[QUOTE="AZShooter, post: 2049368, member: 5219"] Great write up Swamplord! Sure gets a wildcatter thinking. I remember reading about the 284 when it came out in 1963. There was a "flurry of activity necking it up and down" After it was all over the 25-284 and 6mm-284 were the favorites of the gunwriters. At that time the 6.5-284 was an oh hum cartridge. Funny how things change AND repeat themselves. Enter the 6.5 RPM and we get to do this all over again. I have a LA Rem chambered for a long throated 284 win. 1 in 7 twist 28". Accuracy load with 180 berger hybrid is 2800 fps. According to the 1/4 capacity rule a 7mm RPM should yield approximately 2925 fps. That puts it close to 7 rem mag performance. I have the 284 reamer, need to figure out if it will work or requires regrinding. All would be straight forward with minimal cost except the dies. I heard that there are other RPM caliber offerings in the works. Specifically the 7mm and the 308. Would like to see that happen soon. Then dies and formed brass will be available. [/QUOTE]
