For load development i should be better off than starting fresh with virgin brass right?? Looking to sell the original rifle
Yes, new rifle = new brass to get the most out of the rifle, the brass, and the loads because this reduces a lot of potential variables. I run a short ladder and find a virgin brass load that's good enough to shoot through the cases, and then will redevelop a long term load once the brass stabilizes.
Unpopular maybe, BUT yes I will also occasionally use brass in multiple rifles. When I do this I'm not trying to make uber-benchrest high-precision ultra-extra-long-range American-sniper win-the-match quality loads here. Sometimes you just need to make a gun go "bang" - low-powered loads for a new shooter, using up random/ spare components, shooting hogs under a feeder at 50 yards. There are a bunch of situations I've been in where I'll grab some random 30-06 cases (maybe even mixed headstamp
), FL size in a tight die, drop in some 4895, stick a Hornady Interlock on top, and go shoot. Faster than a trip to the store to buy a box of Core-Lokts.
Definitely don't trash the brass, it's always worth having spares around, especially if you're just getting started.
