So if I understand, it doesnt require much more energy? Very interesting..... not intuitive at all. Link to comment Share on other sites More sharing options...

HS6 or slower. HS6 and load as long as your throat will allow maybe? AA7? 3n38? 1.18"+? I'm shooting 115gr 9mm bullets with HS6 in my Open gun, and very happy with it... Lately I've been thinking about trying AA7... I know you're an HS6 fan, have you ever tried AA7? Link to comment Share on other sites More sharing options...

Knguyen1904 Posted April 25, 2018 Share Posted April 25, 2018 I’ve played with all the different 9 bullets and I’d say you’d want to go lighter depending how efficient your comp is. I personally think 115s are the best. my gun seems to track a slight bit faster with the lighter billet and heavier charge. Link to comment Share on other sites More sharing options...
kneelingatlas Posted April 25, 2018 Share Posted April 25, 2018 Everyone has different preferences surrounding their component choices: -loudness -soft impulse -muzzle rise -ease of loading -component pricing -wear on gun components -peer approval ? And every gun is a little different: -barrel length -component design -barrel ports -weight You can absolutely load 9 major using 147s, in fact a friend just reported back how much he loves AA7 under 147s in his Tanfoglio Gold Team. The Gold Team is an extreme example as it has 12 holes in the barrel and a tiny comp, making it very loud and violent with traditional loads.

d_striker Posted April 25, 2018 Share Posted April 25, 2018 I shot 147's when I first got my open gun since I had a ton of them and was waiting on my 115's to come in. I used WAC for the 147's and am still using it for 115's. The 147 load felt less harsh in the hands but had more vertical dot movement than 115's.
