am a fairly new loader and have ran into a bit of trouble regarding 9mm load data. seems 124gr XTP runs little wide and my Steyr M9 does not like it when seated to the suggested length of 1.150" bullet hits the rifling. I have toyed with seating depths and COL's seems the 124gr XTP will not hit the rifling when the COL is 1.125-1.127. I have no problem at all with Hornady 115gr FMJ round nose loaded to 1.150 and looked at some other cartridges my gun has shot winchester 115gr whitebox FMJ&JHP,speer 124gr FMJ,CCI blazer 115gr,S&B 115gr FMJ,UMC 115gr FMJ.
at moment working with power pistol powder though all data I have is Lee's speed die paper,deluxe die set paper,modern reloading book and alliants web page data which list 124gr jacket bullets COL to 1.150. oddly they list 115gr COL 1.120. I measured the hornady 115gr FMJ and 124gr XTP the XTP is + .005 taller.
think it would be okay to use 115gr data at 1.125 with 124gr XTP would leave same internal capacity as 115gr maybe back off loads some slightly below 6.0 gr work up? also keeping eye on gr data for 147gr though thats 1.140 OAL not messing with 147gr bullets but read somewhere when dont have data start with heavier bullet data work up something like that anyway.
anyone have any other data. have done some searches seen some issues with CZ pistols saw some people going to shorter OAL. I havent toyed with changing OAL's I know the basics further out less pressure further in more pressure
bring the OAL lessen powder. again powder at moment is POWER PISTOL.
on another note does anyone know what OAL winchester's website data uses? see they show 1.169 max didnt bother to include it elsewhere and have some Win Super Field would like to use eventually.
appreciate any help.
