Bob,
Got out this evening and it was a little humid but a great evening to shoot and I even had time to set up the Chrony. Here is what the NULA 280 Ackley Model 28 w/24" barrel did.
140 TTSX Barnes 63.5g N165....... 3100, 3153, 3136, 3119.
140 Nosler BT 60g IMR 4831....... Err, 3154, 3133, 3102
Both loads grouped under .500" @ 100 yards with no signs of pressure. Nosler Brass and Federal 210M primers.
Same range session 7MM Remington Magnum 25" Spencer Barrel
140 TTSX Barnes 71g IMR 7828 .....3235, 3279, 3275, 3289, 3258
Norma Brass and CCI Magnum primers
New lot of powder. Older Tin can container to the new round plastic container. Gave up about 40fps from the last range session and the old lot of powder. No pressure signs. Gonna go up in powder and see where it tells me to stop. Group size was in the 2's.
I don't think there is much more in the 280 but I'm thinking there is in the 7MM. With that being said I think I'll get real friendly with both rifles and see if I can find something to try them out on this fall.
The real thrill for me today was my 14 year old shooting his Tika T3 in .223 off of a Harris Bipod and shooting under an inch @100 all evening.
