Hey guys, I just got my press set up (Thanks to Uncle Sam for giving me the money) and as a b-day gift my brother bought me 158gr 38's and TiteGroup powder. Referencing the data from my chart from the Lee auto disk, I threw a load and scale reads 3.3gr. Lee says TiteGroup should be 3.2-3.9 and TiteGroup's bottle says max 3.8gr. Will this load be OK? both my revolvers are 357's so they could take a bit of pressure. also what's the best way to test a scale's accuracy? The test weight it came with measures .02g light, could I pull a factory load and weigh that round? Main thing that got me wondering is the rounds my brother bought are 158's but they weigh 155gr according to the scale.
