I had really good success with a Ruger and SAvage
Using AA2700 with the 50g Ballistic tip, fed 210, bullet seated to touch the lands. These two rifles shot bug holes at 100 yards at an honest 4000 fps.
While IMR 4064 is probably the old stand by for the Swift, it sure is rough on barrels in this caliber compared to the AA 2700.
My load with these two rifles was 44.0 & 44.5g of AA 2700 with the 50g Nosler. Due to the engraving pressures generated by the Barnes bullet, I would back off a full 5.0g and work up from there jumping the bullet .030-.050 to get the most accurate load, then play with the seating depth.
I will watch for your success with this cartridge and bullet as I am sure will many other people.
