Anyone have some loads for 10mm using longshot? Been looking cant find it.
have you tried looking in the 10mm reloading forum under the sticky hodgdon data thread?
just browsing through I found loads ranging from 7.2gr of longshot up to 9.2 gr
I've loaded a 165gr Golden Saber over 9.0gr Longshot and got 1390fps average (708 ft/lbs) with an ES of 87.75 and SD of 33.22. This was from a 6" Fusion.
YMMV so do your own safe workup, please.
9.4 gr longshot= 1320 average fps out of my Kimber with 5" barrel
8.9 gr = 1265 fps
Sounds like 9.4 is getting sloppy. In my testing with 155gr as long as i was below 10gr it shot decent. When I went above 10gr is was like a shotgun pattern. I concluded that longshot is a poor powder for hot light rounds if your looking for accuracy. The 165gr May shoot better but with what is reported with 9.4G with an es that high it does not sound like good. Love longshot for my 180s.
I don't know if the higher ES was due to metering issues with my new charge bar or with the load in particular, just FYI. I've found LS to be great in almost all bullet weights for 10mm, both accurate and heavy bullets.
I've gone up to 10.2 which keeps me over 1400. It's very accurate to 25 yards. But that's only as far as I shot it on paper.
Legal disclaimer...This works in MY gun. It'll probably blow yours up. Use at YOUR risk. As always, start really really low and work your way up.
I went up to 11grs over a WLP primer in my stock barrel...
nothing crazy happened, but I wouldn't recommend it.
I'd say 10grs is my max in a stock barrel.
I went to 11.5grs, no problems, even with the stock barrel. Once again I wouldnt recomend more than 10grs in your gun because it will blow up and put your eye out .
I'm not gonna go much, if any farther, I do want to see how well longshot+165's powers my new comp
