Thread: 22/250 Groups

    22/250 Groups

    At last !! I've managed to get some tidy groups out of my new Winchester 70 Coyote light. After nearly a full 1 lbs of Benchmark gone !! It settled on 33.5g a 50g v-max and an OAL of 61.5mm which gives me just less than 1/2" at 120 yds, and on 250 yds the groups open up to around 2 1/2" ! Is that about the norm for the 22/250 at 250 + yds ?? Thank's..

    don't get hung up on groups mate. that would be a dead fox at 250 yards. i have used abit of benchmark in my old 22/250 and couldn't get on with it.
    varget or imr 4007 ssc is what i use now.

    pushing a 50 grain bullet. great speed and accuracy. get out and injoy

    Done a few loads with varget and not too keen as yet, but will continue !! Strange thing I've noticed is that no matter what grains of Benchmark i use (32 - 36g) i get craters on the primers, and as per equivalent load of varget there's no sign of any !!??

    what primers are you using in it. is the bolt stiff to lift on the benchmark loads. if so i would back off a little.

    CCI BR-2, Hodgon states max load of 36g, but have had craters at 32g !? No, bolt seems fine, thank's Jay..

    There are a myriad of things that would cause this including the fact that "max" isn't an absolute. Different LOT's of powder react differently, etc. Assuming your cases are trimmed and the necks aren't too thick, I'd change primers and work up from the bottom again.~Muir

    Back to your group question....
    Depending on what scope you're using you may improve things by using a target more suited to your reticle. Also - if using fixed px cheekweld must be consistant otherwise groups will open up.
    You should be getting 1" at that range in ideal conditions.

    From what I could discern, you're OK. Switch primers at some point and give it a test.~Muir
