EVOL HPS 30 HPS thoughts

You get a 10 when your projectile cuts the 10 ring and you get an X if you take out the center dot. Keep in mind there are two conventional scoring formats: best edge and worst edge scoring. N50 uses best edge and ARA uses worst edge scoring. Best edge is more forgiving and used more often.
 
Thanks guys!! Either way I am going to have fun. Heck I am here inside my house shooting the Paradigm in .22, and man what a difference the caliber makes!

A 10 is the ring and an "X" is when you touch the center dot. The more "X" is better than a standard 10. Typically the "X's" are used to determine a winner in the case of a tie.
 
OK report time!!!!

I was able to shoot 7 shots before I had to stop.


Ok report over.. lol .... just kidding.

I got to the range about an hour and a half before the shoot to help set up and get things ready to go. When we had around 5 shoots, everyone that dared to come out in the cold, we opened the range and started the zero time. I took up a prone position and verified my zero. I was around 2 mils low due to the head on wind as well as the extreme cold. So I made my adjustments and shot another mag to confirm. Got the typical ragged hole at 50 yards and everything was good to go. So left the rifle on the line to make sure everything was acclimated and ready to go.

After around 15 min or so we started shooting. I was the second shooter so the rifle sat on the line for 2 or 3 minutes to let the first shooter go. After he was done I grabbed the rifle and took my position to shoot the stage. When I loaded the magazine and held the rifle pointing up, with the breech next to my ear I heard a faint hissing! So I told the match director for a seconded to listen to the rifle and sure enough there was a leak. I found the leak at the connection between the air cylinder and the receiver. I was given time to go back to my truck and fill the rifle back up and make sure everything was ok.

I aired up the tank, took a few blank shots to make sure everything was seating correctly, and topped off the tank. Back over to the stage and the match director told me to go ahead and shoot. Same as last time I loaded up the magazine and and took my position. Rifle pointed up ready to go and I could still hear the leaking air. Said to heck with it and I am going to shoot and see what happens. I was able to get 7 rounds off before I called it quits, I was able to get 3 hits but just barely.

I packed things up and warmed my truck up and headed off. I was able to talk with Tom about the gun and what happened and we have an idea on what the issue was. The rifle has been warming up for about 5 hours now and is up to room temp, so I just got done shooting a full mag through the rifle with no issue. Air was down to around 1000 psi, so I aired it back up to 4000 psi and I will be watching it to see if there is a leak......or if it was just to darn cold for the o-rings. Talking with Tom there is a double o-ring on the base of the air cylinder to prevent leaks. I believe he mentioned a 70 and a 90 durometer o-ring stacked. The softer ring is in front of the harder ring. This helps the softer ring seal against the stiffer ring to help prevent leaks.

Tom is going to be looking at the operating range of the seals, as we are both sure that -20 is well beyond the operating range. The plus side is that the cocking motion of the rifle was smooth as silk and didn't pose any issues. The regulator functioned great, the hammer was smooth and didn't seem to hang up. Other than the air leaking there was really no other issues with the rifle. It was EXTREMELY COLD and hard to hold onto the rifle for sure, but a good set of gloves was good.

I am going to head to the range next week to confirm that everything is ok and will get with Tom to let him know as well. If everything is ok, I am working on taking the rifle out hunting next weekend.

thanks for the update boss!
a real bummer thing didnt as planned but that crap happens.
i stuggled with scope issue all day and finaly gave up send this gals in i am tired of screwing with it.
 
Woogie, I spent many days of my youth setting up the ranges for different shoots in all kinds of weather. Good on you for being out there in the elements helping. As far as those o-rings go, I use Krytox GPL205 on all o-rings to help with sealing in all kinds of weather. Some say they don't need lube, and it may not matter where they live. But in the frigid north, every little bit helps. Stay warm and aim small.
 
Thanks for the report. It's good to know what can go wrong and why, and the fix. Maybe just keeping the gun warm with disposable hand warmers wrapped on with ace bandage camo tape would work too. Has anybody tried to fight the cold, instead of just putting up with it? Something to try I guess.
 
Typically when I am out in weather like this I will be in the trees and out of the wind.

I am glad I was able to get out there and do some testing to see what will happen. That is what Tom was wanting and I am glad I was able to do the testing.

The cold really doesn't bother me to much as I have lived up here for the majority of my life. Like I told Tom in our conversation, it takes a special type of stupid to live up here. Heck we do all sorts of stuff in the winter and have the needed gear for it.

I have tried this with my RedWolf when I had that gun. While it did work, those hand warmers get quite warm and I was always worried about damgaging the epoxy of the bottle. The other option would be to figure a small heating pad that you are able to adjust the heat on. Then use a small battery pack to keep the thing running.

I do have a pair of heated socks that I could see if they would fit on a bottle gun. Wonder if I could find a replacement heating pad and make a custom sleeve for the rifle. hmmmmm
