I am shooting 56g of IMR 7828 in formed PMC 30/06 brass, and the Federal 210 primer sucked the bullets in a ragged hole using 175g Nosler Long range accubond. I have not checked the speed.
The 175's were darn easy to tune, and I seated them just off the lands, can not remember how far, but they were very close, .003-.010. The Federal primers shocked me in how small the groups were compared to Win, 215's, and CCI 200 & 250.
I have heard that the 168g LRAB are very, very accurate seated close to the lands, also.
I also formed brass from Lapua '06 brass, shot the same load. 14.6g of bullseye, cream of wheat, tuft of blue paper towel, gives you a 97% formed case. Clean the barrel every 25 rounds and cool the barrel. Check the inside of the shoulder with a bent paper clip for Cream of wheat that stays in the case.
When using '06 brass, the neck will be short. and carbon will accumulate in the neck. So, use a bronze bristle pistol brush with a tad bit of your favorite solvent on it, and give the brush about half a dozen spins by hand in the neck. All the carbon will be gone.
The 150g LRAB were a POS to tune, gave all I had to my brother. The 175's LRAB just shot well, right out of the gate.
Concerning the Nosler long range accubonds, sort them by ogive length. The lengths do not vary much, but you will find a bug hole load within a certain distance from the lands, maintain that bullet jump.
Concerning the std 280 Rem, in the Nosler manual #4 there is a load with IMR 7828 with Fed primers, shooting the 160g bullet at 2930 fps in a 24" barrel.
In the Rem 700's I have had over the years, the load data above is spot on.

Two three shot groups-cool barrel inbetween
When I changed out to IMR 7828 with the 175g LRAB, FORMED Lapua brass, all bullets touched in a group that measured in the 3's. My rifle is a 27", #5 taper, Rem 700 in a laminated stock.
