I do not trust anyone to do loads for me. I made a mistake once and had my brother do some loading for me with my equipment and supplies. That was many years ago. He is quite a bit younger than me and he was staying the night, was bored, so I thought I would keep him busy in some thing he liked. He has the attention span of a gnat and forgot to charge a 44 mag. The primer was enough to get it into the bore, there it stuck. I had a devil of a time getting it out. Never again, I do not trust anyone, not even family. Loading cartridges is satisfying to me and relaxing. I can come home from work all keyed up. I set down at my bench and figure out what I want to do for the evening, get out my equipment and supplies. By this time work is all but forgotten and I can concentrate on the task at hand. I started out using Lee reloading kits. The kind you pound on, I had no press. I had one for 22 Hornets and added one for the 222 Remington. I soon found out that I wanted to maximize my time better. I bought a new RCBS Rock Chucker, new RCBS dies for the Hornet and 222, a couple of manuals. I also bought a used RCBS 505 scale and soon after a used RCBS powder thrower. If you noticed a RCBS theme here you are correct. I did not know dittily about reloading and the guy that I relied on told me that the only thing to get was RCBS. I have been adding ever since, but I have branched out and now have dies from every major maker of them. The original press is still being used along with some other equipment I started with. If I had it to do over I would buy a relaoding kit in a box. It will come with most every thing you will need. As has been said before, pick your color, just make sure the press is cast iron, it will last you a life time. While all kits come with a press, the rest of the equipment varies from kit to kit. Some do not have the best scale. You will definitely want a good beam scale to start with. Some kits come with good ones and some don't. If it doesn't you will find out quick enough. Make sure you get at least two major bullet company manuals, more is better. As far as the dies are concerned, you will have to buy those separately. Just start out with a "full" set for each caliber. I have added specialty dies later for certain applications, but the full sets will get you started for sure. Hopefully you have some once fired brass for each of your rifles, so you will only need to buy primers, powder and bullets for supplies. Start with the bullet. Choose a bullet for the application you intend it for and the twist rate of your rifle, buy them in the smallest quantity you can (usually 100, but some times 50). I usually start with good, cheaper bullets, like Remington Core-lokt for your 270 and Hornady v-max for your 223. If they shoot good, you have it made, if not then you can try other style bullets. Then choose a likely powder based on the information in the loading manuals you bought to match the bullets you purchased. I try to find a powder that gets the the most or near the most velocity with out going over pressure limits. It is a good place to start, but it does not guarantee anything. It is just somewhere to start. Buy just 1 pound. Based on the manuals and powder you are using pick a primer, again just buy 1 tray. Now put together your loads working up from the lowest recommended powder charge to the highest. If you can just load 5 at a time while working up. Sight in your scope as you develop the load. Run them over a chronograph at the same time. Maximize your investment in bullets, powder and primers. When you find the magic combination, you have your load. If you can not find a good load start over with another powder, unless your groups are really large, I would recommend another bullet to try, powder is not going to make big differences in group size, generally. I am trying to get you into a load with the least amount of money invested. Once you find the right load, then you can buy supplies in larger quantities. Hopefully you will find it quickly, but some times it takes several combinations to find the magic. I am just giving things to think about here. Your path is wide open and you can take it any way you want - but pay attention tot he data in the loading manuals and read their front sections on how to load before starting or getting your supplies. There is some good information right at the top of this page, read that too. Good Luck and Good Shooting.
