I had a chance last week, a lull in the storm fronts moving through....nice, warm day, 60 degrees and dead calm.....I called a buddy of mine that has a rock-solid shooting bench, spotting scope and 150yds....but he didn't get home until 3 PM, so I weigh sorted and head sized a tin of JSB exact kings, checked everything out, shot some spinners and just got to know the gun better...

I haven't done anything to this gun out of the box except put it in Michael Chavka's masterpiece of a stock, moved the shroud forward, added a spacer at the back and two more baffles, reshaped the bolt probe a bit, did the trigger mod and adjustments, cleaned the bore, verified the tightness of all the bolts and screws, put a Hawke 4.5-14 tactical on it and have been running pellets and air through it at the cyclic rate....and I thought I was impressed with the .22.....this one's accuracy is a thing of beauty....and I haven't had it across the chrony yet or worked on it's consistency....

I got there, got set up, shot some groups at 50, then 75 and 100yds.....and was thoroughly impressed...without the chrony data yet, at a 3000psi fill, the gun starts low and climbs for the first 5-6 shots, then levels out for about 4-5 shots into amazing accuracy, then starts to drop....again, this is at 100yds, so any inconsistency will be immediately seen...at 25yds, this gun will put 24 shots into one pellet-sized hole, at 35yds, it will shoot 21 shots into one hole, at 50yds it will put 12 into a .395ctc group....75yds results in a full mag into 1/2 inch...

Now, at 25 and 35yds, it will put them all there from shot #1....at 50, on shot #5 it climbs up to center and stays there for 12, at 75 it starts at shot #5 and stays for 8.....at 100yds, it climbs up the target and lays 6 of them on top of each other before it starts to drop.....

After running numerous mags and fills through the gun, and totally wowing the hell out of my buddy, and stupifying his 65 year old father with my 'pellet gun', my spare tank was down to 2800psi....which I'd intentionally not filled for th purpose of trying this gun tethered....I tried this with my GD .22 and the results were not as good as fillng the gun and shooting it through it's sweet spot for some reason....

The .25, untuned however, was a different story altogether....the first 3 shots were not promising...and I'm not sure if the check valve needed to adjust to the constant charge, but they marched up the paper and settled right down...

This first pic is of a fill at 100yds...the one out the top was all me...had to add about a pound back on the trigger...i'd lightened it to ounces to bench it....but I'm used to about 1.5-2 lbs.....so ounces wasn't cutting it....I threw it up out of the group, but you can watch the group climb the paper, and settle into the sweet spot....



One thing I noticed with the gun was that it shifted POI to the right when I tethered it...don't know what that's about, except perhaps the larger volume pushed the tube somehow...the hose wasn't applying any tension...so after the first group, I moved the scope over a couple of clicks...this a full mag..



I shot probably 40 groups, but here are the best of the bunch...I'm going to add some of Greg Davis's goodies to this gun and play with it a bunch....the .22 is amazing....I'm expecting this one to be purely astonishing....Harry, I'm hoping this thing will run all the way to 200yds!

These are all one mag with the exception of the last two, they are 4 shots each..but out of the same mag...






This gun has the most long-range accuracy potential that I've had the pleasure of shooting so far...no, it doesn't have the smack of the Career or the Ranger...but I'm betting once I'm done tuning this thing, I'll run it against any unregulated .25 cal on the Market...

I don't know, but you may be the first to get sub 1" groups with a Crosman barrel at 100 yds? I had a Crosman barreled Career that shot dozens of 1.25" groups at 100, but never got the magic 1".

Is that a longer barrel than stock? I saw the pic in the other blog. It appears to be longer.

Tim or LD have done it and haven't said anything....I know Greg Davis has gotten very close, if not accomplished it with some of his tuned guns.....that being said, I'm just the one with the big mouth...lol! I get tired of the Crosman bashing that goes on, and I wasn't a fan of them growing up with a Sheridan Silver Streak, while all of my buds had Crosman's and Daisy's......mine was hands-down the beter gun....

But, all of the products that I have bought or tested for folks in the last 3 years that had the Crosman name on them have been exceptional pieces for mass-produced stuff.....their customer service is just simply amazing, and they're doing their best within an R&D budget to bring us what we want.....I have nothing but the greatest respect and admiration for an American company that will do that....

2.70 inches to accomodate 2 more baffles to make it twice as 'backyard friendly' as it was out of the box.....my .22 will look like this shortly too....I've got a 2.7 inch-longer LW barrel on the way for it...although, the LW barrel is going to have a tough time outshooting the Crosman barrel that's in it....the .22 will hold MOA at 100yds....just haven't gotten down to the Sub-MOA with it yet...lol....the heavier .25 pellets make it easier to do IMO.....

Thanks for the response Jamie! Is there somewhere I can read up on the modifications you made? I wold like to set up a gun exactly like yours. I do a lot of varmint tree rat hunting and would like to use an air gun at longer ranges. I am fairly new to this game, sorry for all the questions! And thanks again for your help!

Great write up but I am not sure "Out of the box" really fits.
