    Anyone with experiance with this Cartridge? It on my list as a long range Deer and Elk Rifle.....................My next and last ........

    What barrel length? Contour ? I would use the 168gr Berger VLD Im leaning towards the Cooper Jackson Hunter, for my pocket book thats a heck of a deal for what others have said about the coopers

    Mid process of build right now.

    FN Mauser 98 action
    Kreiger #3 sporter .284 1:9
    .280 Ackley Improved chambered with PT&G bushing type reamer (the real deal, not the SAAMI Nosler/Rem spec'd cartridge that is .014" shorter than the original)
    Timney Featherweight
    Tubbs Speedloc
    Cerakote
    B&C Medalist Varmint stock in green w/black spiderweb


    Just finished up the barrelled action yesterday. Gonna start bedding it in the stock as soon as I have some more time off. Planning on Redding Full Length bushing dies and Norma fireformed brass, but haven't quite got that far yet.

    FN Mauser 98 action (an antique by mosts standards but a good action and the best 98 Mauser IMHO)

    Kreiger #3 sporter .284 1:9 (premium barrel maker, #3 sporter describes the contour or outside dimentions, caliber .284, twist 1:9 I chose this twist cuz I plan on shooting heavy for claiber bullets)

    .280 Ackley Improved chambered with PT&G bushing type reamer (the real deal, not the SAAMI Nosler/Rem spec'd cartridge that is .014" shorter than the original) The original .280 Ackley Improved and the .280 AI as spec'd by Nosler when the cartridge was standardized by SAAMI is .014" shorter than the original P.O. Ackley cartridge. Why, I don't know, but .014 is that much more powder I can squeeze in there.

    Timney Featherweight (aftermarket adjustable trigger)

    Tubbs Speedloc (aftermarket firing pin and spring combo that decreases lock time or the time between when the trigger breaks and when the round is detonated)

    Cerakote (a ceramic bake on finish that is corosion and abrasion resistant)

    B&C Medalist Varmint stock in green w/black spiderweb (aftermarket carbon fiber stock with integral aluminum bedding block)

    I am not a gunsmith but I do as much for myself as I'm capable of. I had a smith do the machine work on the barrel-threading, crowning, and headspace. I installed the trigger, firing pin/spring, and wiht help from a friend applied the cerakote.

    I shot my cousins 280 ackley and it impressed me so much I have one being built rite now:

    Remmy 700 action (Blueprinted) with old style trigger
    Shilen #6 contour 1 in 9 twist
    Boyds Featherweight laminated thumbhole

    140 grain Berger VLDs over RL 22
    Leupold VXIII 4.5-14x40 or 6.5-20x40 havent made up my mind yet on the scope just depends on my wallet at the time my smith calls and says shes ready.

    Sako 75,left hand, mcmillan sako hunter stock, benchmark #5 contoured 25" barrel 1-9 twist, zeiss 4.5-14x44 mildot.
    I shoot the 168 berger at mag length as follows:
    168gr berger hunting vld
    54.8gr rl 17
    nosler 280ai brass
    Cci br primers
    Getting 2870 fps. Shoots 2/3 -1/2 moa.
    I like it but if I were to do this all over again I would get a 7 saum or a 7 wsm. You jusy have to push the 280ai hard to get the better velocities. 7saum is more efficient and if you use a long action you can have your bullets seated wherever you want!

    Yes he did! "Montana gunsmith Dan Cooper (founder and part owner of Cooper Firearms,) has been ousted as chief executive of the rifle company that bears his name after pressure from gun owners who are angry that he is supporting Democrat Barack Obama.

    That was true .................The CEO for Cooper was an Obama supporter. Story goes that he did not want Hillary in so he gave $$$ to obama. He was fired by the board so he is not there..


    Cooper is a great rifle and hard to beat the price for all you get.

    Ive got one based on GAP Templar action. With 168vld and 55g560 it is a 1/4 MOA gun. MV is only 2700fps but neck tension is low and it has plenty of killing power out to 600.

    I think they are the best with 140-160 bullets. A wsm on a long action would be hard to beat. 280ai wins on coolness though ;)

    Greg you are correct! You could also build a rifle that would be close to that in price minus the fancy wood stock. Many ways to build rifles on a budget.

    I have a Rifle Project at Carloina Prcision right now. I sent in a Remington 700 action and a McMillian Remington Sporter that I had ordered for the project. This is my first custom rifle. Im having a Pac Nor Super Match installled for the .243 Ackley. 24" #4 1x9. Its also getting a Sako Extractor as I was told that that would be a good idea, plus Its getting a Jewell Trigger. Matt Poly Kote ...................$$ 1850 Pretty much the same price I would have paid for a Cooper without the six month wait.....................However Pac Nor like so many other barrel companys are way back ordered and what was suppose to be 12 weeks is now 20
    I talked with John Lewis last week about getting a barrel make for it in the 7mm-08 Ackley...................I know that one day soon Im going to wish I had something a little bit bigger as my wifes parents live in Carmen, Idaho right on the Montana, Idaho boarder. They ask me if Im coming up to hunt Elk this year ....................??? I dont have my rifle back yet and if I do ...........I will buy a deer tag..................instead

    That's why I have an interest in the .280 Ackley Im sure that the 7mm-08 Ackley will do the job.......................But then I would like to have a Cooper just to see if they are everything people say they are.
