Here's a long explanation for a fast shoot
I recently went to Oregon for their Extreme benchrest and EFT and had a great time, but learned a coslty lesson.
The first morning of the match, we had 30 min for the 25 targets. The winds were switching very quickly since 2 valleys merged into 1 where the range was located. About 2 switches every 5 seconds ..tough one's to read. The first day, i was on bench 3, close to where the announcements were made. The match was a difficult and i made some mistakes on wind calls, but i did learn from it and was ready for the next day.
On the 2nd day, i was on bench 18 out of 20. Besides the fact that i am deaf on my left ear, i never heard any of the announcements made that morning. When the match started, i had a bit of trouble with my regulator. I lost some time fixing the issue, but i still figured I had plenty left. Well, I would have had plenty if we were going by the same length of time. Unfortunately, an announcement was made that the matches were going to be shorten by 10 minutes because we finished so late. I never knew about it. I was taking my time and waiting for my conditions. Finished up on the 2nd row when i hear.."2 minutes left" ?!?! WHAT THE !!!! I panicked! I use a single load, and i didn't have a magazine on stand by. I am trying to load and shoot as fast as I could. Pellets are getting scattered all over the bench....it was a mess. I ended up 2x shooting 3 targets and became a spectator on Sunday instead of shooting.
I usually single load, but after that experience, i now have a mag loaded on the side. I wanted to see how I would do if i had to rapid fire some targets if ever that kind of time constraint again. The targets were shot 1 by 1 ..no grouping at an indoor range. 100 yards. The target is a full size EBR target, but only showing out to the 7 ring The whole target took me less than 2 minutes, so I realize I don't have to panic if i get into another time crunch.
Have a great evening friends. Almost forgot, FWB300S 10 meters off hand
