Tikka 300 WSM 180 grain Swift Scirroco II load development with H4350 and Rem 9 1/2M

As a previous 300 WSM load development video I had made for 180 grain Barnes TTSX I had issues stabilizing them in my 1:11" twist barrel.

I made a ladder test and found a 5 shot group wiht an SD of 10 and ES of 20, fair numbers for long range hunting. However grouping was at 2" and I would like to later fine tune this load by performing a seating depth test.
