So I'm looking for the tool which I can use to sort my bullets, I have 3 calibers which I regularly reload they are .224, .277 and .308, and it looks like there are 4 or maybe 5 choices, the hex tool from Sinclair, hex tool from PTG, then Sinclair Bullet Sorting Stand with Dial Indicator, Sinclair Comparator which attaches to the caliper and Hornady LNL Comparator which was originally made by Stony Point. So I need to choose one and I'm leaning towards Hornady LNL Comparator. Do you think I'm on the right track? Maybe there is something I should know before I buy one? Thanx!
