6.5 Creedmoor Large Primer Lapua Brass

I will be reloading 6.5 Creedmoor Large Primer Lapua brass and have a question regarding primers. Has anyone done testing to see if a FED 215 Mag primer will produce good grouping? After giving this some thought, I‘m wondering if the FED 210 would be a better choice? I’m wondering if the FED 210 primer will yield higher velocity and tighter groups due to the lower pressure. I look forward to any help you can provide.
Both work, run what you can find. the case was designed for standard, non-magnum primers, but Ive used both with equal results. Powder charges will change a bit with the magnums, but Ive not had any issues with ES or SD going between standard and magnum
215's will work better if you use a borderline too slow powder like Rl26 or H1000 especially in winter temps. Otherwise standard primers typically give better deviation numbers better suited beyond point blank range.
