I need the help of you 6x45 shooters.  I have decided that I need a 6x45 BHW barrel to build an upper for my AR to be a companion for my .243 and 6mm Remington bolt guns.

 

I plan on getting a 20" standard profile barrel and shooting 80-90 grain bullets for hunting deer and pigs. 

 

My question is which twist rate should I choose? 1 in 9 or 1 in 10?

 

Any opinions would be appreciated.

 

-Bob

I would go with the 1 in 9.  It will stabilize the heavier bullets you may want to try later. I am talking up to 100 grains. It also works well on the light weight bullets. It's a win win.

I just ordered my 20" barrel. I am going to mate it to an American Spirit Arms side-charging upper.  I see a lot of dead pigs in this barrel's future.

Post up pics as it goes.

YES!!! My barrel should arrive by Tuesday. 

 

I have the upper receiver, bolt, and the piston system.  All I need is the hand guard and the flash hider crush washer and I am ready to get her assembled.

 

I also have 150 cases sized, trimmed, and primed, several pounds of XBR 8208 and several hundred 85 and 90 gr Sierras and Speers.  Good times are coming.

Thanks for the info. I'm getting ready to order my barrel and it has been really informative.
