  • Just read about a 7mm SAW

    Seems like a cure for something that has not happened , however looks like it also works and is fairly easy to get into, may try it when I finally decide to scrap my ancient shot-out 260 barrel - anyone got any experience / tried it / fad cartridge ? thinking a 7 has a bit more porridge than a 6.5 in terms of weight , however the 150gr's in 6.5 on a 7 twist are mighty appealing to. what do you say (surgeon 591 action / whiskey 3 chassis for fun and games when its windy at 500 to 1000+ yards)

    Insight welcome

      Looks kinda appealing alright.

        I get the ballistics but not the recoil claims.

        Heavy bullets such as the 180 Berger Hybrid and 183gr Sierra Match King can be pushed to around 2725-2750FPS. Those numbers give the cartridge a slight edge in drift and drop over the medium 6.5ís, while still providing low recoil
        How is that "low recoil"?

          So I had read a while back (when going through my wildcat-or-die phase) about 7mm-08 AI. Based on the pictures on the West Texas Ordnance site, it looks fairly close to that. Any idea what differences there may be between the two?

            Looks like the shoulder mainly 6.5cm / 7mm SAW / 7-08

              I'm struggling to believe the velocity claims. That is basically .280 AI speeds with 60-62 grains of powder and 168 class bullets. I'm assuming the saw holds around 45 grains??

                The 7mm SAW is basically an improved 7mm-08. 2750-2775 FPS in a 26" tube is doable in a regular 7mm-08 with an 162 grain bullet, because I've done it. An improved 7mm-08 tops out about 2825-2850 FPS range, with the roomer case yielding about 75 FPS more, at sane pressures. I don't see the SAW sprinklings enough fairy dust to get a 162 grain pill up to 2900, and have any decent case life. IMHO and YMMV.

                I don't see the 7mm SAW being a better match round than the 6.5x47, 260 Rem, 6.5 Creedmoor trio, but a 162 grain bullet at around 2800 FPS would make a mean big game round......Which is a niche it fits into nicely.....

                  I have been thinking about a 708 ai for a while now. I think the appeal to the saw variant is no fire forming. I still think i like the idea of a 708ai better. If it is a hunting rifle the ability to to shoot factory 708 in a pinch is nice and i would think the 708 would have a touch more capacity being that the shoulder is blown forward instead of pushed back.

                    I ended up with a piece or two of what resembles of being 7mm saw after last years Lone Survivor match. A friend sent what he thought was some my 7mm Ackley cases but it's not. In the pic left to right is a 7mm-08 Ackley, middle measures and looks to be the saw case and on the right is a standard 308 palma case which both use. Can't say I see the velocities claimed but I've not seen performance in person.
