Quote:Hello All,
Well, received the 5.6x61R cases and modified them to rimless. 5 minutes per case ... 3-1/2 hours to modify 40 cases. here's the steps involved. This has been the most time-consuming project I've had the displeasure to tackle.
WARNING - WARNING
If you look back at the pictures of my modifying cases from "rimmed" to "rimless", you will see how I modified them.
Unfortunately, there was a problem. I cut the groove too wide and started to have cases "BLOW OUT". Fortunately the gun wasn't damaged. I tried cutting a more narrow groove, but had another case "BLOW OUT" with the second loading. The Bertram rimmed brass has a sharp interior corner - standard rifle rimless brass has a radius interior corner. I have now switched to reforming PRVI 25-06 brass into 5.6x61 caliber. The heads of the PRVI 25-06 are only .005 smaller and formed to the chamber nicely. Most other brands of brass were .008 to .100 smaller. But most important is there is a large radius at the interior corner. Now, all is well.
