Although I don't see any Alliant Red Dot currently available on-line I do see both Ballistic Products and Precision Reloading have Alliant Promo in stock. Promo is essentially the same as Red Dot, they advertise it can have variations from lot to lot meaning you need to weigh a charge or two from each bottle or lot to be sure you are getting the desired number of grains. 19 grains of Promo or Red Dot will deliver the same velocity and pressure but each may require a different bushing. FWIW I have never encountered that in my own use and the bushing that delivered close to 19 grains of Red Dot delivered the same weight of Promo.

Thanks! I did not realize that about Promo and Red Dot. Good to know. Looking into now.

That is good advice about measuring the loads. I do not use bushings for my competition and "old gun" loads. I powder drop and measure each charge. Takes much longer but I guess that's the engineer in me (and once had a squib load in a tournament...). Thanks!

You may want to double check the chamber length. 2 5/8" was standard early on. Then someone may have lengthened them to to 2 7/8".
