Re: RCBS 5-0-5 or 5-10???
Any particular reason you chose these two models? I would go to the RCBS Chargemaster. No need of a powder measure or trickler (it's all built in). These scales are the best thing I've bought in reloading equipment in 20 years! The measurement is precise and very quick. You will definately speed up your process and be accurate as well on the powder weight if you go with the Chargemaster. Worth the initial investment. Try out cabelas for one of the best prices.
