Federal MSR Fusion Now In 6.5 Grendel and .300 Blk

Federal just announced they will be offering their Fusion MSR line of ammo in 6.5 Grendel and .300 Blk.

Their 6.5 Grendel will come in a 120 gr bullet and their .300blk will be a 150 gr bullet. The Grendel ammo will cost $29.95 and the blackout will be $25.95 a box.

  • I just wish they would release their 62gr Fusion in a 5.56 pressure loading.

    The MSR is rated for 2750fps; a 5.56 62gr would be clocking 3,000fps.

      Give it time.

      Since it’s marketed as hunting ammo, they may not want to produce a 5.56 loading out of fear of users using in a .223 chamber.

      • I can understand offering the Fusion in .223. But the Fusion MSR is supposed to be designed for “MSR’s” aka assault rifles. You would think that would be a 5.56 chamber.

        What’s maddening is that Speer only offers their Gold Dots in .223 – and loads them to 2650-2700fps. And that’s for dedicated LEO / self defense ammo, often out of SBR’s that really need 5.56 pressure.

          It is frustrating, but from what I can find, the Speer Gold dot 64gr is loaded to around 2780FPS. the 75gr is also loaded to about 2700FPS (20″ barrel). So the 75gr is actually a fair bit stouter than the 64 grain loading. Which is disappointing as the 64gr is the most accurate out of my AR-15, a little less than MOA on 5 shot groups, the 75gr is a little over MOA. I am planning to use the 75gr for deer this fall (my state requires a minimum energy, not a certain caliber, for deer and I am sure they’d just accept the crud printed on the box, but out of an actual barrel, the 64gr doesn’t hut the minimum energy requirements, the 75gr does, barely).

          I actually learned that Speer makes 168gr .308 loadings…I really need to check that out.

    Why manufacture such a heavy and slow supersonic projectile in 300blk? For hunting, or self defense, either 110 or 125gr pills are optimum.

    • Christopher Wallace

      in this case its probably due to the fact that federal already produces a 150gr fusion bullet. they prob wont sell enough 300 blk on this line to warrant a new fusion bullet design in a lighter weight

      • RSG

        Yeah- I did notice that their 308 offering was also 150gr and was probably the same bullet. I didn’t check the specs, but they are probably around 1700fps for their 300blk. I’d prefer something lighter and faster. Out of a 16″ barrel, the Barnes Vortx 110gr bullet can get up to around 2400fps. The only decent thing here is that the 300blk is the least expensive of their entire line. For folks like me who got into 300blk very early, it’s nice to see a much wider industry adoption, and subsequent lower pricing, virtually across the board.

        • Rick O’Shay

          I pay right around $21 for a box of their 150gr .308 Fusion, and it’s my primary hunting round. MSRP and real life pricing are rarely the same thing.

        • Christopher Wallace

          you’re right, lighter is better. wolf needs to make 300blk and you’ll be set

        • The 150gr .300blk makes even less sense when you consider that most expanding rifle bullets have a minimum expansion velocity of 1600-1700fps.

          So if the round starts off at 1700fps, it’s going to be a very short range hunting round.

          Even the Nosler ABLR, which has the lowest expansion velocity on record, requires 1300fps minimum.

    I do not understand the 150 grain bullet for the 300 BO. Everybody who uses them says the best bullet weights are the 110 and 120 range just like similar cartridges like the 7.62×39. 147-150 grain bullets are .308 and fit, this just seems like a .308 bullet in there. The low velocities of the 300BO mean that the design of the bullet has to be different, are they?

    I have read that the cutting edge 300BO bullet designers are approaching their designs like pistol bullets. This is because of the low velocities. It seems at first look that Federal dropped the ball, they went cheap and easy instead of doing the necessary work to produce a competitive and effective product. It looks at first glance that they are using .308 pills. They might be the same or slightly modified but they are not optimal for the cartridge as far as everything I have read and experienced as well as told to by 300BO reloaders and hunters.

    110-125 grain for supersonic and 180-220 for subsonic loadings. It all depends on so many factors though, OAL, barrel twist rate and length, hunting regulations in your state and so on.

    I cannot think of a reason to use 150 grain bullets other than it’s a .308 pill and cheaper to load.

    • Destro Yakisoba

      If the bullet expands at a low velocity threshold. Say 1400-1600fps it should be an effective short distance hunting load.

      • Big Daddy

        If, if it’s the .308 bullet it won’t….probably. it just doesn’t make sense after all the years of working this round by the gun people it goes against what I have learned.

    • iksnilol

      150 grain bullets have gooder ballistics compared to 123 grain in 7.62×39… so maybe it flies better?

      • Aaron

        This sounds like munitions for hunting so maybe it was a tested compromise on Federal’s part for a cartridge that will see usage only to 250-300 yards max. As long as the round shows results in their sponsored hunts then it goes into mainstream production.

  • Quasimofo

    I’m guessing the 6.5G Fusion offering is in a similar boat as the 300BO: using a bullet originally meant for a more powerful cartridge (260 Rem), but launching it slower (~350+ fps), affecting terminal ballistics.
