Just got back from sighting in my new rig. 7PRC built on a Tikka t3x stainless with a 22" proof barrel and an MDT hnt26 folding chassis. Shoots very well with factory 175 ELDx, the chassis is awesome. I plan to upgrade the optic to something lighter when budget allows but I'm looking forward to September!
I picked up the 300WM tikka used but it was never fired and the proof was a blank I got from a guy who ended up doing a different build and not needing it, so good prices on both. I'm in BC so MDT is more affordable and availabe vs XLR. No suppresors up here so I put a break on and it was very easy to shoot, though loud.
Definitely feeling good about the new setup for elk season compared to the 308 I've used the last couple years. I've killed a 6 point bull the last two years but both shots were close and I didn't love the idea of reaching out with the old set up.
