I did a search of the reloading forum and was surprised that there was no data for the 280AI. I am needing a starting load recommendation for the following bullet weights. Going to head to the reloading store later and need to pick up some powder and primers so what powder would you guys recommend?

Nosler BT 120Gr using Moly
Nosler BT 140Gr using Moly

I also have some Barnes TSX 120Gr and 140Gr coming to try also.

thanks

'22

And 200's.

1) Kiss
2) Find pressure
3) Rock on............

Nosler has very good data. Check their website.


Without moly in a 9 twist, 24" custom barrel:

120 V-Max (TSX very close)
Best load was 61.0 H4350 Extreme for 3370 fps, 62.0 gave 3430 fps but a bit hot.
Ramshot Hunter, 63.0 = 3360, 64.0 = 3450 a bit hot. Ramshot needs a magnum primer.
RL15 was good but not as good as R. Hunter.

140 TSX
RL22, 61.0 = 3110, 62.0 = 3190
H4831 Extreme, final load 63.5 (slow lot) for 3160 fps and better accuracy than RL22

150 TSX and 62.0 H4831 Extreme = 3050 and amazing accuracy, my keeper load
