7mm-08 Ack Imp Throater q? 2 1/2 degree

I want to build and shoot a 7mm-08 ackley improved to shoot the 162 A Max's_____

I need some advice as to FREEBORE, LOADS and BARREL TWIST recommendations for a 28"+- length barrel in a 700 SA. I am considering a 1-10", and have seen a FB recommendation of .175" for the VLD's...but I want to shoot the A-max or maybe a 168MK

I am looking at shooting it in F-Open at 600 and 1000yds due to its .625BC

thanks in advance
 
I ordered a 7mm throater from Brownell's and then I relaized it is a 2 1/2 degree_________ a friend told me that I nedd a 3 degree reamer and to send this one back. I plan on shooting 162 A-max and Sierra 168's will this 2 1/2 degree work or am I better off with a 3 degree throater?
Thanks,
 
Most of the reamers we have at the shop are 1.5 degree. Max of 2 degrees though. At least one reamer is a .75 degree.
 
BHarvey___ you have in stock. What company?

This is what I ordered for Brownells____Is this a bad one to use for my purpose? I am also thinking about building a M98 for hunting with 140 grainers....

This says 2 1/2 degrees, which I would think is the total degree___If I understand this application you are saying 1.5 which is a total of 3DEGREES___

Clymer
SPECS: THROATERS - 5, left-hand, spiral flutes. .002" larger than bullet diameter. 2½° throat angle. Used to lengthen throat to increase freebore. ¼" diameter round shank.

Thanks in advance:D
