nelly Posted April 20, 2015 Share Posted April 20, 2015 Hi All, Anyone have a recipe for Montana Gold 121 IFP using HS6 ? They'll be used in an STI 9mm Major "Tru-Bor", my standard load for HS6 has been 124gr MG JHP with 8.0grs-8.3grs of HS6 seated at OAL 1.155-1.160 & Sm Pist Primers.....Thanks Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted April 20, 2015 Share Posted April 20, 2015 Probably an extra grain should do it - building slowly with a chrono, of course. Link to comment Share on other sites More sharing options...
Sarge Posted April 21, 2015 Share Posted April 21, 2015 Probably an extra grain should do it - building slowly with a chrono, of course. A GRAIN?!? I would bump it .4 and chrono. Link to comment Share on other sites More sharing options...
Tyshoots Posted April 21, 2015 Share Posted April 21, 2015 Do not go with full grain on the 121. I went to 115's and .8 grains got me to 170. Link to comment Share on other sites More sharing options...
pbairborne Posted April 21, 2015 Share Posted April 21, 2015 My load which gives a PF of 172 is 121 IFP/8,7 HS-6 at 1.175 OAL. You appear to be loading shorter, so it would make sense to start lower and work up with a chrono. Link to comment Share on other sites More sharing options...
jcc7x7 Posted April 22, 2015 Share Posted April 22, 2015 Go up about 4% or 0.3 I'd start with your same load as the 124's and work it up like others have said Link to comment Share on other sites More sharing options...
Cowboy1629 Posted April 22, 2015 Share Posted April 22, 2015 I use 8.7gr of HS-6, CCI SRP, 1.165 OAL. Gives me 173 PF out of my 5" Cheely. Link to comment Share on other sites More sharing options...
AWLAZS Posted April 22, 2015 Share Posted April 22, 2015 I used 8.7 of hs6, Tula srp at 1.165 oal. My powerfactor would run around 173-175 out of my Cheely gun. Link to comment Share on other sites More sharing options...
Gary Stevens Posted April 29, 2015 Share Posted April 29, 2015 Wow I only use 6.6 of HS 6 at 1.10 to make 174 with the 121 bullet. I use the spacers in the mag and all is well. Link to comment Share on other sites More sharing options...

Every Open recipe I have ever seen for HS6 was north of 8 grains Link to comment Share on other sites More sharing options...
Gary Stevens Posted April 30, 2015 Share Posted April 30, 2015 (edited) Obviously I load by chronograph but that is what the scale shows. I'll put the check weight on the scale and verify it. Scale is correct. Weighed again this time 6.6 gr. Edited April 30, 2015 by Gary Stevens Link to comment Share on other sites More sharing options...

Weighed again this time 6.6 gr. I guess you are lucky. One of the downfalls of 6 is that it fills the case so much you have to take a little more time loading it.
