That's the plan! Sidesteps the hassle of a rimfire and might even have a competitive edge on account of the lack of recoil.
I think balance is a very personal thing - I definitely prefer a lot of mass at the front and can shoot noticeably better with such guns. I can't hit sod all with my TDR from a standing position
I will be looking to stay inside the NSRA rules; at 3.3kg I think the full-size rifle will leave plenty of room inside the regs for optics and I don't use a glove - although I suspect I could probably sneak one of those it too as they can't weigh too much
