    Cast bullets in a 22-250

    Any of you guys using cast bullets in a 22-250, i have 44 and 55 grn moulds for my hornet, andi am using 55grn jacketed rounds in my 22-250 so obviousely wondering if cast bullets with gas checks would work in it
    will definately try it but was wondering if there is anything i should look out for
    Cheers in advance

    I did a lot of experimentation with high velocity cast bullets and 22-250 was one of the rounds I used. For best results, do a chamber cast and size bullets to .001" under throat diameter. Seat bullets to snug into the rifling. Make them as hard as you can (I heat treated) and then use the lowest pressure powder you can and don't exceed the yield strength of your alloy. Lastly (firstly??) make sure your barrel is scrupulously clean of copper jacket residue. I got moa and slightly more at 2800 fps using heat treated wheel weights from a custom Mauser Varmint.~Muir

    Many thanks for the tips will give it a go and post the results, somehow knew you would come up with an answer
    to heat treat the bullets do you just drop them from the mould into water ???

    Cheers
