Stephen7942 Posted January 28, 2020 Share Posted January 28, 2020 Looking to get into PCC. Going to pick up a JP GMR-15 soon. I believe I’m going with the 14.5” pinned and welded muzzle brake . I currently load 147g Xtreme plated bullets for my CZ shadow. I have some 124 Precision Delta hollow points I could load as well. Currently using 3.2g tite group for my pistol loads. Any advice on load data and OAL difference for shooting those through a longer barrel? thanks in advance for any input or advice. Currently loading on a D650. Take Care, -SS Link to comment Share on other sites More sharing options...
looking4reloadingdeals Posted January 28, 2020 Share Posted January 28, 2020 I found I could use 0.1-0.2gr less titegroup under 147s and get good results. With Brazos coated bullets I found 3.0 to be a little hot and I was getting flattened primers, so I backed it down to 2.8 and have nice rounded primers and ~145PF. These are seated at 1.100-1.110”. With Everglades plated bullets I like 3.0gr at 1.135” where I use 3.1gr for my pistols (3.0 works well, but I get the occasional failure to lock open on an empty mag so I bumped it up). All loads with Titegroup powder out of my foxtrot mike 16” barrel. I only have ~2-300 rounds of reloads through the gun at this point, so there could be a better load out there that I don’t know about yet. Here is a link to a google sheet I started with my load data and chrono data: 9mm Load Data With Titegroup Powder https://r.tapatalk.com/shareLink/topic?share_fid=16618&share_tid=281435&url=https%3A%2F%2Fforums%2Ebrianenos%2Ecom%2Findex%2Ephp%3F%2Ftopic%2F281435-9mm-Load-Data-With-Titegroup-Powder&share_type=t&link_source=app(Shared from my phone let me know if the link doesn’t work) Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
grsdoug Posted January 28, 2020 Share Posted January 28, 2020 I run Precision Delta 124 JHPs with 4.0 grains of Titegroup @ 1.10 OAL. Super accuracy out my GMR, Scorpion, and MPX. Getting around 1200fps and one hole groups at 50 yds. Link to comment Share on other sites More sharing options...
lonestardiver Posted January 28, 2020 Share Posted January 28, 2020 OAL should not be a factor for a longer barrel. It is a factor for fit in a magazine as well as chamber dimensions. If everything is within SAAMI spec then it should not change because you are shooting through a longer barrel. Link to comment Share on other sites More sharing options...

Stephen7942 Posted January 28, 2020 Author Share Posted January 28, 2020 Thanks for all the info. I’m gonna build up some loads and test some I already have loaded and see what happens. Link to comment Share on other sites More sharing options...
