bullets 155gr Speer GD and Hornady XTP

grains ~fps (average)

~~~~~GD~~XTP
12,4 ~1297 ~1310

12,7 ~1361 ~1350

13,0 ~1370 ~1367

13,3 ~1404 ~1409

13,5 ~1436 ~1443

13,7 ~1458 ~1457

13,9 ~1464 ~1464

14,1 ~1471 ~1485

14,3 ~1501 ~1496

Conditions and equipment:

- Glock 20 w. IGB full supported barrel 4.6" and DPM 3-spring system
- temp. 8°C (46°F)
- each string 3 shots only
- primers flattened last 4 strings, but nothing horrible yet

All loads very accurate, although at 1400fps started to be very snappy.

Warning: don't copycat these loads but if you do, buy the same barrel and use the best protection glasses and gloves. Anyway, most of these loads are over book max so not recommended.
