ADG brass
RL26
215 Hybrid
76 gr. RL26
FGMM
.030 Jump
26" 1:9.3"
2925FPS

This is not some outlier crazy group I have shot some smaller including a 3 shot group at 100 that the hole barely got any larger. By far the easiest cartridge I have ever messed with.

with those bullet weights and h-1000 and 3.600 oal. start at 78.0 and work up.
that is a high end 300 win mag load. I entered the 300 PRC in my quick load and quick design and that should get you started.

Running a 24" 1:9 with :
78 grains h1000 I was at pressure with Fed 215M primers at averaging 2887 fps.
78 grains h1000 CCI 200 no pressure at 2865 fps

I think the factory are loaded with RL26.
I found a pretty huge swing in the factory ammo powder charges. Average was 74.5 with a 3.2 grain difference from high to low. definitely using Fed 215s from factory. Book weight for RL26 came pretty close to actual velocity. I pulled apart the last 80 of 200 and weighed each charge and messed with different charge weights.

As mentioned 78gr h1000 was pressure in my setup with .020 jump using 225 ELD-x so you may consider starting slightly lower.

I'm loading For my 300prc Mesa Long Range with RL-26 75.5 grains with Sierra 220 match king 215 federal primers 2875 FPS getting 1/2 groups at 100 yards have taken it to 1000 yards With ease 22.4 MOA

Got lucky ! I'll shoot a few awesome groups with this particular load but can't pin point why it's inconsistent. For whatever reason my N165 loads have been the most consistent so far. Haven't had a huge amount of time to really settle in on one particular combo just yet.

Factory Bergara b14 hmr 26" barrel
212gr eld-x
Once fired hornady brass
215m primer
80gr IMR 8133
Shooting around 2860fps

I'm still playing with this load but I shot a 5 shot group this past weekend 4 shots measured .345" with a flyer on the 2nd shot.

My buddy has a b14 with the 28 inch barrel I load for him. I load 205 Vlds and 208 eldms the gun really liked rl-23 with the vlds and is pretty solid with the eldms with 77.5 of h1000. 1/4 moa at 100 and 3/4 at 200.
