    Thank you! Just spent all my dough on a suppressor, though.

    You and everyone around you will like that you’ve got a suppressor. everyone that shoots my heat at our local range shoots suppressed and it’s awsome not having the muzzle blast and noise right beside you.

    I currently have one barrel but will be getting more.

    10Twist Maddco with conventional rifling at 30” length.

    I’m using RL23 with CCI BR2 primers and Berger 215hybrids 0.020 off the lands.

    Load is very forgiving with a sweet spot from 64.0 to 65.0gr. This yields velocity around 2900fps

    I can reach 3000fps with RL23 but feel this is pushing the brass so settled for the 2900FPS range.

    Next barrel will be looking to finish at 32” and a 9twist to give the 230’s a run.

    What’s your experience with Winchester brass?

    Hi. New to forum but a wsm shooter and love this thread.

    I have a Savage 11 action with a 24” Brux barrel in a choate tactical stock. 8-32x56 sightron s3. Kind of my longer range hunt rig but hasnt seen much duty. Its heavy at 16 lbs or so.
    Barrel is 1:10 twist and throated long for the 210-215 type long bullets. I dont recall how long the freebore is but with a berger 210 vld hunting, it touches lands around 2.406” base to ogive, or around 3.096” oal

    Right now i load mag length to 2.97, jumping around .135” i believe. It shoots 3 into a slight oval hole at 100.

    Norma brass, 215M match primer, 64.7 gr reloder 22, berger 210 hunting. 2790’s fps. Been to 65.5 gr but groups werent good. No pressure signs yet

    Re22 is temp sensitive. My load works nice in cooler to cold weather. Opens up some in the heat.


    Another load i liked was berger 180 elite hunters.
    Norma brass, 215m primer, 70.8 gr reloder 26. Book load to 2.900” oal. But shot 3054 fps in my gun and ragged hole at 100. 71.5 gr results in very stiff bolt and ejector mark

    Again, my gun with longer throat. Not sure if factory chambers would like it or see same type of results. Use caution

    I see a lot of long barrels, does anyone have any loads with short 18” barrels ?

    i want to hunt with this caliber and a suppressor is a must, hence 18” so it’s not overly long

    Got a lot of H4831SC

    My load ended up being 66 gr h4831 with 215 hybrids. Velocity of 2885 FPS sd in the zeros up to 2. Norma brass fgm 210’s .010 off touch. Going to play with seating depth more groups not what I’m looking for in the respect but zero vertical. Was hitting a 10” rock consistently at 600 yards. But I love bug holes!!!

    I second 66grs of H4831 but the SC version with the Berger 215 Hybrid and Fed 210M at .025" off, shot a 5.375" 5 shot group at 1K with 153 rounds thru the Kreiger 30" 1-10" twist 4 groove HV barrel on a Bat M action in Mcmillan MBR stock, hopefully I can do better with a little more practice.
