    Why?

    If you want .260 velocities, the best way to do it is buy a .260!

      Why not? Besides the 260 won't fit in an AR-15 platform.

        What does QL say about 100gr Sierria and the 110gr Barnes? curious?
        100gr @ 3000 = Possiable member of the broken bolt society.
        As Bwaites pointed out yep if I need that speed per se git a .260 but I do find the data interesting and wonder if QL picks up the pressure differance in the projectiles?

          I am going for 2950-3000 with my 85 grn. gmx & IMR 8208. I'll be working that load up in two weeks from now when I head to my hunting zone. As far as 3000 with a 100 gr. pill,,,, is it worth the possible damage? I could see 2900 with the 8208 powder. I used to shoot a 7 rem. mag with light bullets-130-140's and had speeds of 3150-3250, I called it my lightning bolt. And my shoulder bruiser! This new load I'm developing will replace ( with less blast and overdamage) the old 7mag., in terms of speed and close in effectiveness. Bill, another option I looked at before getting the Grr. bug was a Dtech 6.5 wssm. Same speeds as a .260 in a single stack mag. AR. Dtech is here in Bemidji Mn. I'm sticking with my setup.

                All the luck in te world to you guys. Keep us posted please. For hunting, it is my understanding that an IMPACT velocity of > 2800 fps is what is required for those catostrophic 1 shot kills. So maybe... trying to find a bullet/powder combination that hits a critter @250 yards at >2800 fps would also be a worthwhile goal

                  mseric ya da man thanks for running that, humm nearly 4k psi more for the sierria I wonder if the barnes 110 Solid with the reduce bearing surface would result in less pressure closer to the 50K limit for the AR Platform.

                  Just checked what I load my COAL to is 2.210 vs 2.250 on the seirria

                    Since the Barnes is harder, it fights being driven into the lands more than conventional soft copper jackets. Could mean similar pressures... It is possible to run the lighter bullets pretty fast out of a 24" or longer pipe. You still aren't gaining much in effective range though, since the bullets lose a lot of gas around 500 yards. The difference between 3000fps MV and 2900fps MV with a 107 SMK only means a change of the 800 foot-pound shift from about 530 yards, to 570 yards. At 1000 yards, you're only between 330 ft-pounds, and 350 foot-pounds.

                    For those of us that shoot steel at the further distances so you actually get target feedback, we like to hear some umph when the projectile impacts the steel. For that weight class of projectiles, you need to drop down to the 6mm to keep the gas running for 1000yds. If the goal is a faster flight time to 600yds, the 100gr-class projectiles are pretty awesome in 6.5mm. You have about 1.5-1.6 MILs in wind drift for full-value 10mph wind speeds at 600 yards with those velocities and the 107 SMK.

                      The tought of harder alloy did not occour to me, which would change the friction and the resulting pressure. Moly coating them would reduce the Velocity. Funny how this leads to thoughts of wringing every fps outta a cartridge. Ohh well think I will attempt to work out the bests load for accuracy for the Sierria @ 200 yds for now.
                      Just loaded some 100gainers over 30.5gr of TAC , with a C.O.A.L of 2.210" in LBC brass with WSR primers wish me luck.

                        Lrrp. 52, and sgt murf : aka; (the speller) hee-hee , - The alloy is way diff. from a barny- to a hornady-gmx. Barney- is not my fav. anymore.

                          Alrite muurf, I gott eeett. = let it slide, down the bbl. at slower velocities, until; u change eet upp- do eet now!!!!!!!!!!!!!! No time to talk. Make id happin. Get going, alloy up, skip all the lead core based units, time to move forward-start a new- lead - free !! All the states are going this way- next few years. It will show up when you least expect it. Trying to help- is all I'm doing. It's not worth the ??? to chase, (or is it?) the 3k barrier with a 100, instead of a 95 gr. hmmmmmm..... I'll find out soon enuff- in 12 days I will be at da range.

                              I am aghast!!!

                              We should never use quickload without having first compared it with actual pressure data. There's a enough available to check your settings.

                              Can you post some real data compared with your calculations?

                              Even then, remember the max pressure is 50,000 psi regardless of whether you've used higher pressures with no apparent ill effect.

                              The harder you hit the bolt, the sooner it will come apart.
