Morning all,

I have recently got 2 new rifles - a Goldstar and an Ultra se, both .177. These are the first BSA PCPs that I've owned so, my knowledge is very limited. I've put about 30 pellets through each one so far.

I'm happy with them but, I do have a couple of questions.....

When I fill the Ultra, I hear a 'ping' sound (maybe the valve opening?) and as the pressure increases the rifle starts to sing/whistle. I always fill as slow as possible. I can make the singing stop by shutting the dive bottle valve for a couple of seconds before starting again. Is this normal?

Also, is the power likely to creep on either of these rifles as they 'bed in' as it can on others?

I'll be putting them both through my chrono as soon as my new batteries arrive but, any advice from experienced users is always appreciated.

Thanks for looking.
