Kingman Posted June 19, 2007 Share Posted June 19, 2007 Ok, so had some AA #5 from back in the days of 9*21. Decided to give it a try and see what I could come up with. Chrono'd in both guns gun 1 5.2" bbl 3 port comp with side ports also. NO bbl holes gun "2 4.25" bbl same 3 port comp with side ports, also 2 1/8" bbl holes. Mixed brass once fired, 115 gr montana gold fmj bullets. Loaded 1.16. Federal Small rifle primers First load 8.0 grains Gun 1 avg 1340 fps = 154.1 pf Gun 2 avg 1249 fps = 143.6 pf Not enough by any means but oh my was this soft shooting. It did operate both guns. Second load 8.2 grains Gun 1 avg 1410 fps = 162.1 pf Gun 2 avg 1320 fps = 151.8 pf Still not there, but still soft. Nice dot tracking Third Load 8.5 grains Gun 1 avg 1468 fps = 168.8 pf Gun 2 avg 1383 fps = 159.0 pf Made major in the longer gun easily with no ports, still very soft shooting. Case still has a large amount of space left to load up. Pressure signs don't look bad. I am going to keep working on this a bit. I would like to get it 168 with the shorter gun. Other load if you can find it that really works the comp well and makes major clearly 11.1 grains wc 818 Gun 1 1559 fps = 179 pf Gun 2 1475 fps = 169.6 pf This one works the gun. It is loud and has a hell of a felt impact anywhere but directly behind the gun. It is flat shooting though. It almost feels like a minor load even at 179 pf. I am amazed and if I can find more of this powder will keep using it. Link to comment Share on other sites More sharing options...
Kingman Posted August 5, 2007 Author Share Posted August 5, 2007 Update WC 818 is very temperature sensative. I have been having problems on really hot days with extraction. Turns out cases are sticking with over pressure. Link to comment Share on other sites More sharing options...

This was really nice shooting Short gun - average 1405 a bit of a way off yet 9.0 AA #5 Long gun - 1485 average with a 171 pf. This was SOFT and flat. I am going to play more here Short gun - average 1444 Pressures looked ok. Some True Blue data 115's 8.6 grains true blue average Long gun-1487 with almost no standard deviation. This gave me a 171pf. I want to try more of these loads out Short gun - 1434 a long way to go Have some other data but pressure signs get scary. If you wana know some dumb stuff I tried. pm me.

lynn jones Posted October 26, 2007 Share Posted October 26, 2007 wouldn't be easier using a 124gr bullet? lynn Link to comment Share on other sites More sharing options...
Kingman Posted October 26, 2007 Author Share Posted October 26, 2007 Probably, but I like the flatness of the 115's. Yes I can see a difference. Link to comment Share on other sites More sharing options...
SLM Posted December 26, 2007 Share Posted December 26, 2007 Ever do any more messing with the AA#5? I was thinking about stuffing some behind MG 121's at some point to see how that goes. Link to comment Share on other sites More sharing options...

oldtrooper Posted December 26, 2007 Share Posted December 26, 2007 Kingman, What was the overall length on the 8.8 AA#5 load with the MG 115 ? Link to comment Share on other sites More sharing options...
Kingman Posted December 26, 2007 Author Share Posted December 26, 2007 1.155 I run spacers. Link to comment Share on other sites More sharing options...
mcattack Posted December 26, 2007 Share Posted December 26, 2007 (edited) 1.155I run spacers. when I shot 9mm I used accurate #7 and worked great with 121 but I never tried 115's and never tried #5. #7 works good in super with 115s Edited December 26, 2007 by mcattack Link to comment Share on other sites More sharing options...

Do you know what your load was? I would have to look at my log when I get home . Getting old and memory does not work like it used to. Seems like it was in the 9.+ range. I am shooting super now with 124's cause thats all I could get last time I bought bullets. With 124's 11.5 A#7 No barrel holes.

Kingman Posted December 26, 2007 Author Share Posted December 26, 2007 #7 will overfill standard 9mm cases to make major last time I tried. #5 is what we had to switch to with the 9*21 to make major with lighter bullets. Link to comment Share on other sites More sharing options...
SLM Posted December 26, 2007 Share Posted December 26, 2007 That's what I was thinking about #7, at least with 115's. I thought it might work with 124/5's or heavier. Link to comment Share on other sites More sharing options...
Kingman Posted December 26, 2007 Author Share Posted December 26, 2007 It worked great with 135's and up. Anything below that I could not get it to make major. Link to comment Share on other sites More sharing options...
oldtrooper Posted December 26, 2007 Share Posted December 26, 2007 Kingman, I have never worked up loads for an open gun except Bianchi loads. I mostly shoot stock and limited. What are spacers? Thanks Link to comment Share on other sites More sharing options...
yoshidaex Posted December 28, 2007 Share Posted December 28, 2007 (edited) oldtrooper, Hes refering to spacers in the magazine. STI mags need spacers to position the round properly (slightly forward) so they feed 100% of the time. 1.155I run spacers.

Kingman Posted December 28, 2007 Author Share Posted December 28, 2007 As Yoshi said. Due to the shape of the indentations in STI mags, in order to get them run the right way with 9mm loads some of us are putting spacers at the back of the magazine. These spacers position the round a little bit forward allowing the case to ride on the indentation. Without the spacer in place the bullet actually rides on the indentation instead of the case. This causes a stacking problem in the magazines. Can cause binding problems, and nose dive problems. Link to comment Share on other sites More sharing options...
