Bad part about trying to find a Remington take off HS stock is going to be the barrel channel size. Most (if not all) are going to have a Varmint barrel channel, which will swallow your sporter barrel whole.
When you say the 270 is a shooter, what kind of groups are you getting out of it? The Hogue should be pillar bedded and a little bedding around the recoil lug will go a long ways on helping any accuracy issues you think you might be having.
Before I spent $250 on a new stock, I'd spend $25 on some JB Weld and sand paper and bed the recoil lug and make sure my barrel is fully floated. Just my opinion though...
