet that maxes out at 12.0 gr! Needless to say, I am humbled by my lack of proper research and by your kind assistance, and am in the process of pulling those loads today! God bless and keep up the good work.

I like it just fine :) Never had any feeding issues with it. |
