Re: What pellets are everyone using

Different preferences for every gun and application. My AA and HW PCPs like JSBH some in 4.51mm some in 4.52 mainly for long range hunting or breezy conditions. Not for springers though - using JSB/AA 8.44 or 7.87gr.

Re: Range master sovereigns 10.3

Sovereigns are made by JSB.
Heavies: BC 0.030
Tests from my guns suggest the JSB heavies BC is a little lower than specified but in the 0.025 to 0.030 range depending on gun. I've not tested the Sovereigns.

Re: AA s400 button style trigger

See here https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F332893763040 He made me one with a 4mm hole for my standard MPR trigger. He may be able to make you a special for the rowan. Looks as though the design would permit just drilling out to size if the BSA hole ...

Re: AA s400 button style trigger

Hi, and welcome.
Have you tried phoning Rowan Engineering? They are quite helpful so may be willing to supply one.

Just looked at their website and see they don't list this type. Are you sure it is a Rowan trigger?
Maybe bgaltd (Air Arms Spares) has a HFT500 shoe and will know if it fits.

Re: Firing pot spring tension

I think you need to bear in mind the number of usable shots will depend on the shape of the power curve and how much variation you find acceptable. As you screw the pot in the power will reduce but you can compensate by opening up the adjustment screw on the transfer port. You will reach a point whe...

Re: Shroud

I think you'll find adding a silencer to current models blanks off the shroud so it has no effect whatsoever. I may be wrong for some earlier models which I believe may have attached to the shroud rather than the barrel, a design which was discontinued because they were likely to move and clip the p...

Re: TX200 Hard to Cock

Apart from the force needed are there any other symptoms? Any grinding noises when cocking? Any power loss or change in noise when firing?

The TX200 is so simple to dismantle it's probably best to take the trigger assembly off and check the spring, piston and trigger unit.

Re: Air Arms Magazine Pellet Loading problem.

Yes the magazines I use are air arms as is the pellets. Air Arms don't make a multi mag , only the single 10 shot mags . the muti mags are an after market inject molded / 3D printed product made by someone other than Air Arms . I think most of us took "multi mag" to mean the AA 10-shot mag (as oppo...
