Looking hard at the 210-215 bergers currently.
The 200gr eldx shoot good.

215 Berger for .300 WM/WSM.

Any reason over the 210?

200 grain eldx, rl22 (will probably try staball hd when I'm out) 215 federal gm, and peterson brass gives me 2880 fps from a 26" barrel.

Im seeing 2900 fps in factory ammo!

I prefer the higher BC of the 215. The hybrid is also more forgiving than the VLD, at least in my experience.

I have some room to go up in charge weight but I'm right around 1/2" groups. Higher chare weights definitely had accuracy under 1 moa but not as good as my current load.

600 yards yesterday in the rain at my local club. 215 hybrid over 77gr of h1000 and a federal 215m in Norma brass. Running a touch over 2900 out of a 26" 9 twist bartlein.
Full disclosure, I had a first round hit and the wind shifted to head on and I put two over the top. Readjusted, 4, 5, and 6 were hits. That's an 8" target.

This was last weekend, 212eldx, 75.9gr of magpro, Winchester LR primer, R-P brass. 2880ish.
Same 8" target at 600. Same rifle.

Sammi spec chamber or custom throat?

Sammi spec chamber or custom throat?

Saami chamber throated for the 215. I shoot the 212's mostly at steel and save the 215's. I recently got some more 208 eld-m's. I need to revisit that one. I think they were running around 2930 when it was new. I've got to add up this weekends round count, but I think I'm getting close to 450 down this one. I've had it a little over a year now I think.

The US government purchased MK 248 MOD 1 .300 Winchester Magnum match-grade ammunition in 2009 for use in adapted M24 Sniper Weapon Systems and other .300 Winchester Magnum sniper rifles like the US Navy Mk.13s. This ammunition was developed as a .300 Winchester Magnum Match Product Improvement (PIP) and uses the 14.26 g (220 gr) Sierra MatchKing Hollow Point Boat Tail (HPBT) very-low-drag bullet fired at a nominal muzzle velocity of 869 m/s (2,850 ft/s) ± 15.2 m/s (50 ft/s). According to the US Navy this ammunition should increase the maximum effective range of .300 Winchester Magnum sniper rifle systems to 1,370 m (1,500 yd), decrease wind deflection on bullets in flight and use a reduced muzzle flash propellant that remains temperature stable across an operational temperature range of -32 °C to 74 °C (-25 °F to +165 °F).

Have two 300 WMs. One has a 26" barrel (Sako 85 rebarreled by LRI) and the other is a factory Sako S20 with 24" barrel. Both can shoot the 215 Bergers sub 1/2 MOA (if I'm having a good shooting day) with either H1000, StaBall HD, or Ramshot Magnum. Ramshot Magnum seems to provide the best velocity and best accuracy even when I mix up brass (ADG, Norma, Federal) and large rifle magnum primers (Federal Match, Fed Standard, Winchester and CCI).

Favorite load that shoots great in each gun is:

215 Berger
ADG Brass
Federal Match Large Rifle Magnum Primers
79.0 grains of Ramshot Magnum

Just have to adjust the COAL based on magazine length

Sako 85 = 3.660" (magazine length is 3.70") = 2,900 FPS
Sako S20 = 3.555" (magazine lenght is 3.60") = 2,800 FPS


Oh yeah, I can switch out the above load with 212 ELD-X's and keep everything else the same and get the same accuracy/velocity. Just prefer the Bergers.
