Guys I went out on Sunday to try some 200grn XTPs with my Glock20 Gen 4 with Barsto barrel and 22lb spring. I had 0 problems with my Winchester brass as per bulges etc.........chrono battery was dead when I got to range so no data on how fast the loads were but have pics below....thinking the 9.8 of LS will be that load. These were shot at a little over 15yrds!!

I wish you would have had a spare battery! ::) It would have been great to see the numbers from the Bar-Sto barrel.
Based on test I have done and 9.8 being on the higher end with 200XTP's (mimics the SwampFox loads fully supported chamber) the velocity would be in the 1300+ fps range. :o
We generally shoot every Sunday. I'll be loading up for the weekend tuning for a custom rifle and will shoot these same loads thru the chrono then......stay tune!
1300 fps for a 200 grain is one heck of a load! Sounds great!!!
I'm trying to decide whether to get a 6" KKM for my G20SF or to splurge on a Barsto 6" semi-fitted barrel.... I've owned both companies and both stock and 6" lengths but I'm still not sure of the extra money is justified, especially since I have a red dot sight on my G20 now which makes even the stock barrel super accurate.
I do concur, though, with Shadow. 9.8gr LS under a 200gr XTP will surely get in the 1300fps range as 9.4gr under the same bullet from a 6" barrel gets me 1325fps.
Nice groups, sir! Enjoy! That load is a hammer.....
:o :o wow that load is a hammer for sure :-\. I stopped at 9.4 of long shot and was in the mid 1200 fps with my KKM 4.6 inch barrel. It's also extremely accurate to boot. ;D.
You have for sure found the hammer of thor
