I finally got to shoot my new Katana a few days ago. Weather was not the greatest - about 50 degrees and some light winds. Made for some cold fingers!
21.2 gr Beeman Kodiaks, starting at just over 2000 PSI:
Ending pressure was 1000 psi.
For 30 shots, average MV was 709 fps and ME was 23.5 ft lbs. Max was 720 fps and 24.3 ft lbs. Nice 23 shot string (#3 to #25) that varied only 12 fps.
Best 5-shot group was .6" ctc at 50 yards. Accuracy was good until the last five shots; that group had some vertical stringing.
Also shot some 14.8 gr Beeman FTS pellets; accuracy was almost as good as the Kodiaks; velocity ran from 808 at 2000 PSI to a max of 845. Most varied from 820 to 837 once the valve lock was passed.
A few 25.3 gr JSB Monsters gave about 645 fps but poor accuracy; will do more testing with those.
Overall the shot-to-shot variation was usually under 5 fps for all of the pellets tested. The trigger is also very good. You can argue about the looks (wonder who made the call on the action inletting) but not how it shoots.
I wouldn't mind owning one of these rifles. It's a Discovery with a "nicer" stock and the Marauder's adjustable metal trigger assembly. Lightweight and very accurate too from reading the OP. I would alter the stock if I got one; mark the centerline of the resevoir tube, plane the top down to that, shorten the forend a bit and round it off. No more inletting gap, no more top heavy or too long look, no more difficulty with the bolt handle being so close to the wood.
those results are really good, and with some pretty heavy pellets with plenty of kinetic energy or ft. lbs energy to do the work once it gets there..14.3s would be faster for those few who may not take that into account on first blush.
I for one am glad to see this post about a gun that I knew nothing about and am impressed with due to your post.
please give us more information as you develop it.
Q\ : are you thinking of using the 18 grain pellets for it should accuracy prove up to your specs ?
q : what other pellets are you considering ?
thanks for the review.
Yes, it is exciting. I also have a set of Crosman bulk-fill guns to test - a 111, 112, 114, 115, and 116. I need to do seal work on all five and I am looking forward to being able to plink with them this summer. Still looking for a 113.
Cold here, too. Lows in the 20's until at least next week.
