Just chronoed my G20C

[Mercury0_0]

The data below was chronoed with a CED M2 chronograph. The data in black was from a Glock G20C, the data in blue is the same Glock with a .40cal non-ported Stormlake barrel, the data in green was from a G17, and the data in red is from the Desert Eagle .50AE.

How much farther do you think I can push the 10mm 180gr XTP's? Or should I push it any farther? Is 1200fps good enough for your average handgun hunting, bear defense kind of thing? There were no signs of overpressure like smiles, flattened primers etc.
The .40cal was just some extra reloads I had left over. I'll be making up a proper load to make IPSC Major. Same with the 9mm.

I have seen the XTP's pushed as fast as 1400+ out of a 6" SL barrel. Camp Cook is a good guy to talk to for high-end loads. Try glocktalk as well.

Yep, I've posted on Glocktalk and 10mmtalk too. There are a lot of very smart guys on these forums, and it usually pays very well to listen to some of them before pushing the envelope. What an incredible resource internet forums are. Of course, you have to weed out a few crackpots but overall it's worth it.
