Your ammo and brass plan look about what I did a few months ago.
I sold one gun and they offered me a killer deal on a #1V in the rack, 220 Swift. I would not have took the bait, but I knew the gent that it belonged to, he shot maybe 40 rounds through it.
I have read on the Swift for years. I think there maybe a lot of misguided information out there, much like other high velocity varmint cartridges, 17 Remington being a main one as well.
I disproved a lot of old information on the 17 Remington, so it was only natural to give the Swift a shot.
I refreshed my memory on the #1 and once again there were some issues said to be possible with this combo. I had a scope mounted and a box of the Nosler ammo in hand, off to the range. Three shots and I had my elevation and windage where I wanted it.
While letting it cool the 17 Remington was given its chance @200. I pieced this rig together a few years ago and have not regretted it. First shot was 1” high of my known zero. The next four stayed under 1 1/2”.
The Swift had cooled and I left it dirty. I ran three @100 and was more than pleased. The next two I went to 200 and was pleasantly surprised as well.
If I can get my hand loads to match the factory Nosler, I will be pleased.
Doubt this will be used much except for stubborn prairie dogs at a distance. Can’t bring myself to thread it for my surpressor, seems almost sacrilegious.
