Thread: Which powder? 20" .243 85gr hpbt

    Which powder? 20" .243 85gr hpbt

    I'm looking for a suitable powder for the above combination for roe and fox. Was going down the line of IMR 4064 but would I benefit from a slightly faster burn rate powder?



    Thanks for your help

    38gr of Vhit N140 works great for me in that bullet weight.

    40gr of H380 with a Federal Mag primer does it for me with either an 87gr or an 85gr bullet

    Vit n160 for me.

    Have a look at the thread about shorter barrels needing faster powders. N160 in my 20" barrel only burn 85-88% of the charge and struggles to get the velocity stated. N140 would be better. IMHO

    I've purchased a tub of IMR 4064 which is slightly faster again than N140 although there's minimal difference. It seems to have a good following combined with the SGKHPBT so I'll give it a try.

    N160 in a 20" Sako 75 with Speer 85 grain SPBT, standard primers, 3,100 fps with no problems and very consistent.
