I had the same rifle what I found with the short barrel N560,RL22 and other slow burning powder that shows good speed in reloading books are lucky to get 2500 fps with a 140g bullet, I changed to RL17 ,RS60 and found good accuracy and 2700 fps,
Hi
I also find the .223 excellent for vermin control, I find the 77g TMK a good bullet and have taken rabbits out to 400y, recently changed to the oryx chassis can't fault it. One on top of two what powder do you use, I am getting 2920fps with cfe223
I had the Tier One tactical bipod, and returned it as when attached to rifle the barrel would touch the legs of bipod when canting this will depend on the thickness of the forend on your stock as it sits between legs, I changed to a atlas CAL and find it a great bipod to shoot from.
How do yous find the adjustable cheek piece, with a two guides that hold it close together is it wobble free,the under side of the buttstock looks to be sloped rather than parallel to the barrel how do yous find it tracking on a rear bag.
