My STW and the 162 A-MAX

Loaded the A-MAX with 80gr H1000 Fed 215M primer's.C.O.L at 3.700.Ten shot velocity is 3113.Shot 3 3 shot group's.The first one had two in the same hole and one about a bullet dia higher.The other two were not so good.But were still under an inch.The gun kick's HARD.....Need's a brake..Got my eye on a big coyote.And I think this gun will do the trick....Using the Leupold Long Range base with Burris ring's.+.20 in the rear and -.10's in the front I used only 1 click from bottom for my 100 yard zero

Re: My STW and the 162 A-MAX

Boyd,
I was very much interested in trying the A-Max in my 7STW but after buying a box I was told by Hornady that they would not be stable beyond 100yds if used in my 10" twist Hart barrel.
Oddly enough, that is the same barrel and bullet that is used in their newest reloading manual.
So far I have had exceptional accuracy with 140gr bullets.
What twist barrel are you using?

It's 27" with a 9 twist.I am going tommorrow to shoot it at 700 1000 and 1250 yard's to make any final adjustment's to my drop chart.Will let you know how thing's work out.

Re: My STW and the 162 A-MAX

In the mid 70s Hornady made a 162 Rebated B.T. Match Bullet for the 7mm. I used 75 gr H4831 in a 7mm/300 Wby and it shot real good at 1000 yds. When they quit making the rebated boattails I tried the new ones but they never shot as well. I tried the new 162 AMAX bullets at 100 yds and they were very impressive with the same load. Velocity is 3300 fps out of my 30", 9" twist Hart barrel. I've yet to try them at 1000 yds, but probably will this year, but the 168 Sierra Matchking shoots great with 1 grain less powder.

The above velocity was mistyped it was 3200 fps NOT 3300. Sorry (I wish it was the latter)

Re: My STW and the 162 A-MAX

The test's on my STW today looked very good.Shot it at 700 900 and 1200 yard's.My 1000 yard and 1250 yard rock's are quite big so I found small one's at 900 and 1200 yard's.The 700 yard and 900 yard test's were a perfect five for five on both rock's.At 1200 yard's I missed the first shot a little high and had about 8 inches of left to right drift.After some adjustment's the second shot was right on.The gun won't be used out past 7 or 800 yard's but it is good to know it will hit something out that far.The guy I had with me had never shot at anything past about 100 yard's.And he could not believe that he could hit something at 1200 yard's or 700 yard's for that matter.He want's to take his brother the next time.Said his brother would never believe it.Anyway we'll see if it can hit a coyote at 1000 yard's or so.

Re: My STW and the 162 A-MAX

I have a factory sendero in 7STW. What would be the twist rate?
