MrWallace Posted August 19, 2015 Share Posted August 19, 2015 I've got a few questions floating around and I'm hoping that you guys can help me get the answers! I'm trying to figure out how much Red Dot to use with my 180gr Bayous in order to make major PF. I'll be shooting them out of an STI with a 5" Bull Barrel with an OAL of 1.135 What I've got at my disposal is: Winchester Small Pistol Primers Mixed brass Red Dot 180gr Bayous I've been searching around for a while and haven't been able to come up with any real definitive answer on how much to use. I've got several books, and feel like I've scoured every nook and cranny of the internet but haven't been able to come up with some solid answers. Also, I'm using a XL650 and was wondering if the Red Dot will have any issues dropping? Any other powder recommendations that might be better suited for what I'm trying to accomplish? Thanks in Advance! Link to comment Share on other sites More sharing options...
wgj3 Posted August 19, 2015 Share Posted August 19, 2015 Lots of other options out there, but RD should work. I use it and Promo in 9, .40, and .45. Start around 4.3-4.5 and chrono. Work up as needed watching for pressure signs. Link to comment Share on other sites More sharing options...
MrWallace Posted August 19, 2015 Author Share Posted August 19, 2015 Correction, my OAL is 1.165 Link to comment Share on other sites More sharing options...
TDA Posted August 20, 2015 Share Posted August 20, 2015 (edited) I'm using 4.6 Red Dot @1.140" with Acme coated 180's and getting mid 170's PF from a P226 Sig. Hercules (Aliant) published data shows a max of 5.0 @ 1.125" for 180JHP. Edit: My load data for 4.6 is from memory, as I don't have my notes with me, but I'll verify it in the morning just to be sure.

TDA Posted August 20, 2015 Share Posted August 20, 2015 Just checked and 4.6 of Red Dot was 169PF. Link to comment Share on other sites More sharing options...
ItZallGooD Posted August 21, 2015 Share Posted August 21, 2015 You should be able to download the 2002 or 2003 Alliant reloading manual. It has data for Red Dot in the 40. Link to comment Share on other sites More sharing options...
