12fpe equipment check at Worlds.
- Thread starter BrazosbyNemo
- Start date
As for the person who adjusted his hammer spring, he was told by his squad to do it and not knowing the rules perfectly he did. He told the lead Marshal on the course who is a team mate of his and he was DQ’ed.Heard from a reliable source a bit of data on the 3 DQ's of USA shooters
One a equipment failure and leaving the course w/o notifying a marshal and then trying to return .. OUPS !!!
One at chrony station during match having 3 shots to qualify sub 12 fpe, 2 over and then adjusted HST for the third try. No adjustments allowed during actual match allowed ... OUPS !!!
Third one nothing was shared .. so no idea.
Yea WFTF at a WORLD CHAMPIONSHIP don't screw around
I talked to him that night and he was not happy because he chrono’d his rifle at home numerous times with 2 different chrono‘s, just not the Air Chrono used at the match.
He took 100% responsibility for his actions, not knowing the rules in & out and came back day 2 and 3.

Another variable I noticed was that everyone including the shooters and testers/marshals handled these pellets by hand before they were weighed at the chrono station.
Oil from your fingers and foreign debris (inside pellet skirts) can affect weight. It was very dusty there.
I know because I shoot JSB 8.44 grains. I weight numerous tins of JSB before. Highest weight encountered was 8.65ish
Day three … one of my JSB read 9 grain …not trying to find blame, just pointing to a possible fault in the system.
One could argue it was a 9 grain JSB pellet due to poor quality control. My opinion (for whatever it’s worth) was that either oil from my fingers and/or some fine dust/sand got on that pellet.

Sorry my comment/observation was not meant to denigrate the quality of the event.
Garrett and his team of Volunteers need to be commended for putting on a well organized, well planned , challenging and enjoyable event.
I’m sure Garrett and his team worked with whatever resources and information they had at the time to choose the type of chrono and scale and in designing a fair way to chrono everyone’s rifle in these challenging environment.
Let’s be fair.
I think it’s unfortunate that the focus wasn’t on 99.9% of the competitors (including me) who passed chrono testing for three days. But on the small percentage of DQs that were? Skating too close to the power limit or due to competitor error.

It's far more likely that the scale was the cause of the discrepancy....or the use of the scale by whoever was operating it. You cannot weigh pellets outdoors and expect to get accurate results if you are on a flimsy portable table. You must also close the cover and wait for a few seconds for each weighing so air pressure from wind or even your breath does not affect the reading. This is all assuming the scale is even accurate and repeatable to begin with.

I don't weigh my pellets, but my FX 10.3's weighed 10.2 on days 1 and 2 on upper courses. Day 3 on lower course was 10.4. This could be weight variance in the pellet, but I feel its the scales and as has been stated, the set up and procedure if weighing. Also funny to note is that when my pellets weighed lighter, my FPS were slower? I kinda also question the consistency/accuracy of the chronographs used.

The Air Chrony is unfortunately the only approved chrono for use at Worlds.
My personal experience with one was very brief... as it was quite unreliable compared to other known reliable chronos that I had. It was small and easy to use....that's why I was hopeful it would work well.
As compact, easy, and ultra reliable as the Garmin units are ...it seems crazy not to adopt them for this purpose.

Seems weird that for such a prestigious event not to use a higher quality Chrono and I totally agree about the Garmin?!
Same goes for the scale.
People traveling from all over the world deserve the best possible chance for such things to be nearly perfectly precise.

The yearly WFTF World match can be tricky for any beginner without WFTF format experience. Best to get a good handle on the rules. Shooting WFTF Division at some local or regional AAFTA matches can help someone familiarize.
If unreliable scale or chronograph readings were the cause of a DQ, maybe there would be some recourse? The scale and chronograph readings were ultimately not the issue in this case. The one day DQ in question was a result of making adjustments on the rifle during the match that affect FPE. Check the rule book when in doubt. Second hand isn’t alway correct.
The infraction was voluntarily reported by the competitor, so it was unintentional.

True, but as far as I know, the weight and velocity readings were good for all three days. So would have had the same issue, regardless of type/brand of chronograph.
I like some of the newer radar chronographs, but not sure if they would be a better option in this case (shooting through the chronograph, into a trap only a few yards away).

Think about it for minute.....Over 140 shooters and 3 DQ's, of which one was for an electronic level on their rig. There WAS NOT a chrono or scale issue at the match. Well done shooters and match officials!
Thx

To add a little insight on weighing the pellets. They had a fish aquarium with the scale inside so wind, etc would not effect it. They had chrono‘s set up on Wednesday before the match and set up in the sight in area each morning.
I did learn something about my rifle. I put a rifle together for this event. I had never shot it in cooler weather. I had the velocity set up at 785fps with a JSB 8.44 in warm weather. I found the rifle I set up is temp sensitive (PCP). In the morning while in AZ my rifle shot as low as 723fps. The first day of the match it was warm and at the chrono test it shot 785. Day 2&3 at the chrono station it shot 760. I learned from this (other than I need to fix the rifle issue) to test your velocity at different temps. I knew I had an issue right before leaving for AZ as it finally cooled off and my rifle was shooting way low. I redid all my sight settings not realizing it was a temp issue. I thought I knocked the rifle around or something. As a result I shot great in the morning while it was still cold but things fell apart as it heated up and I was guessing on how many clicks of the turret to use.
