With the Swift 53 grains might be pretty hot. With 130 Bergers I was getting flat primers at 52.5 in hot weather. Dropped back to 51 grains and still getting 2950+/- fps.
Berger tops out at 50.6 for the 135 elite.
I agree with that. My current lot of 26 is pretty quick. As always, work up from low until you know where you’re at with the data.
