Sounds like you`re trying to start reloading on a budget. For low volume shooting like what it sounds like you are doing then a single stage press.
It takes only one die at a time, and while cheaper to get into isn`t for making a lot of ammo fast. The LEE anniversary kit is a pretty good way to get into reloading. I can`t remember if it has a balance beam scale or not, but it has pretty much every thing else except for the dies. I haven`t looked lately, but I think they still make them.
LEE RGB (really good buy) are good dies for the .303, and I`m not too sure where you would go for .41 Colt dies. Not an `off the shelf item`. The RGB dies are pretty cheap in price, $20-30.
You might be able to order your .41 dies from one of the site sponsors.
I`m not brand specific. I have a bunch of different brands on my bench. Some guys are very brand loyal, others not so much.
You`ll need a manual or two, at least. Minimum of two manuals to double check the loads to make sure that you`re in the safe zone. Although there are the booklets that are a compilation of all the powder and reloading manuals for the more popular calibers. I have one myself for the .303. $5-10 for the booklet, IIRC
Or if you want to buy separately you`ll need a:
Press
dies for each caliber
scale
shell holder for each caliber
powder measure, or the little dipping spoons
your choice of powder
primers
bullets
Hope I didn`t forget anything
