Forbes are good...:)
If you haven't already, buy Nosler's manual. They have a lab...and they actually shoot the cartridge...:)
The Nosler loads I have shot in a RI 280AI (SAAMI) are right on the money--I subtract 50fps for their 26" barrel data in my 24" Ackleys. The RL 19 load is matched with a grain less. My guess is the snug chamber. The ULA I had back some time ago also had a snug chamber. There wasn't manual then per se, but it would not digest loads that had gone thru two other AIs that I had.
Not trying to draw a parallel betwixt Melvin's rifles, but assuming it is probably made just as well and any rifle can be different in regard to the same load.
The Nosler manual loads worked up with a chronograph, give better guidance than any one else loads, experience or opinion.
fwiw...
added: powder-wise, mine have done well with stuff on the slower side. currently runnning MRP, but not married to it. RL 23 looks interesting...
