Does anyone see a difference using different primers?

[QUOTE="Turpentine21, post: 2919847, member: 124909"] I had a 308 load with Varget that grouped far tighter with cci BR 2s than it did with Federal 210m. Es and SD were better too. Standard Winchester primers have always been a bit hotter for me than BR2s or 210s. Also, where I see a substantial difference in different primers is with 6.5 Grendel. Cci small rifle magnum primers produce more velocity than Federal 205s for me but the Federal primers groups are smaller and have much better ES and SD numbers In that particular load. Tighter stats make a huge difference when it come to long distance and vertical dispersion. [/QUOTE]
