This is what a hot load of DoubleTap will do...
DoubleTap 10mm
135gr JHP @ 1600fps - 11.0" / .70" frag nasty
155gr Gold Dot JHP @ 1475fps - 13.5" / .88"
165gr Gold Dot JHP @ 1400fps - 14.25" / 1.02"
165gr Golden Saber JHP @ 1425fps - 14.75" / .82"
180gr Golden Saber JHP @ 1330fps - 16.0" / .85"180gr Gold Dot JHP @ 1300fps - 15.25" / .96"
200gr XTP @ 1250fps - 19.5" / .72"
230gr Equalizer @ 1040fps - 11.0" and 17.0" / .62" and .40"
Here is a complete list of factory 10mm loadings with energy, velocity, price etc. Sadly not too many available in Kanada!
Did you chrono your loads?
What kind of brass were you using?
I only use
NEW Win or Starline for
hot loads.
I never reload once fired brass
hot...I keep it for target loads.
I have tried AA#9, BlueDot, and 800-X for my 10mm's.
I have come to conclusion that 800-X is one of best powders for speed&energy but does NOT meter worth a crap. Bluedot is great powder as it meters consistently(I use this powder for my target loads).
I have never tried andy Vihta Powders but this guy was pleased with 3N-38 in his 10mm.
So you may want to try that powder as well.
Quote from G-20er on GlockTalk...
Here is the data using VV 3N38 and the 200 grain XTP Bullet. Anybody ever seen a handgun load with a 4.2 on standard deviation. That is great!!! This was the most accurate powder I have used yet. All 10 rounds were in a 3 inch diameter circle from 25 yards using open sights and a rest on barrel side of gun only.
G-20 with stock length KKM barrel
Starline Brass
CCI 300 primers (do not use mag primers with this powder).
OAL 1.250
Please Note: do not try to fire these loads in a stock Glock barrel. 9.3 was max load for the stock Glock barrel. See bottom of page for further information.

Maximum safe load with stock Glock barrel was 9.3 grains of VV 3N38 at 65 F OAT. This load produced only 1135 fps. 9.5 grains don't even try it with the stock Glock barrel. Very heavy smileys on all cases. I believe this powder was actually designed for lighter weight bullets in mind.
Maximum safe load using KKM barrel was 10.5 grains of VV 3N38 at 65 F OAT. This load produced 1221 fps with a SD of a low 4.2 I took the load as high as 10.8 but got light smileys on 75% of brass. 10.8 grains of VV 3N38 gave 1252 fps which matches DoubleTap Ammo; however, Mikes DT Ammo is running at much lower pressures and much safer.
I am learning that with the KKM aftermarket barrel with powders in this burn range, you can load 10% more powder which gives you approximately 110 fps more with same pressure signs as compared to the Glock stock barrel.
