JSB .22 Test Tin Results…

[tim2734]

So working through the mine field of owning a new to me, and first PCP; naturally one of the experiments is what pellets its keen on.
So a good barrel clean, a bit of leading in with some cheapo pellets hanging around, and below are the results from 6 different JSB’s.
Ok so there’s a couple that really stand out as a good match, otherwise it’s a bit difficult to decide but think I’ve narrowed it down to 3 through to the next round. Make of it what you will…. H&N’s next.
Hatsan AT44-W10, 25yds, BR, indoors.

Try some JTS, I got one hole grouped in my Rapid 7 FAC at 35 yards & several there’s rifle did the same at 25/30 yards

Just based on the JSB's - it didnt group as well with the slightly heavier pellets. I see the JTS are 16gr upwards. Good price though!

Myself and my best mate both shoot .22 class in hft, so we’ve tested loads of different .22 pellets over the last few years, we both recently gave our barrels a light polish as there were a few tight spots and mine had a really tight choke. What a difference it made. The guns are now quite pellet unfussy and my mates shoots the lighter jsb rs well where it hated them before the polish. Also different dies/batches of jsb will shoot differently, even though they’re the same pellet as such.

I've only had to do it to one gun out of desperation, luckily it was a cheap chuntsman Chinese daystate clone. I couldn't believe what a difference it made, turned out to be the least fussy .22 barrel I have & matched my son's blueprinted R10 with a replacement 15" barrel JB hand selected & prepared FOC as it's original 12" one would only shoot ftt's decently.

Sorry to sound ignorant as I'm a newbie, but what do you mean by a tight spot? When I cleaned my barrel, there was definitely a section of the barrel that was noticeably tighter to pull the cleaning 'pull through'... through. It definitely disappeared after a few wipes though.

That's just where heavier lead deposits were, he meant a tight spot after cleaning in the barrel bore itself.

It’s where the barrel (other than the choked area) reduces in diameter, polishing the tight spot out help accuracy and as said, makes the rifle like more/different types of pellet… in most cases

You need to push a pellet through the barrel by hand, feeling for contact all the way to the muzzle where it should exit effortlessly.

If there is resistance, other than the choke near the muzzle, then that can be relieved by polishing.

Be careful of fixing faults that don't exist.
