280 Ackley vs 7mm Rem.

I was wondering if a 26" 280 ackley will have a velocity about the same as a 26" 7mm remington magnum? Can I get the pretty close the same velocity out of 168 and 180 grain bergers for long distance? or should I go with the staight 7 mag?

Dave.

The 7 rem mag has a 8 to 10gr advantage in powder capacity over The 280 Ackley.

For 160gr and down the ackley is very close in velocity. But with heaver bullets the
7 RM has the edge.

So depending on whitch bullet you want to use this should help.

Both cartriges are very good performers so get what you like the best.

Re: 280 Ackley vs 7mm Rem.

I prefer the 280 AI, as you get close to the same velocities as the 7mm rem but with much less recoil and better barrel life. Also it is my opinion that the 280 AI is MUCH less finicky than the 7mm rem. Better accuracy potential, better life, less recoil more than makes up for a few FPS the 7mm rem may offer.

Re: 280 Ackley vs 7mm Rem.

Thanks guys for the reply, I was just thinking about getting a 280 ackley built as soon as I found a donor action. I am glad to see that I can get very close velocities from the Ackley compared to the 7mm mag.

Another quick question, I was thinking about going with a #5 contour barrel, in comparison would the barrel be about the same thickness of say a Sendero barrel? I believe specs on the barrel say .750 at the muzzle. I was just wondering if I built it with that barrel would it be too heavy to carry around? and what twist should I go with to shoot all ranges of bullets up to the 168 gr bergers.

1:9

#4 contour is getting pretty heavy unless its fluted, maybe that would help. Maybe a synthetic stock would help with weight too, but it might throw off the balance.

my 7wsm is a 26" #5 pacnor supermatch, paired with a winchester classic laminate stock. It's pretty heavy to me. Definitely an open country gun not a mountain gun.

Re: 280 Ackley vs 7mm Rem.

The rifle will be in a h-s precision stock, fluted barrel, I am guesing maybe now a #4 contour, I wanted to build a 8 to 9 lb gun with scope? Would the #4 contour still be too heavy? I stilll want a pretty ridged rifle, and a not overly shin barrel, just a little heavier than factory contour.
