The 25 Copperhead is what originally got me thinking about a 25-223 cartridge, building one has been on my mind for years after reading John Wooter's(?) articles. The 25-45 Sharps is nice as it needs no trimming or forming other than running a .223 case into a 25-45 die and you are ready to load, being that Sharps had dies made they are available at a much better price than other similar wildcat dies. They had both RCBS and Redding sets available and i went with the Redding set. I really enjoy my Marlin 25-20 but it will be nice to have scoped bolt gun loaded to similar ballistics, once i get going with this rifle i plan on having Lee make me a collet neck sizing which will make reloading very quick and easy. I really look forward to seeing what i can do with the hollow pointed 257420's, while i can drive them pretty quick out of the Marlin the higher pressure loads certainly shorten case life so i never shot a lot of them at higher velocities. It would be fun to find a 2000fps load that shot well out of the new rifle, at 1800fps those little hollow points will rip a red squirrel in half with a body hit and literally decapitate a rabbit with a head shot. The old Lee group buy bullet is great when loaded to 1400fps and very quiet but effective and makes a great alternative to outrageous priced .22's for plinking and bunny hunting. That 6 gang mold will really crank the bullets out quick and makes a cheap load to shoot, been using 9gr's of surplus Data 68 in the 25-20 and it will probably only take another grain or two to achieve the same velocity in the 25-45.
