flyrodr1948

I posted this in the Misc. Beginners forum, but I think it is probably more appropriate here: I inherited a 1988 RL550 from my brother who passed away in Sept. It had been sitting in a box in his garage for 10+ years. I would like to put it into use, but have no experience with progressive reloaders, only familiar with my old RCBS Rock Chucker single stage. How does the RL550 (1988) compare to the current 550B? Will the current components fit my old press? Tool Heads, Caliber Conversion Kits, Powder Dies, Index Pins, Powder Measures, Powder Funnels, etc? What is the low primer feed tube (electronic) sensor all about? Is it an upgrade that is purchased? Is it a retro fit device? Same question about the low powder measure indicator (electronic)? Would Brian's "As It Should Be" upgrade kit fit my old press? Any answers or advice you can give me would be appreciated. I'd like reload some additional calibers in addition to the 38/357 & 9mm setups that my brother had. Thanks I appreciate your help. elh

Newbie to Dillon Reloading Gear here. I've been reloading for about 25 years on a RCBS Rock Chucker press. My brother passed away recently and I inherited his 1988 RL550 press. It's been sitting in a box in his garage for about 10-12 years, and I'd like to put it to use again. What features does the 550B have that the old 550 does not? Will current Dillon tool heads, conversion kits, powder measures, etc. fit this older press? What is this low primer sensor (electronic) all about? Is it an upgrade? can it be retrofitted to an older RL550? Same questions as above for the low powder sensor? Will Brian's "As It Should Be" upgrade kit fit this older press? Any answers, help or suggestions you can give me would be appreciated. Thanks
