I feel you on the NC weather. Saturday was brutal to shoot in and keep the barrel cool. Luckily my buddy 3d printed me a chamber fan and I also had a Milwaukee battery powered fan to blow on the rifle which all helped.
But onto the load development I did:
Vit N565
56.5g, 57g, 57.5g, 58g, 58.5g- 3rds each
143 ELD-X
2.340 BTO (forgot to record OAL)
Lapua brass (brand new brass)
CCI 200
Very slight ejector swipe on the 58.5g load. I feel confident I could go to 59g and be fine. Velocity and pressure was my main data goal since I still hadn't found pressure on my handloads in my new Seekins yet and had never tried 565 in the rifle. SD was great for most part. Going to tweak BTO a little and give it another go when I get free time to head back out.
