Best Powder for 10MM Hunting Cartridge

[FrankPar]

I believe Blue Dot may be the best powder for a 180 grain bullet in 10mm. Clean burning and excelent velocity. Does it create too much flash for you Jingles?

[TurboFC3S]

I load 10mm with either Blue Dot or 800x for hunting loads in my Fusion Longslide. You can get a bit more velocity at the same pressure with 800x, but it's hard to use my Dillon to meter it ... and when you're pushing the limit you need accurate powder throws. So basically, if you want easy metering with a progressive use Blue Dot ... if you have something like a ChargeMaster or don't mind hand measuring use 800x.

I know this is an old thread but my choice would be AA#7. It just works well in anything you load for the 10MM. I have been using it for years and have never needed to change due to its excellent metering and consistent groups/MV. Just my 2 cents.

Thanks to you guys for the suggestions. I have decided to use blue dot since I have heard nothing but good stuff in heavy 10MM loads. I am going to use a 200 gr,XTP. I have read that 10.5 grs. of BD is a very stiff load but have not seen much written data on this mixture any where. Any input from you guys would be very helpfull. I am going to shoot it out of my 6" Fusion hunter. I need every oz of energy I can get because I am hopefully going to send it flying at a bull elk this September, Thanks Mirando

Start at 10gr, or even 9.5 and work up ... do you have a chrono?

10mm is good for reading primers as a judge of pressures. Work your way up and read those primers, and hopefully verify with a chrono since you're wanting to go nuclear.

[Mirando Ketner]

Yes I do have a chrono and I will also watch those primers. Thanks, Mirando

You're set then, time to go NUCLEAR!

Bull elk with a 10mm? I wouldn't. I had to empty a 30-30 lever gun at an angry wild boar once, I will never again go hunting with a marginal cartridge for the job.

Back to the topic: Accurate #9 with 200gr bullets, Accurate #7 with 180gr bullets have always been powerful and accurate in my G20 and Delta. Either will do a great job on bowling pins.

I dont dont consider 10MM marginal. I have already taken several hogs with it. But we shall see. Taking a 300 win mag just in case, Mirando

How did your hunt go?

Some Longshot numbers from Double Tap founder Mike McNett;

Here is some info from my work with Longshot. Always start 1.0gr lower and work up in .2gr increments until you see pressure signs. (Waters' method):
Starline Brass, CCI 350 primers, 1.26" OAL. 10 shot avg. G20 85F and 5000ft elevation.

135gr Nosler 13.2gr LS - 1542fps
165 GSHP 10.4gr LS - 1356fps
180 GSHP 9.6gr LS - 1294fps
200 XTP 8.2gr LS - 1172fps

These are loads that I have worked up to and are under 37,500psi when I had them tested. I hope this helps!
-Mike

Longshot for 155 gr Rainier RN (copper plated) with 12.4 gr of Longshot, OAL 1.260, 1450 FPS.

++++++++++++++++++++++++++++

I loaded up 165gr Golden Sabers around Thanksgiving time, CCI 350 primers add about 30fps and reduce ES compared to WLPs;

G20 SF, 4.6" Lonewolf barrel - fully supported;

4250ft, 55F, 9.9grs Longshot, Win brass unk firings, CCI 350, COAL 1.580"

1398fps/716fps, ES 27fps, SD 08fps

++

180gr Gold Dot, 9.3grs Longshot, COAL 1.60"

1314fps/690fpe, ES 40fps, SD 11fps

Longshot is an excellent powder to work with and packs a punch; apparently at lower operating pressures.
