162 gr A-Max twist tate

[zeus]

What twist rate is being used stabilize 162 gr -max in 7mm.I'm putting a 280 Rem together and undecided what twist rate to order.

Hornady recommends 1 in 8 twist on their website but I have been told that they should stabilize fine in the Remington 1 in 9.25 twist. I will find out as soon as I can get to the range with my 7RUM. Berger recommends 10 twist for their 168 gr VLD and 9 twist for the 180 gr VLD. Hope this helps.

I shoot them in a 1 in 11 twist 7 mm RUM at 3200 to 3300 fps with no problems.

The 168 SMK and Bergers keyhole at 100 yds for me, but 162 AMAX are fine ...

I was wondering why Hornady prints 1 in 8 twist on the 162 AMAX boxes myself.

I didn't make a very good choice in twist rates as now I am limited to 160 grain and lower bullets.

(I understand it is bullet length not weight that determines twist required.)

I´ve shot them ( moly) in a factory rem with a 1/9 1/2 twist , 7 rm, with good results.

I've shot them also in a factory 7mmRM, 1-9.5" twist @ 2950fps and they were fine to 500 yds which was the furthest I've shot with that rifle.
I've shot them at 1000yds with a 7 WSM and a 1-9" twist @ 3000fps, .5-.75 moa no problem for 5 shots.

My 1 in 10 twist 7 RM stabilizes them fine.
When I build my 1000 LG I talked to Joe Thielen an engineer at Hornady who shoots the 162gr A-max in a 280HK 1000yd LG and he said a 1 in 9 twist was best. In fact what he said was I wouldn't even consider going with a 9 1/2 twist.

I have shot them quite a bit from my 7STW with a Hart 10" twist. Accuracy is excellent.

According to Berger, a 10" twist will also stabilize their 168VLD but not the 180VLD.
