    What are the advantages with running a heavier bullet, say 210 gr plus bullet in my 30-06? 26" barrel, 1in10 twist, min SAAMI chamber. Currently running 168SMK, grouping well below MOA currently.



    Thanks.

    The 210 will retain velocity for longer distances.
    The 210 will have less wind drift as well.
    The 210 will have more impact energy at distance.

    With a 208 AMax or 210 Berger you will be able to make about 2800 fps via RL22 and a 26" bbl. VV N560 and Norma MRP should get you there too.

    The advantages of that over a 168 at say 2900-3000 fps are no mystery, it's just what Jeff said. A quick check via JBM will quantify the ballistic advantages.

    The key to maximizing the 30-06 with the heavies is getting the right powder under them to yield the potential velocities that the 30-06 case volume can produce.

    The 168 gr school of thought generally calls for medium powders like 4350, 4895, RL15, etc. When you step up to 200+ gr bullets you need to move up to a slower powder and fill up the case to get the most out of the chambering.

    When I read the OP first post it was MontanaMarine that came to mind. I have shot beside his 30-06 and know what he states about it is gospel. I was hoping he would see this post and chime in.

    Jeff, I had a feeling.......grin.

    I've never shot a 168 in my 30-06 so I couldn't give a comparison to a 200+ in field shooting.

    I have shot the following in the 30-06 with very good accuracy to 1500 yards or so, and even stretched it to a mile in good conditions.

    208 AMax - 2800 fps (26" bbl)
    208 AMax - 2720 fps (22" bbl)
    210 Berger - 2800 fps (26" bbl)
    220 SMK - 2750 fps (26" bbl)
    240 SMK - 2620 fps (26" bbl)

    RL22 was the propellant in all of these, and bullets moly'd.

    Recently I've been shooting the moly'd 208 AMax over RL17, getting 2740 fps from 22" bbl at 70F.

    Anyway, these are a few bullets that have really worked well for me inthe 30-06, to distances well beyond 1000 yards.

    The Berger 215 should really do well too. I'd guess it can run at least as fast as the 208, maybe even a little bit faster given the bearing surface. Then there's the Berger 230, I'd guess 2650-2700 fps from a 26" bbl.

    So many bullets, so little time........grin

    If you are able to stretch your rifle to 1000 and beyond on a regular basis, try shooting a few of the heavies beside the 168, and the difference will be very evident, especially if you have some wind. If you seldom get past 600 yards or so, the beauty of the heavies will probably not be fully appreciated.

    A 210gr Silvertip will plow a moose. DEEP penetration.

    Thanks for the info guys. Are there any aspects of the chamber (throat, etc) that could be a limiting factor and I need to be aware of when I start looking into the 200+ gr bullets?

    MontanaMarine, you guessed it - I am wanting to stretch it out there. And yes, currently using H4350. Got both the RL17 and 22 so we are GTG there.

    I've got a standard chamber/throat. I'm loading to 3.40" oal, just off the lands.

    With the moly'd 208 in Win brass I'm loading 61gr RL22, or 55 gr RL17, and CCI 200 primers.


    Keep in mind my throat has roughly 4500 rounds down it. So as always start lower and work up with normal cautions.

    Here are my load workup notes with the 208 AMax, with RL22 and RL17. You can see I had pushed up a couple grains higher than my working load, to see where I would start seeing pressure.

    Hornady 208gr AMax, moly'd
    Brass: Win
    OAL: 3.46" (3.47" OAL kisses lands, 15Feb08)
    CCI-200 primer
    Reloder-22
    60 gr - 2660 fps - 57K psi (22.5” bbl)
    61 gr - 2710 fps - 62K psi
    62 gr - 2765 fps - 66K psi
    63 gr - 2800 fps - 70K psi, flattening primer
    64 gr - 2850 fps - 74K psi, flattening primer, brass flow in ejector, .002" web expansion
    Reloder 17
    55 gr – 2740 fps (22.5” bbl)
    56 gr – 2760 fps
    57 gr – 2810 fps, (slight brass flow in ejector)

    Do you have the load data for the 210 by chance? Also, if you start loading up the 215, any idea what powder you would start with and a good starting load?

    I loaded 60gr RL22 under moly'd 210 Bergers, 2800 fps from 26" bbl.

    With the 215 Berger, I'd moly it up, and start around 58gr RL22, or 52gr RL17, in my rifle.

    Every rifle is a little different. With a rifle I was not familiar with, I'd likely start around 56gr RL22, and 50gr RL17, and work up from there.

    Thanks a lot for the info! I've been contemplating throwing a long range round together for my '06 for some antelope hunting for a friend. I might have to do some experimenting with these considering the results you are getting!
