Thread: 22-250 speed

    22-250 speed

    After testing some loads for my 22-250 and finding a good accuracy range between 36 to 37 grains of powder I strapped on the chronograph, I was quite surprised how the the speed differed but didn't seem to make a lot of difference to the drop at 200yards. What I am interested in is would the faster round be flatter shooting out further? Also interested in the speed other people are sending there 50grain V max bullets, the load I chose chronographed at 3600, which was slower than my mates 50 grain factory round, with the bigger charge it was travelling at 3840, I just don't see the point in using more powder to get the same accuracy?

    Accuracy isn't the whole story though. The faster a bullet of any given weight travels, the more kinetic energy it will retain downrange. This change in velocity could mean the difference between a clean kill, or a wound at extended ranges. If the slower bullet had more mass then the energy would be practically identical between the two, depending on how the velocity was tweaked.
    I soft-load my .270 to bring the speed down to around 2700fps. I haven't chrono-ed it, but I know if I used that round at the same range as a factory round travelling at 3060fps the downrange energy of mine would be significantly less. That's my take on it, anyway
    A Man should be wise, but never too wise. He who does not know his fate in advance is free of care

    When I started with my T3 Varmint (20 inch barrel) 22-250 I chrono'd some shop bought Norma 50gn Vmax at 3720fps
    I then loaded up 52gn A Max with Swiss RS60 powder and got the following average MV with 5 shot groups
    39gn powder - AVG 3421 ES 104
    40gn powder - AVG 3578 ES 62
    41gn powder - AVG 3688 ES 48
    42gn powder - AVG 3813 ES 46
    The tightest group was with the 39gn, (1/2 inch @100 yds) but the 42gn was almost as good so that's what I'm using.

    Cheers

    Thanks Bruce,

    I Know what you mean,with 36 grains I get 3600 AVG and using 37 grains of powder produces 3736 AVG, as both 36 and 37 are producing same hole accuracy at 100 yrds I'm tempted to now go for the faster round.

    It's a 22/250, it's meant to be driven fast.....

    However +/- 150 FPS at 22/250 speeds won't make a big difference in short range trajectory - which is what you expected to see at 200 yards but didn't....

    Just because you are paranoid, doesn't mean they aren't out to get you......

    The faster the speed the quicker you burn your barrel out.I get 3600 fps out of 36 grains of Varget with a 55 grain bullet.Quick and deadly enough.Richard.

    I'm getting around 3750 with 40grn of H380 on 50grn v max, cheers

    Im with others on this, too fast and enough rounds and your barrel wont last too long, however faster tends to be better for accuaracy , but this can change at distance, so Im sure I will be told Im taking ***** (again) but a 243 can carry more energy at 1000 yards than a 308 , mainly due to the efficiancy of the 6mm bullets v 7.62mm , but if your only shooting at 200yds, speed probably matters more, also the faster the bullet the more hydrostatic shock given ( usually) However at 200 yards just about any weight of bullet will kill a fox size animal at anything over 3000fps , zero at 150 and you should be ok

    Mine runs at 4050 fps average with Hornady superformance 50g ammo
