I strongly recommend aftermarket barrels with fully supported chamber for handloaders using AA#2 or AA#5. AA#2 is a fast burning, clean, low flash, powder that you should not push. .2 grains beyound the www.accuratepowder.com 5" barrel data Glocksmiles (ruins) used Winchester brass. Listed maximum loads are actual maximum loads! What kind of fun is that for the curious and innovative reloader? There is a growing body of statistics that shows little room for error with AA's fastest burning powders. Exercise appropriate caution. The 5" data does not look too impressive compared to the competition, however for G-29 3.8" barrels, the data listed is very close to actual performance, because the powder almost completely burns in the the short barrel. (Similar to Alliant Power Pistol performance in a short barrel, except that Power Pistol is fairly forgiving with a 5% to 10% push.)(Bullseye is more accurate, but has to be pushed more than 10% to reach similar power levels.) My load for a 165gr BJHP is 7.8gr @ about 1245 f/s, 568 fLbs, PF 205. My load for a 180gr BJHP is 7.4gr @ about 1176 f/s, 553 fLbs, PF 212. (Note: Hornady XTP is higher friction design and the powder charges must be reduced. Use caution to build up a load specifically for your gun starting at a lower powder charge, no matter what bullet you choose.) I use the 155gr Speer Gold Dot as listed in published data and the 165gr Rem. G. Saber listed in the loads above as my nightstand loads because the numbers are just about ideal for that purpose. The 180gr Rem. G. Saber is a better penetrating load if that will serve your purpose.
