It was a very warm Feb. day here is Oz (Kansas) today with temps reaching the 60's, although it was windy with winds gusting over 20+mph. Not really ideal conditions for shooting and making a guys shooting ego feel good, but the temps were a gift and my son asked to go shooting. Nothing like gusting winds to serve up humble pie....lol
Shooting at 200 yards with cast bullets from Arsenal mold 257388 85 Grain Spitzer Bullets. Sized to .257 and weight sorted. Everything we shot was between 85.5-85.7 grains. Tethered to the tank with regulator shooting about 3000psi. This setup I have clocked at 1010-1030 fps.
My youngest son shooting the Texan.

Kind of the best targets that you could call "groups" We did get lucky and hit the black bullseye a few times, but it was like a blind squirrel finding a nut today.
Targets are printed on 8.5x11 sheets for reference.

Considering the wind we had today, that's pretty impressive!
I love the looks of that rifle! Is that an Emperor with extension taming the bark?
-
Thanks!
Yes the wind was rough, couldn't even hold still at the bench. It is the Emperor with the extension. It makes the rifle really quiet!!! Us and the range range officer were the only ones at the 200 yard range so no ear pro needed after he got done sighting in a new PB. The R.O. was curious about it wanted to know what projectile it was using, how loud it was without the supperssor...etc. I let him shoot it once, and he "dang" near nailed the bullseye and also pulled the suppresor off and shot one round. The quietness is very deceptive of the power. The bullets hitting the berm were kicking up a lot of mud even at 200 yards.

Apologies for possible thread hacking- but who made that stock?? It looks wonderful!

Thanks Tom!
I made it. Look through here for build photos and more of the rifle. https://www.gatewaytoairguns.org/GTA/index.php?topic=150142.100 (https://www.gatewaytoairguns.org/GTA/index.php?topic=150142.100)

200 yards in the wind? Good shooting!
I have a .257 Texan with Maddog Stock. Fun air rifle. I’ve only gotten out to shoot in once but am chomping at the bit to get out with it again.
Texan came with a bunch of cast 257420 72 grain bullets. I got the Arsenal Mold that they were made from. Best group of the day was 1 1/4” at 100yards. (Kevin shot that group) I hit steel at 200 yards no sweat, but I’d not call it a group.
My buddy Kevin, has a .308 Texan and he has a lot experience with these rifles. Warned me that I’ll need to delead the barrel after 50 or so shots and that was spot on. We both take our cleaning supplies on a shoot.
I will say the Texan is so much fun, uses way less air than my DAQs, and much less lead than the .458 and .58. Awesome accurate and powerful rifle.
I’ll probably be getting a Neal Clague shroud for my Texan.

I will have to take a look at the barrel and see it if is fouled. I did fire lap the barrel with about 50 rounds of progressively finer lapping compound to help prevent fouling.
I agree the rifle does very well with economic air consumption.

Gorgeous!! Good shooting, in the wind! That is a fine rifle you have there!!

Your gonna Love that Neil Clague. I have the first one he built for the Talon/Dors. Does a fine job! ;) 8)

good on you for Fire Lapping the bore! Don't forget to give it a very good patching for quite a while with either Flitz metal polish for final bit. Or JB bore paste followed by JB Bore bright.
Be fore Fire lapping my bore, 25-40 shots were all it could get before the fouling was an issue. After the fire lapping, and final polish with flitz, it is 200-25 rounds. Even more in the Rainstorm .250 and .257 barrels.
Re doing the crown is a must after the treatments for best accuracy. ;)

We had a pretty calm evening this last Friday and made it out to the range again to shoot 200 yards. Winds 4-5mph so not bad at all.
Shooting 86.5gr Spitzers from my Arsenal mold. Anyone ever do any trigger work on a Texan? It's kind mushy.
Data is from OnTarget software.

I want to do better!!
More practice and trigger time with the rifle is needed.
-
I am yet to delve into the trigger on my .308. I too think it is not 100%, despite a few reviews stating it is very good. I will look into reducing the creep, the weight seems ok to me, considering the hammer spring tension it is holding back.

I have been shooting tethered using the Huma external adjustable regulator. I found the big bores consume more air than the little Huma can flow effectively and with it the reg pressure drops off and then is slow to recover. If my shooting pace was quick is could not keep up with the set pressure, so would adjust it up, but then if shooting slowed or was paused then the reg pressure would go high. For me it just is not the ideal piece of hardware for tethering a big bore for target shooting.
I ordered parts and put new regulator together.

I did a bunch of shooting across the chronograph to see how the regulator performed at holding pressure and providing consistant results from the Texan. I am really pleased with the results. Here is the data from three of my cast bullets. I was not getting velocities this tight with the smaller Huma Reg. I hope this improves my groups.

Where's the line bleeder? ??? I'm looking to do something similar...
-
At the tank and if you back the reg pressure off the reg vents too.

*FACEPALM* I had a brain fart... Jeeze. Thanks!! ;D

Note that older models do not vent, I have two and the older bought on eBay does not but the new one does.
Had to shoot the rifle down A LOT to empty to bleed the line from the SCBA tank down the first time I used it, now that regulator has a bleed fitting on the out side too.

The regulator manufacturer makes vented and non-vented models. This is model 415-5000. The non-vented model is 415-5000NV.

Where did you get the parts from? I'm actually in the same situation you were with .257 and Huma.

This reg is PN: 415-6000 says it's "self venting" so should have a bleed valve?

This is the regulator I purchased.

The venting is internal and no exterior type bleed valve.

Many thanks! That's a better price than Ebay- Those are going for $295...

Was able to get out to the range today with the new regulator. It was worth the MONEY!!!
Some results from today at 200 yards. Winds 7-10.
Kind of getting it sorted out.

Nailed it!! Time to go home on a high note….lol ;D

At this point I thing my bi-pod is causing some of the vertical spread. Started practicing some different pressures on the bi-pod. I will have to try it off the bench rest support and see if the vertical spread decreases.
