jcc7x7 Posted August 31, 2013 Share Posted August 31, 2013 Any body worked up a nice 10mm major load at about 170-172 PF for the 10mm. I've got lots of full power loads but want to use this gun more than for hunting and full power fun shooting. Would like to use in SS this winter, Shooting 180 lead or jacketed bullets, i've got both Thanks for any input jcc7x7 Link to comment Share on other sites More sharing options...
kneelingatlas Posted August 31, 2013 Share Posted August 31, 2013 (edited) It should just need a little more powder than a .40 load with the same bullet and powder. I'm thinking 4 grains of Clays under a 180 grain lead bullet should get you close. Edited August 31, 2013 by kneelingatlas Link to comment Share on other sites More sharing options...
jcc7x7 Posted August 31, 2013 Author Share Posted August 31, 2013 I've thought about the 40 plus a little option but wanting to see if anybody has done more than I have so far. Thanks for the input. I've got a 180 Pf load on the first attempt with 5.3grs of titegroup and 180 hornady HAP. still looking for some more options Link to comment Share on other sites More sharing options...
jmbaccolyte Posted August 31, 2013 Share Posted August 31, 2013 Start with about 4.9 grains of WST with a 180 grain bullet at 1.23" OAL or longer and work from there if needed. Link to comment Share on other sites More sharing options...

blaster113 Posted September 3, 2013 Share Posted September 3, 2013 When I was working up full power loads (right up to max) with Silhouette and HS6 my SD and ES began to get smaller the closer I got to max. I think the 10mm likes to be loaded HOT. With about 8.2 grains of Silhouette I worked up a decent feeling load which ran around 1080 fps/194 pf out of my Gen 4 G20. My starting loads had ES of 80+ fps and huge SD. Havent tried my usual .40 powders, N320 and Solo with the 10mm yet. Link to comment Share on other sites More sharing options...
tsp45acp Posted January 30, 2014 Share Posted January 30, 2014 Don't know what PF this has, but my load is a Penn 180g fpl w/8.8 LongShot 1.250oal. Nice load. Tracy Link to comment Share on other sites More sharing options...
G29SF Posted February 10, 2014 Share Posted February 10, 2014 180gr at 170 pf is what, 950 fps? I didn't realize you could make a 10mm go that slow? When I think 10mm, I think 250 pf range... Link to comment Share on other sites More sharing options...
Justsomeguy Posted February 15, 2014 Share Posted February 15, 2014 (edited) Yes, I would think that you would want the heaviest bullet possible with a medium-fast powder to viably get to about 170PF with a 10mm and still give decent ES and SD figures so you know you will chrono well at a match. The uber-fast powders would be low on my list though as that big case might not like them with a heavy bullet. No matter what else, you still have to "run the gun" so you're probably looking at a spring change anyway from the "normal" recoil spring but still heavy enough to feed nicely and return the gun to "zero" for follow up shots.

jmbaccolyte Posted February 16, 2014 Share Posted February 16, 2014 jcc7x7- It makes sense to strive for low ES and SD numbers, but I worry more about the size of the groups on paper. Maybe its just me, but they don't always seem to go together. I've used Clays ("an uber-fast powder"- in my opinion) with this combination and it was really sweet shooting (and clean) with 180 grain bullets, but that particular lot of Federal primers were starting to flatten at 170pf and I didn't feel comfortable. I know that better and smarter shooters use Clays with this combo without any problems, but I decided not to and switched to WST. You can run Clays for minor pf, WST for major pf and Longshot for maximum pf, with just recoil spring changes as noted above. Wolff gunsprings sells an assortment. If you shoot many maximum loads, then the Sprinco recoil reducer is the way to go (Nealio clued me in on this one). I like the Thompson Contender with a scope in .44 Rem mag for hunting. Good luck and have fun. Link to comment Share on other sites More sharing options...
jcc7x7 Posted February 18, 2014 Author Share Posted February 18, 2014 Guys thanks for the input. For the record, been doing this (reloading) for 40 years but always ran thing at the top end of stuff ie 10mm at 1200fps etc. the BUT was I wanted to use the gun more than for just hunting and heavy target use. I came up with some loads with Sr4756, WSF and old school unique. THEN did the easy thing bought a 40 S&W nowlin barrel and fitted it and now have another two barrel gun So the problem has solved itself. After a couple of local uspsa matches my "brass munger" really rose up and I couldn't bare to loose any 10mm brass so I had to get the 40 bbl. LOL Thanks again for the input guys jcc7x7 Link to comment Share on other sites More sharing options...
Justsomeguy Posted February 20, 2014 Share Posted February 20, 2014 For several reasons the barrel change was probably the best solution. You don't have to lose too many 10mm brass to see the economy of changing to a 40S&W barrel and the .40 brass is readily available from a lot of sources. Shooting the .40 in the heavier gun will be a lot more pleasant than even mid-range 10mm and load information for 170pf loads with the .40 is common with many powders.
