The Match will be shot at 25 meters using the World Benchrest 25m target. If you have an air rifle with a wooden or synthetic stock with no adjustable components in .25 caliber or less, 35fpe or less, and some soft bags for rests you are in. Rifles that qualify are Marauders, Rapids, HW100, FX Royale, Cyclone, BSA's AirArms S400/410/510s, Daystate Airwolfs, Mark 3's & 4's, Huntsmans etc. We will also be having an Unlimited 50 Yard match if we have enough time and shooters for the Class. The only requirement for the unlimited match is the rifle must be .25 caliber or less. Descriptions of classes below.

If this sounds confusing and you have an air rifle and would like give benchrest a try or you are just looking for a place to shoot your air rifle come on out. We can shoot out to 200 yards so if you want to see what kind of legs your air rifle has join us.

I'm going to try to make the BR shoot next Sunday.  I had a great time last fall attending 2 of them.  Its a different discipline from FT, but reading Ione's tricky winds is practice that will go toward my FT shooting's improvement I hope. 

See you Sacramento area guys there!  ;D

I'm in for 75 shots each in BOTH Light and Heavy varmint class's.
CYA all Sunday  ;D
Title: Lots of fun and every educational!

The match was more like Shooting in the Wind 101. Absolutely fun stretching the leg of an FWB 300S to 25 meters in somewhat windy conditions. I know Ione, CA can get a lot more windy, but today was mild enough for beginners like myself, but yet still windy enough to learn reading wind wanes.

I agree with Calmark and Motorhead that BR is helpful because it helps to remove almost all factors except for wind. Hopefully, I can apply what I learned today to become a better FT shooter.

Everyone was very friendly in the match and freely shared ideas and experience, I learned a lot just from eavesdropping conversations  :o! Thanks to Jim for organizing the event!

As I forecasted, it rained in Fairfield until, about 1:30pm.
I did get some FT practice in afterwards.
you certainly had some nice sun there from the looks of it.

The day turned out to be a nice one!  It was great to get out and shoot with a bunch of other airgun nuts for the first time this year. 

The top picture is of the guys performing a "firing squad" on a hapless soda can.  It got walked from 5 yards all the way well past 25 yards and ended up looking like swiss cheese in the process! ;D

The can ended up 52 yards out ;D
Title: Why tail wind drops the POI
Post by: sactargetshooter on April 28, 2014, 11:02:49 PM
I think I have this figured out. Maybe.

According to Chairgun, tail wind should raise the POI at least for my rifle at 25 meter. However, experience at the range is exactly the opposite. Furthermore, even with 20 MPH wind, the POI should only shift a little bit, not the observed amount during the match.

I think this is why.

Tail wind at the range has to mostly go over the cover structure. As such, there is a small vacuum developed right in front of the benches. This not worthy air moving over the roof of the cover structure down, possibly creating turbulence in the process. With very strong tail wind, I think the turbulence may get past 25 meters and does not shift the POI significantly.

The same probably applies with side wind because the range is surrounded by mounds. This gets even more tricky because lanes that are closer to the mounds experience a different turbulence compared to lanes that are further away.

Matt was absolutely right regarding being able to read wind that is blowing downward.

Posted on behalf of Jim C

Well we had 10 shooters come out & brave the questionable Ione weather on Sunday.
Light breezes that shifted threw out the match kept us all on the game of being good dopers ...  ;D

Some pretty darn good scores were posted with Tak and his FWB 300 showing power means squat when you got accuracy and an able shooter behind the trigger.

Anywho ... how the cookies crumbled when all was said and done.

It was nice to meet up with several other GTA guys at the Bench Rest.  I think the results of the match were pretty good, even with shifting winds to contend with.  ;D  I did also notice many shots dip low and I think there is something to that theory of winds rising over the roof and dropping down and pushing slow-moving pellets low.  I used 7.3gr JSB RS in my 7ftlb FWB300S mini and the wind sure did toss some far off my aimpoint.

Thanks for adding in more pictures, Jeff.  I was so caught up with things I only remembered to take the two Niko posted.  I guess we need to bring eggs next time for Frank so he will come and shoot with us.  ;D

Post by: JEFROX on April 30, 2014, 11:29:05 PM
Good scores by everyone! I don't know how Tak did it because when I tried his 300S, my POI was an inch and a half lower than my POA! With such a low power, I could see the pellet dropping at 25 meters! He truly has the skills and can shoot that rifle well! :)

I usually take lots of pics - something that I do whenever I'm out with my kids. Hopefully you guys don't mind me snapping pictures every now and then. I'll try to take more pictures next time to share.

It was a lot of fun for me even though I didn't turn any cards in, I wasn't mentally prepared and besides my guns did compete but in someone else's hands ;D

Post by: sactargetshooter on May 01, 2014, 04:55:11 AM
Jeff, thanks for the kind word!

The FWB 300S is very self-consistent even with unsorted JSB Express pellets and a $90 duplex scope. Compensating for wind is really the name of the game on that day. I was shooting next to Matt with his really fancy wind indicators, that helped a lot!

Now that I know wind plays such a significant role shooting in Ione, I think I am going to invest in some wind indicator myself. Already have some idea of how to make a few DIY units for BR and a portable one (attached to rifle) for FT.

I'm new to this parallel universe. Darn if I didn't have a family commitment that took precedence over this meet. Otherwise I would have been there watching, drooling and pestering everyone with newbie questions.   ::)

Is there some sort of air gun shooting organization in the southern Sacramento Valley?

Post by: sactargetshooter on May 01, 2014, 12:00:16 PM
Thanks for the kind word, Scott! I learned a lot about the effect of wind on slow and light pellets that day. As you said, it was the best way to learn how to shoot more effectively in FT matches (and other shooting situations!). The FWB 300S is very consistent by itself, and as such, a good learning tool.
Title: Re: Sacramento Valley Airgun Benchrest - Sunday April 27th, Ione, CA
Post by: sactargetshooter on May 01, 2014, 12:12:12 PM
I would like to share a little more about shooting on that day  ;). This may or may not work with you, YMMV!

I shot with both eyes open. Right eye to aim, and left eye to keep an eye on (Matt's) wind indicators. Wind direction was changing so rapidly that it could change between sighting and pulling the trigger. I think this helped me change my POA a few times just in time.

It was actually easier to correct for strictly cross wind compared to tail wind! Given the same cross wind intensity, the pellets drift pretty much by the same amount. In the strongest cross wind, I had to put the POA one full circle from the bull's eye.

Tail wind did not always drop the POI. I think the drop of POI was not proportional to the intensity of tail wind. There was an "optimal" tail wind intensity that dropped the POI more than lesser or strong tail wind. Don't know how to quite quantify that, yet.

Wind indicators are very helpful! I'll make some for the next competition. According to Chairgun, tail/head wind should not have much effect on the POI at 25 meters, not nearly as much as cross wind. However, quoting Matt, down/up draft was significant at least at this shooting range. That probably explains quite a few misses in the FT matches!

Hope someone finds this useful for the next match.

I was shooting my FWB300 at the very end of the line of shooters, the farthest from the wind indicators.   I noticed that you couldn't always trust them from my position.  I saw several shots go the OPPOSITE way as the indicators showed.  Since I'm shooting slow speed and feel no recoil, I could watch many pellets strike the targets and definitely saw more than a couple go the wrong way.  Only after a few moments would I start to see the indicators catch up to what I was seeing on paper.  As you can imagine, that made things pretty tricky.  I should have taken more sighters between targets to test actual conditions more often.  At least I know now not to believe all that I see unless its right where I am.  ;D
