Yes, the 1010 poise is different, same as my late 80s RCBS 510, but the scale bases are essentially the same. Some like the slide, some like the dial, they both work.Isn't the single grain/0.10 grain adjustments quite a bit different? I have an RCBS 1010 and don't really care for the adjustment. If you are close to another 10 grain adjustment, say at 59 and going to 60 you have to spin the adjustment a long way. The 505 is a whole lot faster and easier to adjust. I can't speak to accuracy of them.
Scales in my prior post were manufactured in 1974 for the 1010 and 1970 for the 505 and I have the original manuals and boxes as well.
