    jimm,
    Your are right on the BC for the 180's. I have only shot 98 rds thru my 300 mag, so I am not going to give you much from this end.
    But, I have read several times that the 200 gr bullets or maybe a 220 will usually do very well in the 300.

    Re: 300 win.mag bullets

    I have shot a variety of .30 cal bullets in my .300 Winnie.
    I would stick with the Sierra MK's,
    Accubonds, or Barnes TSX.
    RL22 gave me EXCELLENT velocity, but accuracy was so-so.

    The old classic's IMR4350 or IMR4831 is still my go to powders for a .300 Mag. I like Fed 215M primers too..sakofan..

    I use 69,3 grains of IMR 4350 powder with 180 grain corlokt seated 3.340 on the chron average out 2980 I can hold a 3 shot group in a square inch at 100 yds.

    Re: 300 win.mag bullets

    thanks gonehuntingagain, your post prompted me to recheck my velocity with that load and good that i did. velocity hovers around 2975,10 or up and down.i do not have any overpressure signs. will probably try seating out a little further and check vel. and watch for over press.what is the fastest a nosler 180btbt caqn be driven out of a 26 inch barreled 700 rem.factory barrel /action?will drop aline when i check out the new changes. see ya, jimm

    I'm not sure what the max velocity would be with IMR 4350, If I remember correctly, I think I have seen books list 3100fps (I could be wrong though). It will vary with the rifle, temperature, elevation, etc...Just get them dialed in such that they group well and have a low spread in FPS with each shot and go from there. Speed won't matter much if they group so poorly that they barely hit the target.

    gonehuntingagain, howdy! you know,iknow what the books say,however, i am looking for real world experience with similar equip. so far it seems that that the best you can do with my current setup is 3050 fps regardless of the powder/ primer/seat depth/etc.i suppose i'm looking for the magic combo,you know, the one that can drive a 180 bullet at or over 3400 fps., out of my rig.of course , accuracy is preeminent.many thanks ,jimm
