Hoping you some great success like I had with these. Built arifle with a 20” proof barrel.
- Using
-Lapua SRP brass
-CCI 450
-47gr RL26 (USE CAUTION, not liable for sharing educational info. Use your due diligence when building your new loads)
-loaded to 2.247 CBTO / 2.939 COAL
I am achieving roughly 2880-2900 FPS. Great 5 shot grouping and one shot on a Elk cow which was DRT at 400 yards.
RL26 and CCi 450 is nearly extinct currently though
The tough part is meeting the COAL in your set up it seems. I’m loading pretty long but using MDT AICS binderless mags I can max out at 2.955” if needed.
