300 prc 220 eldx load development

[Russell123523]

I've started load development on a 300 prc with limited supplies available I found 200 220 eldx which wasn't my first choice the only powder I have enough of is rl26 the gun is a bergara wilderness ridge 75 grains is giving me .75 to 1 inch groups 2900 fps . I haven't tried different seating depths yet to see if I can tighten it up any Im .020 off now. Just curious if anybody is shooting this combo. I have also noticed the bullets weight varies from 218.7 to 220.8

9 twist?

What elevation are you shooting at?

Bergara is a 1/9

Hmm. If your ES is fine, I wouldn't worry too much until you get the components you want. I suspect that gun (9 twist) will shoot 200-215 grain class bullets better than 220.

Also, purely shooting at 100 yards can sometimes be misleading from an group size perspective. Go shoot it at 300-500 yards and see what it does.

Thats some good speed. I'm hoping to push the hammer 214 out of my 30 Sherman over 3100 and by your finding I should be able to do that.
Rl26 should be a good powder. That or rl33.
With the heavier round rl33 may gain you a bit more
