Regarding the take down, I applied some Kroil, hoping it might help break the bond while shooting it...
...which I did today for the first time. With fear and trepidation I sat at the bench and pulled the trigger. What a pussycat!

Well, what I didn't tell you is that I loaded 10 cartridges from mild to medium in order to break me in. All with Hornady's 300gr HP and Reloder 7, I started with a couple 45gr loads, working up to 52gr. I then shot 5 rounds of Hornady's factory FTX loads, and those weren't that bad either.
Amazingly, my first shot was on the X with the next 4-5 within 1". This incredible feat was accomplished at a distance of 25yds.

As the loads got heavier, they moved a bit down and to the left.
Very happy with this rifle. Had heard horror stories about the recoil from this cartridge (and 45/70), but it was nowhere close to some my heavy loads in 12ga. Closer to a heavy .30-06 load in my Model 70, actually. Maybe it's because the gun fits me so well.
Loaded some more 300 grainers over 52gr of Reloder 7, plus set up a dummy round with Hornady's 350 gr Interlock for next loading session and range trip.
