    Magneto Speed Alternate Mounting Options effectiveness.

    @Mr.BR I was doing testing and break-in on a new barrel for my 6.5-284.. it dumps a lot of gas and un-burned kernels of R26 because they gave me the wrong twist rate and the bore feels a bit oversize as well.. its on its way back to be looked at.. but here was an interesting fiding my...

    Magneto Speed Alternate Mounting Options effectiveness.

    @Stpilot12 my AR has less POI shift than my 2 heavy barrel 308 and 6.5-284 rifles... 1 because with the AR the barrel isn't tapered and the bullet isn't flying into a rising ground plane, 2 it has a brake and therefor not as much muzzle dump gas to interact with the projectile while its over...

    New Magnetospeed Mounting option

    @lash I have not done someone elses homework since 1984 and I can assure you she was alot hotter .. that said first.. the paper is not my research, but was required reading, it s peer reviewed and I believe the data to be sound .. and again, pilots feel this ground effect on every takeoff and...

    New Magnetospeed Mounting option

    @TacticalDillhole the width of the plate/wall/ground makes no difference.. the shockwave is 360 and its the wave directly beneath the bullet.. in theory the bullet shot over a sewing needle laying longways would even have an effect I get a .8 to .9 MIL (3+ inches at 100) shift in my group...

    New Magnetospeed Mounting option

    @TacticalDillhole also.. if you even have one.. try mounting it a 6 o'clock.. groups move up.. on every rifle and caliber I have and the bigger faster the bullet the more the deflection.. especially if there is any angle on the bayonet.. now move it to 12 o'clock .. the groups go down... move...

    New Magnetospeed Mounting option

    @TacticalDillhole ... living up to your handle.. eh.. you must be one of those world is flat kinda guys where science and math were not strong points.. yes.. the surface will deflect the projectile ... the width is more than enough given the hight prescribed by magentospeed to be less than...

    New Magnetospeed Mounting option

    barrel harmonics are only a small part of the induced error of the bayonet attachment. the aerodynamic friction and interference between hypersonic object (bullet) and raised ground plane (bayonet) pitches the bullet and will effect its POI. distance above the fixed surface, caliber, velocity...

    Magneto Speed Alternate Mounting Options effectiveness.

    The projectile was discovered to experience a marked pitching moment, initially nose-downwards at the high end of type C reflection interactions, then more strongly nose-up with contin- ued decreasing ground clearance, as the pressure distribution over the rear of the projectile was increasingly...

    Magneto Speed Alternate Mounting Options effectiveness.

    now.. include the hypersonic gases exiting with the bullet and the explosive wave formed by the combustion of the expanding unburned fuel to the picture and you have quite a mess

    Magneto Speed Alternate Mounting Options effectiveness.

    @Mr.BR also had been seen many times in the design of muzzle breaks and suppressors.. if I recall correctly.. for best accuracy there needs to be .020 for clearance and it must be perfectly concentric. or guess what.. it deflects the bullet.. even if it doesn't strike the brake in this...

    Magneto Speed Alternate Mounting Options effectiveness.

    @Mr.BR because I know aerodynamics and while your finite analysis of barrel whip explains some things.. it doesn't cover the aerodynamic friction that occurs to a body traveling at mach 2-3 passing less than .3" from a interference surface...

    Magneto Speed Alternate Mounting Options effectiveness.

    @Mr.BR I don't know what caliber you are loading for.. I tried R17 in 6.5Norma.. it was a bit explosive for my tastes and it didn't take much to see pressure spikes at velocity less than 3000 on a 26" barrel.. went to r- 26 and got north of 3150 without pressures signs and called it quits...

    Magneto Speed Alternate Mounting Options effectiveness.

    @Mr.BR yes.. there is certainly the barrel tuner effect.. but there is the aerodynamic interference with the bayonet face as well.. again.. if it was just weight.. rotating the bayonet would not change anything (the weight is in the same place.. turning a BR tuner moves the weight back and...

    Magpul AICS 10 round mags??

    @CavScout I find they work great in 308... I got the rifle with one accurate-mag 5 rounder and it fed hard.. needed some lip angle adjustment and it was still scratching brass and took a good push when fully loaded.. polished the lips and it helped a bit but the magpul is like butter.. the...

    Magpul AICS 10 round mags??

    @cattleman99 well could be worse.. you can still GO to the match.. I ordered a barrel back in Nov... first one came in Jan.. throat look liked it was cut by a 12 yo a six pack into happy hour on friday.. sent it back.. been trying to break in the second barrel that came back in may...

    @cattleman99 you could buy a whole bunch of 5 rounders...

    Magpul AICS 10 round mags??

    sorry.. all the vendors on that list that say they are in stock. are in fact out as well... .... that escalated quickly...who the hell is hoarding these things... @wigwamitus wanted 10.. who the hell carries 100 loaded in aics... hehe...
