6.5mm/284

I am planning on hunting varmint and big game (deer size) with this rifle out to 1200 yards I figurd the bullet would have over 600 ft-lbs of energy would this be enugh energy for the deer size game? I would like to use the 142 6.5mm MK would this be a good bullet choice. Sierra has the BC on this bullet at 595 is that correct? The rifle is a hart action with a 1.25 to .900 28in 1-8.5 twist Krieger. What powders should I start with?

    Three basic powders work well in the 6.5/284 witrh 142 or the 155 Gr Sierra.
    1. H4831 SC
    2. H4350
    3. RL 22

    We try not to drop below 900 FP of energy if we can for elk. It don't take much to kill a deer especially when they are not expecting anything from afar.

    Thank you for the powders. I will try the H4831 SC first with the 142g SMKs what have you used for a powder charge with this combo in your riffle? I was going to start out with around 51g and work up from there. Do you think the 155 is a better bullet, what is the BC?

    49 to 52 grs with any of the powders mentioned will work with the 142gr.

    The 155 has a higher BC but, you might just like the 142 a bit better.

    I looked up the BC on the 142 SMK and the 155 SMK

    Sierra MatchKing Bullets 6.5mm (264 Diameter) 142 Grain

    Diameter: .264 inch
    Bullet design: Jacketed hollow point
    Sectional density: .291
    Ballistic coefficient: .595 above 2850 fps, .580 from 2800 to 2400 fps, .575 from 2400 to 2050 fps, .550 below 2050 fps


    Sierra MatchKing Bullets 6.5mm (.264 Diameter) 155 Grain Hollow Point Boat Tail

    Diameter: .264 inch
    Bullet Design: Jacketed Hollow Point
    Sectional Density: .318
    Ballistic Coefficient:


    .570 above 2800 fps

    .560 from 2800 to 2000 fps

    .555 below 2000 fps

    The 142g looks better until it gets below 2000fps. The velocity of the 142g would go under 2000fps around 700yrds then the 155g would have a .005BC advantage. I will half to get some of both of these bullets and see witch one performs best in my rifle on the longer shots. My barrel will be here in about a month. Thank you for your help?

    Very Low Drag
    Recommended twist rate is 1/9
    Ballistic Coefficient is 0.627
    Boat tail

    I looked at bergers web page and ran the .627 BC on my program and it looks impressive. Has any one used these bullets on game? If so what did you think of the performance?
