I have a SPR barreled action in 300 Win. Mag. on a Bighorn SR3 long action with the Wyatt's extended cut. Do any of you know if the action will work with AICS magazines in a chassis? Yeah, I know I can call Bighorn on Monday, but I am looking at a killer Black Friday deal on a chassis and there is a very limited supply. It would suck to buy the chassis and find out it will not work. It will also suck to miss the $300.00 discount. Thanks in advance.
