25-284 Win

Does anyone have any data on this chamber. i have been using data for the 25-06 as to the similar case capacity with caution in mind.

Thanks for the input

    Re: 25-284 Win

    My father just had one finished last year as a switch barrel with a 6.5x284 as his other barrel. Not sure what bullet weight you want to use but I did the work up for my father's rifle with Sierra's 120 gr. HPBT GameKing bullet. I did some very limited testing with Nosler's 110 gr. Accubond since it wasn't shooting very well out of a 257 Rob AI. Here is what I have for both bullets:

    110 gr. Nosler Accubond
    56 gr. N-170, Fed. 210, necked down Lapua 6.5x284 brass
    3199 fps 4-shot avg., 0.498" 3-shot group @ 100 yards

    52 gr. H-4831SC, Fed. 210, necked down Lapua 6.5x284 brass
    3176 fps 4-shot avg., 0.392" 3-shot group @ 100 yards


    120 gr. Sierra HPBT GameKing
    49 gr. H-4831SC, Fed. 210, necked down Lapua 6.5x284 brass
    3001 fps 4-shot avg., 0.352" & 0.453" 3-shot groups @ 100 yards

    I had really good luck with H-4831SC in both the 25x284 and 6.5x284 barrels. Let me know if you want any more details regarding these loads. As always, reduce these loads accordingly as your rifle and components will likely be different. Almost forgot to add that the barrel is 26.5" long.

    Hogdon's have it listed in their #26 manual, so I'd think you should be able to download it off their website

    If you still are looking i own 2 25x284's except the second one is unfired. I bought it used about 5 years ago from a friend who had it built from Ultra lite arms 5 3/4 lb. gun. He already had the data but i shoot the sieera 100 grain spitzer fb with 58 grains of Imr 4831. Yes it is close to being hot but i get close to 3500 fps with it. Very good chambering its close to a 257 whby but with a short action. If you try other bullets such as the 100 nosler bt back off from this load more bearing surface you will get pressure.
