Theoben Rapid more accurate when single loaded?

[Ka-Boom!]

I took my magazine apart tonight and reduced the spring tension one full turn (there's basically no preload on the spring at all now), guess what.. it's worked! The pellets don't get crushed now and accuracy is spot on .
Thanks.

You need a bit of preload, or the mag won't index, but I get your point.
I have unwound mine as far as they'll go, and I still get slightly deformed skirts when using soft pellets.
Maybe it doesn't matter, and is not effecting the accuracy, but I'm striving to get the best out of BTAS / AWT Mk2. I've managed to get a couple of 100 yard 1MOA groups when single loaded in perfect conditions, and I just don't think it'll do that with the mags.
Incidentally, it's got a BSA 19.5" choked barrel and I'm having that recrowned today by Dasherman to see if that helps?
