I load with both SP and SP mag primers. When I work up a load I use a chronograph to get the powder charge to where it needs to be. Then I try both SP and SP mag primers to see which delivers the lowest standard of deviation. Some powders like standard primers and some work better with mag primers ...

Bob,

I adjust the shell plate by turning the bolt down until it is finger tight and back off as little as necesary to let the plate turn freely. I test this by cycling the press while I hold the shell plate bolt from turning. Once I'm happy with the shell plate bolt clearance I raise the platform ...

I've bought it at Sportsman's Warehouse. Best to call to confirm they have it in stock first. Expensive but really clean burning.

Corn cobb media will give a higher polish to brass than walnut media. Walnut media is more abrasive and will remove heavy tarnish. I buy both from an industrial sandblasting supply house. Comes in 50# bags and is much cheaper than the stuff sold for reloaders. Store the excess in 5 gal buckets or ...

Late to reply but the road in to Imapct Zone is in good shape. Phil has done a lot of work on the range and continues to make improvements. Currently he is completing a stats shack/classroom in the center bay adjacent to the container.

I use Excel. It works. It's widely available. Does everything I need. I can sort on a particular powder, primer, bullet weight, etc. to see what I've tried and what worked. I have one workbook for rifle and a second for pistol. Since I load some cartridges for several different guns I have one ...

I rely on standard of deviation to evaluate pistol loads. If you have a SD of 10 this means that statistically 68% of the velocities for that load will be within +/- 10 fps of the average. If you expand the range to 2X the SD (+/-20 fps) 95% of the velocities will be within that range. Although not ...
