    I am entertaining the idea of 7mm on a LONG ACTION. What are your opinions on the .280 Rem (not AI, yet)? I am inquiring about the 168 or possibly the 180 grainers. I have already completed a 6.5 X 284 shooting the 140 and 142's....and a .243 shooting the 105 and 107's, so I was trying to "fill the niche" in a Wanting the velocities in the 2800+ range also. Is this feasible, possible, etc? My intent is clay birds/steel and occasionally deer sized game. Thoughts please............I guess I should ask about some load data and possible builds that are completed and performance of them. Thanks

    How long of a barrel? My 24" .280 will put 160s over 2800, but I haven't shot anything heavier. My current load is 54.3 gr IMR 4350 under a 140 Accubond. Surprisingly, it is only going 2850 fps (other lots of this powder have driven this same bullet over 3000 fps), but I don't have any problem with it out to 600 yards. It drifts a little less than my service rifle with 82 gr Bergers. 5 MOA for a 10 mph full value wind. a 168 Berger at 2800 only drifts 3.5 MOA. Perhaps I may have to play with some. :)

    By the way, I am building a long action 7 WSM for a long range deer rifle.

    I will probably start with a Krieger at 30-31" and hope to finish it at at least 28". I was "hoping" to get the 175''s or 180's to shoot primarily because of the B.C. THe 168's have a good B.C. also. I was thinking at least a 9 twist and was looking advice on IF I should seek a faster twist. That IS a nice rifle you built and if you don't mind me asking, what did Leupold charge for the turrent upgrade and reticle change?

    I just paid $189.98 to have M1 turrets and a standard duplex reticle installed in a 6.5-20x50 LRT. It is really nice.

    If you want to shoot the 175-180grain bullets, move up to the 7wsm or bigger. 280Rem will have a hard time pushing them at 2800+. 1:9 twist will work for everything from the 140's to the 180grain bullets.

    Turrets were eighty or ninety dollars each and the reticle was ~$160.

    My 280 is shooting the 168 bergers at 2940 with 57gr of imr 7828ssc seated in the lands 15 thou out of a 26" mcgowen barrel. This is 2 grains over bergers max but is not showing any signs of pressure in my rifle. i have shot the 180's but only about 2750 befor getting pressure signs.
