Anschutz 9003 Accuracy Problem

Post by Paul »

Three months ago, I got a brand new Anschutz 9003. Back then, I tested many lots of pellets from a machine rest and the best ones produced averages of 6.2 mm for 10 shot groups. Now 3 months later, these same lots, tested with the very same setup average almost 8 mm. Do you have any idea of the cause of the deterioration in accuracy ?

if its brand new - did you clean it first? as this could effect accuracy as could lead in the barrel

Other than that it could be that the barrel has worn in a little (in a good way) and rubbed off all the cutting marks now

how have you stored the pellets? have they oxidised?

Give it a good clean, torque it up, chrono it and test again and see how you get on

That's almost exacly what I did (I don't have a chrono) but unfortunately...I can't get back to 6 mm.

ok - shoot about 50 pellet though it, pull a dry pull through, through it and then test it again and see how you get on

batty,

I followed your advice and did the test with a good lot of Qiang Yuan Match but unfortunately, it didn't solve my problem.

Average of this lot when rifle was new: 6.3 mm
Average of the 5 groups (5 X 10) during the test: 7.2 mm
Average of 3 groups after cleaning: 7.8 mm

i'm thinking it could be time for a service/sending back to the manufacturer/seller
