[QUOTE="jdyoung, post: 2196853, member: 113391"] [I][B]Brisance is the shattering capability of a high explosive, determined mainly by its detonation pressure.[/B][/I] The CCI 250 as I know it, was considered among magnum primers a [I]Mid Grade Primer[/I]. You will likely do just fine using it in place of the FED 215's till they come back on the market. And you'll have educated yourself in that area. After reading an article about Primer Brisance by John Barsness, I found the chart shown below and it is what I've used for reference when switching primers. For years the FED 215 was considered the most powerful primer as it was the first primer for magnum use. ( Weatherby's) My personal belief is that , once it was developed, the WLRM primer is on the same level as the Fed 215, maybe a touch higher . This is because for many years Winchester did not manufacture a magnum primer. Their WLR primer was used for standard cartridges as well as [U]Large Rifle Magnum Cartridges'[/U]. As long as it was safe, I don't think Winchester wanted to take a back seat to Federal So , heed the warning included with the chart.
