Katran .22 Cal Long 520 mm barrel

[crazyhorse]

Ordered the Katran from Utah Airguns March 28 and received yesterday. Put it on the chrony and here are results right out of box:

Shooting JSB 18.13 GR :

LO 935.5

HI 934.8

AV 930.2

ES 9.30

SD 2.82

There are many neat features designed into the Katran and one is the magazine is below the scope rail. Today I plan on sighting in and constructing a range card. Squirrels are running all over my property and time to reduce the population.

I will try to post some more data and pictures later.

I'm not certain how you got that average muzzle velocity with the high/low velocities you state, but point taken.

The Katrans definitely have an interesting mix of features with great magazines and triggers, high power and accuracy, and a nice design and build.

Congrats on your new gun. Your local ground squirrels are going to hate you soon!

I shot 9 shots but only posted a couple. They say you can get correct results by shooting three shots on regulated rifles. I've always done the same for all my rifles except the non-regulated air rifles.

I would say low was 925.5, which would fit the es

Congrats on the new rifle!! I’ve been eyeing the Compact. I’d love to have one tuned to 20fpe. I’ve got a Caiman X & it’s a shooter for sure. I turned the regulator up just a tad & it’s pushing Jsb Knock Outs @910fps. Took a squirrel just the other day at 108.4yrds.

I sighted it in this afternoon got on target in four shots then got a group at 3/8" with five shots at 25 yards with all touching. Funny is when I checked the trigger pull it was 2.9 oz...waaaaay to light for me so need to get it closer to 12 oz.

Wish I could get pics up the site I was using is caputs right now.....

OH OH !!!!

I was looking over my Katran when I spotted metal shavings between the barrel and air tube...looked like teeny weenie gray hairs LOL...SO i checked my Avenger which I filled to 3600 psi just before I tried to fill my Katran....more shavings...same goes for the DAR but not near as many metal shavings...(very small)
.
Gentleman my Umarex Ready Air is getting ready to take a major dump. I also checked my hand written time log that I started a year ago and fill times have been slowly INCREASING over time...from 3 min to 8-9 min until it took 42 minutes to fill the Katran to 200 bar this morning.
Now I have to clean 3 rifles tomorrow while the squirrels are playing in my back yard. LOL.
Been reading a compressor thread and I may purchase one of those disposable Amazon compressors. LOL



This is my Ready Air...one year and it takes a dump....On my log i noticed it was gradually increasing on fill times for the same rifles I was topping off. So i suggest everyone watch your data. Compressor temps were constant at 100 F- 105 F so that did not seem to be an issue.
