Unis Ginex Large Rifle Magnum Primers Box of 5000

3 stars

Reasonable price for a product that was seemingly unavailable elsewhere.

I went out and did a load test between these and another popular (LRP) primmer. Platform is a 6.5 CM American Rifle. Used same brass and identical powder loads. At some powder charges these had a slightly higher MV but with higher ES/SD. As I increased charge, the two primer's pretty much matched up same MV,ES and SD. These were about 10FPS higher in MV but ES/SD were 12.6 to 12.4 ES and SD was 5.2 to 5.6. At 40.0gn, these shot a 3rd group at .228 MOA and 40.3 the other primmer shot a .274 MOA. I had no issues seating the primer's and de-capping them. I would buy them again. I was using Peterson brass and N550. 20 inch barrel.
