I just received my copy of Sierra's #6 reloading manual to go with 1 thru 5. Lots of new loads for the new powders. In the handgun section there is data for the 41 Special using the 2 Sierra .41 bullets and Starline brass. Also included is 45 ACP plus P data and data for most rifle calibers but not all. There is even a Legacy rifle section for old but not forgotten calibers. The book is in the big ring binder format and almost needs a table for reading. Hint: catch it on sale at Midway when free shipping is an option. Mine shipped from backorder at the sale price, but no free shipping. Bob!!
