New member! New to 10mm! First post!

Univibe · May 09 2018 04:22:31 PM MDT

Hello, everybody.

I shoot / reload .45 for the range. I carry 9mm. But I've always wanted a 10. I don't know why that is. I really don't like hard-kicking guns but for some reason I always wanted a 10mm 1911.

Well I did some trading and got me a new Springfield Operator 1911. In the hand it feels like Darth Vader's 1911. Makes my Govt. Model .45s feel positively tame.

I haven't shot it yet, but I now have dies, bullets (Hornady 180 grain jacketed flat point), 500 new cases (Starline). I have a case gauge on the way.

I'll be starting with Accurate Arms #5 powder, which I already have for 9mm and .45. Although the weight of authority seems to be that #9 is better.

I got a box of factory ammo (SIG, 180 grains at 1250 fps) for testing, and I loaded up 25 rounds of home-brew.

Now all I need is a free afternoon for range time.

Welcome aboard!

Enjoy your new Springfield 10mm. I have to Glocks in our favorite caliber. A 1911 will be my next purchase in ten.

Univibe, Welcome to the forum and the world of 10mm. #5 is a little on the fast side for the 10mm but it does have several applications, especially as target plinkers. Accurate #7 and #9 do a better job with respect to pressure vs. performance with most bullet weights.

If you like the Sig performance, Alliant BE-86 was what we saw inside of them.

Be sure to post your results and experiences.
Best regards! ${$default_cheesy_smiley}$

Here's what I think I want to do:

There are 3 levels of 10mm that I can see. There are loads that duplicate .40--why bother? There are very hot loads that duplicate the old Norma stuff (700+ foot pounds). And then there are mid-range loads that are more or less what my box of factory Sig loads will do, 180 grains at 1250 fps. These are the ones I want to load to. According to AA data, #5 won't do this but #9 will. The 25 loads I made with #5 look like they'll be hotter than .40 but not by very much.

Much as I hate to, .looks like I'm going to have to inventory another powder.

Welcome... the two I lean for in 10mm now are first Blue Dot, and then #9.
Tho I have tried 2400, Autocomp, and Unique ( 800 is really good but a pain to auto drop and must be weighed )

Blue Dot, Longshot BE-86 and #9 are my go to powders right now. All will match the SIG ammo at safe pressures.

This is my go list as well. But I also use #7 for plinking.

Thanks for the suggestions. Sounds like a can of AA #9 is necessary.

Bat Rastard · May 10 2018 05:07:45 PM MDT

I am very pleased with BE-86. It is great for 9 also. I haven't loaded 45 with it yet, but it looks good on paper.

Picked up a pound of Accurate Arms #9. Having already loaded some light ones with AA #5, I think I'll load about 25 hotter ones with #9. Maybe duplicate the SIG factory ones I have: 180 grains at about 1,250.

Itching to fire the new gun. Won't have time this week or this weekend, but maybe next week.
