just got a used a4 it isshooting very erratic pulling to either side at any distance the marker reads at 200 at the flash chamber and just under 50 psi at the lpr will adding shims to adjust the lpr to 82 solve the problem or should I be doing something else thanks

what kind of paint are you using, and what barrel. also what is the dwell at?

[quick7]

dwell is set at 11 was at 14 boomstick barrel and eliminator paint shoots fine in an allias

[PB 4 Him]

try putting your dwell at 9 and input pressure at 250

[quick7]

will do thanks

The LPR at 350 psi input should read 80ish psi; but when you bring the HPR down to chrono correctly it should read about 65 or so. (50 is a litle low, but it's not likely the problem) The LPR pressure depends on the input pressure.

bolt looks warn so ordered a new one but could it be my mini reg?

Doubt it: I bet it is a barrel issue. Is the bore of the Alias barrel the same as the Angel's? What kind of barrel is on the Alias?

[quick7]

angel has old style boomstick690 bore alias has pepper stick 689 the boomstick came with the marker and looks well used ordered a barrel kit last night thanks for your help and time
