280 AI Results with 175-180g bullets

VinceMule · Jan 4, 2024

Would you mind sharing your loads?

I worked up a load in my 25", with 57g of IMR 7828, federal 210 that shoots tiny groups but have not checked the speed. It would be nice to hear how others have fared with this bullet weight.

I sort by ogive length, seat to within .003 of the lands in my chamber.

Thanks in advance

STABALL 6.5 AT 55.5 GRS, CCI BR2 primer, Hornady 160gr CX running at 2900 in 22 inch barrel. Great accuracy and results on antelope and deer this year. I mention this 160 gr as Hornady said it wouldn't stabilize in a 280AI and was for larger 284 calibers but works great. Thought I would just throw that in there even though not up with the 175 gr for another option.

I am beginning to believe the 280 Ackley is the 6.5 Creedmoor/308 Winchester of the long action. I am constantly surprised by sheer number of different powders that are usable in the 280 Ackley.

I use about 64gr of Retumbo with a 175 EH, mag primers, and Peterson brass to get a little over 3k with mine, which has a 26" barrel.

This literally blows my mind in a 280AI. I haven't tried Retumbo or the 175EH, but I'm wondering how you got 64gr of powder in the case with a 175.

Mind me asking what primer you are running with the Retumbo? Great! Thanks for sharing!

Nosler brass CA ridgeline 175 EH
Retumbo 62 gr got me 2911
N560 60.6 gr got 2917 fps
Retumbo load at 60, 61, 62 gr of retumbo were all touching so that was my first real trial handload after breaking in. Might have just hot the easy button. Not sure i need to push for more than 2911 fps with a 175gr. Bolt lift was easy on all.
