Has anyone pushed the 178 Amax from there 300 win mags? If so what were your results I have 800 at home I bought for my AI but we it being a 12 twist I'm unsure the 308 will stabilize them.

A 1:12 WILL stabilize them. But I had really good luck with IMR 4350. It's been so long ago that I can't remember the charge weight. I'm headed to the camp in a bit. I think I've got all the old data there. I will post back if I find it
Btw... That's for the .300 win mag
With Imr 4350, something around 70-72gns should be about right for about 3100fps from a 26"bbl
I should made my first post more clear, my AI is chambered in a 308, originally the 178 amax was bought for that rifle but the stability factor looks to be marginal. So I figured I'd give them a try in my 300 WM and see how well they shoot from it.

I tried them in my 300wm, they were great with 4831sc. However I thought I should be shooting something larger, so moved to the 208-210 range.
Got a 300wsm and the 178 is all I shoot in it. It really likes them.
Both my 300wm and 300wsm are 1 in 10, but I would not worry about the 1 in 12.
Good luck.

300WM with 72.0gr IMR4831 shot pretty well for me.
I need to go get some IMR powders I have H4350 and H4831 but nothing in IMR except 4064 for the 308
I'm gonna test the 178 in the 300 and 308

The H powders will work just fine and I prefer them as they are more temp insensitive. Just look on Hodgdon's reloading portion on their site for data for the H powders but they all have IMR and Winchester powder data as well.
I found my load for my old 700 Police with the 178 amax. It was 70.0 IMR 4350. 3.590" coal, 3100 fps. If I remember correctly it was a tad on the hotter side so just giving you a heads up. Btw... Winchester brass
My load was with 180gn Sierra GK's and 71.0 of Imr 4350. The SGk has a smaller bearing surface, if I recall, and thus can run a slightly larger charge. Ymmv
Thanks guys I'm gonna try H4831 and 4350 with those 178's
