    I shot some loads in 300 wm with 210 vld's with RWS brass , 78 grains of H-1000 for 2974 fps then went to nosler brass and with 79.5 grains H-1000 was 2940 fps I had no pressure with either. Is this the norm with RWS brass? It filled the case way more than nosler but I was shocked at the difference in velocity and I know someone will give me the reason other than thicker brass.the real question is which to go with, I can go up in nosler brass but at the above loads they both shot very good.

    The RWS is regarded as the best brass you can get for thr 300 WM. And yes, the reason RWS holds less powder is due to the wall thickness. It also means you'll max pressure with less powder. I' d run the RWS. More velocity with less powder consumption what's not to like?

    the only thing not to like is they are hard to get.I guess you can not expect cheaper brass to be the same but you can always try

    Don't worry. As long as you take care of your brass that RWS will last a very long time.

    I have loaded that load ( less powder) in many 300 wins with 210 Bergers. Both customs and also several factory senderos. I have used RWS, WW, RP, Graf, and Lapua brass. I feel you are flirting with over pressure loads. The reason the RWS is showing more velocity is it is indeed a higher pressure load even at one grain less. The lower case volume of the RWS makes the load you described close to 100% full depending on seating depth. I find max with RWS and a 210 Berger and H-1000 to be closer to 73 or 74 gr. I am not sure of your barrel length or the altitude you are shooting, but if you are under 4000 ft als. and in less than a 28" barrel please be very careful.

    I am low and you may be right. I don't have anything that would make me think there is excessive pressure. Primers, bolt lift , and no flash marks. I will load some down there but I am afraid I will be in the 2700 fps range. With nosler I could easily go to 81. Grains but I only want to be over 2900 fps.

    Even in the larger volume cases like WW, RP, and such 81 gr and a 210 is pushing it. 77 or 78 is probably max. Rifles are different, I am stating the normal charges. We have found we need to reduce the load by 3 gr when we put it in RWS.

    2900 plus from a 300 win with a 210 is smoking at sea level. What length tube?

    28 inches I will try the nosler at 78 and the rws at 75.5 and check velocity

    I just started working on loads using the 210 VLD's with H1000 with Norma brass and 215 primers. Out of my Rem Milpecs 24" barrel I'm running 2700 FPS and planning on working up my charge. I'm .010" off the lands. Since I was breaking in my barrel I kept the charge light. I would like to see 2800-2850. I will say that the the rifle is shooting .2-.3 MOA at 200 yards with SD around 10. I'm hoping this holds as I work on boosting the velocity. Any viewpoints on the Norma brass? I got hold of 200 pieces. It's all I could put my hands on during this supply drought. It's not cheap, but so far I like it.

    The Norma Brass is comparable in volume to Lapua, WW, RP and Graf. I feel you will end up is the 77 gr area depending on your lot of H-1000 and you should see 2800 plus depending on altitude from your 24" tube. The accuracy should also be good there and I like your starting depth.


    If you feel you are just a tiny bit hot, once you get there on the charge but have good accuracy, try backing off .010" at a time and see if pressure drops a little at .020 to .030" off the lands.

    What loads have you tried with the h1000. I was trying with rws brass and it appears I am to hot. I have no signs but I am going to try a little less powder. I have seen some loads at 80 grains in Winchester brass but those may be over pressure also. I don't care if I am a little lower in speed but I don't want to get so slow that I am 300 h&h velocities.berger book has max close to 76 grains and I have found all of their loads very mild and no where near the velocity that they quote
