On 2-21-12 I shot a brand new G17L and a 50 year old P210 side by side at targets placed 15 yards out from my bench. Each time, the guns were fired off a LTEK bench rest. I had 115gr FCAE, 147gr Winclean, 147gr PDX-1, reverse engineered 147gr Team Glock ammo, and an assortment of handloads.
The top group was fired with the Glock using 115gr FCAE ammo. Target 1 was FCAE with the P210. Target 2 was Glock with Winclean 147 TC. Target 3 was P210 with Winclean. Target 4 was actually two groups with Winchester 147gr PDX-1: the left group was fired using the P210 and the right using the Glock.
The Glock only ran factory ammo. All my handloads choked with the exception of the Team Glock load (4grs of WSF 1.100" OAL CCI primers) in RP brass. It choked on the Team Glock load in Win or FC brass.
Further, the TG load was inaccurate in both guns. All my research pointed to WSF as being the powder, but I guess it is not. The Sig ate everything without issues, and was twice as accurate, except for the PDX-1 ammo. Both the Glock and the Sig liked it.
It looks like 147 Winclean is it as far as factory ammo goes: I'm gonna try to locate some regular 147 WWB.
