Hi Taisto,
last weekend we had a kinda "matchtest" of the personal challenge the TS posted.
During the CESO 2012 http://www.puskaslovesz.hu/s/main.php?gr= at stage 10.
Start position, standing on a small platform (about 11/2 foot width, 3 foot long) hanging on chains. (very woblie!)
Shotgun option 3 held in both hands, stock touching hip and ofcourse triggerguard downwards.
4 plates (2 leftside of bay, 2 rightside of bay) in the backstop 3 minipoppers standing between and besides no-shoot poppers.
Distances about 8 - 15 meters.
Basicaly all competitors loaded 8 rounds.
Fasted three times on that stages:
Standard : 8.39, 8.96, 9.05
Modified : 9.05, 9.24, 9.59
Standard Manual : 8.08, 9.03, 9.72 ( that was me )
If estimate the time needed to shoot the targets, splits&transitions you can calculate the loading times.
Btw, top 3 didnt include finish shooters but ofcourse not all of your topboys were there
See you soon (Bulgaria Rifle??)
Greetings
Adrie
