RAW REPORT

Just found it interesting that you stated 3 shots in same hole. Then two shots wander.
If that would be consistent, just wondering if it suggests a velocity change.
there is no velosity change as statted my e.s for 130 shots is less than 10 fps and my standard deveation is just 1 fps.......... im getting 3 ou of the 5 shots through the same hole with a 177 cal pellet and the other 2 shots are only a few mm away and this is out doors groups.....this gun is extremmy ccurate with jsb 13.4........ i would considder 10 mm groups out doors with a 177 match grade accuracy... im getting 3 through the EXACT same hole out of the five and at 55 yards im getting 3 out of the 5 still touching.........i dont think u can ask any better out of a 30 cal let alone the little 177 out doors in the wind... the pic included is 10 shots out doors in the wind at 25 meters laying prone on the ground this is with barrel indexed with the rotation it likes with this paticuar lot of jsb13.4 absolutly out standing accuracy with any air gun

Yeah Scott,
Shooting 15.89 at about 910 fps; at 50 yards they can do 3/8" groups ... out to 100 I've had nothing but a shotgun effect -> puzzling?
Must be a speed issue?
If there starting to sprial as they get further out .. TRY slowing them down to 850-875 as too reduce there RPM & see if they stay stable further out ?

yes very acurate and this accuracy is not even fine tuned with finder fps adjustment or fine tuning thimble adjutment.... this barrel is even more accurate with different lots and different thimble /barrel rotations.....i dont believe i coul find a finer air gun for bench rest shooting for the distance this gun was made for...it makes me smile every time i sit behind it. this was a 27 .5 yard group...... im almosr certian i can do this at 40 yards.... im almsot to that poing now with out fine tuning..... remeber this group is an out door group lineing prone on the ground... if this gun were indoors on a fancy rest it would be fairly easy to get 10 shot 1 mm groups with this gun........ out doors im almmost getting this now...... i feel i got lucky and got a really good poly barrel.. mabe even an exceptiona one

Its never a good idea to support the front of your rifle from an air tank (IF) you are looking for optimal accuracy. Use the stock fore end or pic rail.
Thanks but I have no intention in supporting the rifle by the tank, I am printing a bag rider that will be attached to the MLok rail on the bottom of the stock. I just want to make sure it’s wide enough to go around the tank.
 
the tm and bm are single shot only.... it cant take a mag..... and the hm cant take a thimble.... cause if it did you cant use a mag in it
Hey aa,
If you have questions, just call Martin at Airguns USA. He will be more than happy to help, after all ..... he designed the guns.
