+p spring help.

[mjkortan]

Hey guys anyone have any experience shooting +p out of the vbobs. I got a great deal on 1000 rounds of ranger t 230gr +p and am looking to up grade recoil springs. Do you think a 20lbs will be to much and will I need to switch back to the stock spring when I switch back to a standard load. If you could provide a link for springs that would be great because apparently I'm a little slow today and can't seem to find any.
