sdm74 Posted May 6, 2011 Share Posted May 6, 2011 Does anyone know if kkm or storm lake barrels are faster then stock? I am having trouble making pf with 3.5 tg with a 147gn bullet. My 4.5 xdm made pf at 3.4. With m&p im getting low numbers how can extra half inch be slower. FWIW my friend shot same loads and they passed in his glock with no low numbers Link to comment Share on other sites More sharing options...

bmiller Posted May 7, 2011 Share Posted May 7, 2011 (edited) I use 3.3 g of tg with a 147 gr extreme plated bullet and it made 131 pf. My barrel is kind of rough from the factory. At some point I will buy a kkm. Edited May 7, 2011 by bmiller Link to comment Share on other sites More sharing options...
RWF Posted May 8, 2011 Share Posted May 8, 2011 do not reload, but we tried a friends power puff load he uses in his 34 but in any of our Pro's it made a big jump in the wrong way. from about 128 pf in the 34 to over 135 in the M & P Pro. Link to comment Share on other sites More sharing options...
Sarge Posted May 8, 2011 Share Posted May 8, 2011 Nobody has this problem? My old PRO was much slower than any other gun around. I was running 3.8 TG to get 147's moving. Glocks are always faster because of the rifling. Link to comment Share on other sites More sharing options...
