10mm reloading

rosewood: did you do the P16 conversion yourself?:confused:

Cheers!

Yes. I ordered a barrel from Olympic Arms I think, it was pretty much a drop in. Only took some minor fitting.

However, I did find out that years later Para actually sold them in 10mm, although I never have seen one myself. I guess I converted mine during the 40 S&W years where 10mm had lost favor, but it has flipped now. I was a 10mm fan when it wasn't cool.

Ok, so I received my 10mm bullets, cartridge gauge, and taper crimp die today. I already had 40S&W dies. And after getting mower fixed and grass cut I got to get my reloader set up for 10mm.

Yeeee Haaaaa new caliber. First time in awhile. I started out with 155 gr Hornady XTP's in front of a milder charge of CFE Pistol. It's supposed to rain most of day tomorrow here. More time to get more test loads ready. :)

But hopefully Sunday I'll get some trigger time and I'm gonna set up the chronograph and see what's cooking.
 
We have been loading 10mms since the 1980s. For years used Blue Dot and it worked well. I kept the loads in the middle range because it seems Blue Dot peaks in pressure quickly as you get near maximum. Now we use Power Pistol exclusively. It gives great performance, better accuracy than anything else we ever tried, and no pressure issues.

Oh I've used plenty of lead reloading for revolvers. But I've only dipped a very small toe into lead for semi-autos. I've always assumed, incorrectly I guess? that there would be feeding issues with lead in semi-autos.

Perhaps I should try some more out?

95% of all my 10mm reloads are with 170 gr cast truncated cone bullets. They run like a waterfall through my 1006 and 1911 in 10mm.

I only have a few drops and a sneeze of Power Pistol left. Hoping to get my hands on some soon.

That's a nice shooter there. I'm sure recoil seems pretty mild on that SRH. I've had a 10mm itch for awhile. The cheapest way to get it scratched would be a Glock. I would doubt you could get a Glock to shoot like that at 25 yards though.
 
Been loading 10mm since the 80's when my PD adopted the S&W M1076 for our first auto duty pistol. Issue ammo was the '10 LITE', Federal or Remington 180 gr. JHP at ~950 fps. (this was 'pre-.40' days...)
Later, I added a Colt DE SS M1911 and have always enjoyed that more.

Anyway, to semi-duplicate the 10 LITE, loaded 175 gr. LSWC's over 5.5 gr. of WW231.
Hunting loads, i.e, 'real 10mm' have been Hornady 180 gr XTP over a max charge of AA-9. Shoots great.
 
I looked for a 610 and a 1006 for a long time. Both are great guns but it seems collectors are buying them up making them hard to find and expensive if you do find something. Anyway I see a P220 Sig and a Ruger SRH both in 10mm during my travels and bought them both. Both are tanks, especially the SRH, and both shoot great. I would still buy a 610 or 1006 but now only with the right deal.

The Sig feeds lead SWC without issue. I had a 1911 in 10mm for years and it too fed SWCs with no problems.

I load & test more 165gr bullets than I do 180gr but the best powders are pretty much the same for either.

I like Power Pistol, Long Shot, Blue Dot & AA#7.

Anything faster than Power Pistol or slower than AA#7 is out of the sweet zone for the 10AUTO.

Power Pistol & Blue Dot have lots of muzzle flash but not Long Shot or AA#7.

AA#7 is quit a bit slower than Blue Dot in the 10AUTO:
B-D @ 12.0gr = 1382mv
AA#7 @ 12.0gr = 1292mv

Here are my max loads as tested in my 1006.

(The best load, AA#7, gains ~110mv & ~120me in my 8" CMMG Banshee compared to the 5" M1006.)

CAUTION: Some of these loads are above published maximums. Work up slowly. Use at your own risk.

Ok, so I got a bit of trigger time in with the 10mm and the chronograph today:

S.A. XDM 10mm 4.5 in barrel 5 shot groups

1. 155 gr. Hornady XTP 8.4 grs. CFE pistol CCI LPP
Avg. velocity 1304, low-1293 high-1321

Liked this load, shot way high though on target.

2. 155 Hor. XTP 8.8 grs. CFE Pistol
Avg. velocity 1342 low-1308 high-1364

Didn't seem like much gain for more recoil and muzzle blast.

3. 155 Hor. XTP 6.5 grs. W231 CCI LPP
Avg. velocity 1162 low-1151 high-1169

Seemed very mild compared to CFE pistol. Grouped well but again everything is high.

4. 155 gr. Hor. XTP 6.9 grs. W231
Avg. velocity 1210 low-1197 high 1232

I believe CFE pistol might be the one for me with 155 gr hollow points. I think 1300 FPS will do me. Not sure I want to try and wring out 100 FPS with Blue Dot or something?
 
NOW 180 gr FMJ tests:

1. 180 gr. Hornady FMJ 7.0 grs. CFE pistol CCI LPP
Avg. velocity 1098 FPS low-1089 high-1110

2. 180 gr. Hor FMJ 7.3 grs CFE pistol CCI primers
Avg. velocity 1117 low-1104 high-1137

I think this was the best group of the day, will have to take another look.

Armscor 180 gr. FMJ factory load

Avg. velocity 1033 low-1022 high-1043.

I'm just in the very beginning of trying out load combo's and still very much learning trigger/gun/recoil and so on.
 
I use CFE with jacketed 180 grainers, but I like W231 with Xtreme 180 gr. plated boolits in both 10 millie and .40 short and wicked. Both shoot very clean with adequate power and good accuracy.
