Larry Burchfield Posted February 6, 2008 Share Posted February 6, 2008 Anyone out there using this combo in the 38super? Or something close. Larry Link to comment Share on other sites More sharing options...
rvb Posted February 6, 2008 Share Posted February 6, 2008 125gr jhp here... with 8.7 gr 4756. 173-174pf from a 5" trubor barrel w/ no barrel ports. Not what you were looking for, but it's "or something close." Link to comment Share on other sites More sharing options...
ipscbob Posted February 6, 2008 Share Posted February 6, 2008 Yup. I ran that combo for about six months when I was just getting into open. Not my favorite powder and I have since switched to 124gr JHPs. That combo was a bit too snappy for me. 5" gun, 7 port cone comp, and no barrel ports.

trodrig Posted February 6, 2008 Share Posted February 6, 2008 It took 9.1grains of 4756 with 115 MG's to make major in my Trubore. I only shot a few with this combo but it seemed real clean. Accuracy was pretty good too. Trodrig Link to comment Share on other sites More sharing options...
HSMITH Posted February 6, 2008 Share Posted February 6, 2008 BIG lot to lot variations. If you are going to use it chrono each can or buy a case at a time. Works good. Link to comment Share on other sites More sharing options...
pmd Posted February 6, 2008 Share Posted February 6, 2008 9.3g of SR4756 gets me about a 170pf with both Montana Golds and Zeros. Pistol is a Bedell shorty with a Bedell comp and AET 38super barrel I don't recall the OAL. From a Ransom Rest the MG's groups were a bit tigher.

I'll try 9.3 tomorrow, weather permitting Link to comment Share on other sites More sharing options...
boz1911 Posted February 10, 2008 Share Posted February 10, 2008 I'm using 121 grain MG in front of 8.5 grains of 4756 from a 5 inch Bedell. So far I am very impressed, gun seems relatively clean and there are no fireballs. I also got to see a video of a fast 21 round stage and the gun doesn't seem to move. Being new to Open I don't have anything to compare to but at this point the combo seems great. Link to comment Share on other sites More sharing options...

I'll try 9.3 tomorrow, weather permitting Mike, Too early for me to tell - still playing around with loads and bullet weights. I am also looking at other powder options that are not as sensitive as the 4756. Hopefully I'll find a load I like before the season starts.

Great shooting powder for super, much less lot to lot variance than the IMR powders so you dont run the risk of getting stuck with a batch that you cant make major PF with.

I tried 9.3 grain out of my bedell shorty and was running: 35degree in the snow 1405 1399 1400 1428 1393 1396 About 161PF This is a new lot of 4756. so it might be slow. but I am running out of room in the case with 9.3gr The load shot well, but I haven't had a chance to run it back to back with 124. Next week after the match, I will try to Chrono indoors to see what 9.3 does, also try it against 8.6 with a 124 which made 168PF with the last lot I have 7625 on order and may try HS6 and Silhouette. I like 4756, runs clean and shoots well but its a pain in the ass to keep having to Chrono based on lot and weather Edited February 10, 2008 by Supermoto Link to comment Share on other sites More sharing options...
