Actually it does, when a 280 with a 26" barrel is doing well to get 2950-3000.

Even a couple of Tikka Rem mags I have played with don't really like going 3050

As I have mentioned it isn't your typical 708.....

It has a 34" fast barrel & an extremely strong target action.

Yes, and if you run a 280 with a 34" barrel the velocity will be very high to. All I'm saying is that a 280 is a much bigger case and does make significantly more velocity than a 7-08. Otherwise we would all be running around with 7-08 long range guns.

I must have read your reply to LJP wrong.....or not ???

Like Kiwi Greg my 7mm08 thought it was a 280 Rem - 24" barrel & long throat so the boatail junctionof a 180gr VLD was above donut gave 2,600fps & the 162gr Amax up to 2,850 fps. Scary performance for the little 7mm08.

Your reply

That's at least 200fps off a 280. So not really comparable.

I thought the thread was about Velocity gains with longer throat as such LJP post has more relevence than mine as he has a more normal barrel length.

I went 708 to get the speed without the powder to keep the heat down & barrel life up for LR steel shooting.

I have out grown the little calibres & prefer to play with the bigger ones now, well out past 1000 when I get the opportunity.

I had thought about running my 280ai reamer in long as well as long throating it for a giggle :)
