As noted by the Op,, he'd like to own a turret press,, but his CURRENT press is a single stage one.
The best advice is given by maxfam,, as it was also suggested in a different thread. Seat all the bullets & re-adjust the dies to crimp in a separate operation.
And if adjusting dies is an issue,, or as edm1 says; "I hate trying to set them up." then look into getting a separate die for crimping.
I've been loading ammo since about 1977. I have the equipment to load well over 50 different calibers. Adjusting dies is just a small step in the process of enjoyment of making my own ammo. It's not complicated or hard to do. You just have to go slowly,,, and adjust in small amounts until you get to where it needs to be. Many of my dies, once set,, never need re-adjusting,, and others,, depending upon what I'm doing,, I adjust often.
The OP has a Lee single stage set-up. Fine. Expenses are a bit tight,, so he's trying to be as frugal as he can. Fine. Offering info not useful for his equipment,, or whatever,, isn't helping him fix a problem.
Yes,, a better press,, or a turret,, or multiple dies,, or additional dies or whatever is nice to have. But each loader has to look at what they are doing, why they are trying to do it, and be able to afford the things necessary.
There is another reloader,, whom I gifted a Lee "Whack-a-mole" loading kit several months ago. He's very limited on money,, space & equipment. Yet,,, he & I have been enjoying many, many PM's back & forth,, on his attempts at building the best ammo for his purposes with what little equipment he has. I've never forgotten how I started. Very little money,, and with limited equipment. I had to scrap & save to buy a piece of equipment whenever I could. It wasn't easy back then. But over time,, I managed to find stuff, upgrade my equipment, and now,, I have an extensive handloading set-up,, that many would envy. But it took me over 45 years to do it. And I still add stuff as I find something to make a loading job easier when I can.
Reloading is a fun part of the shooting sports for many. To others,, it may seem to be a chore,, or a necessary evil. I often say; "If you don't enjoy it,, they why the heck do it?"
So,, for crow#2,, I applaud you for all your questions in the many posts you've made here. I hope you've been able to re-learn many things from long ago. I hope you are enjoying getting back into it to where you can look at the many responses & choose what YOU feel you NEED,, and can afford. Once you get the basics,, then maybe you may feel you want to upgrade a little & add a piece of equipment,, (such as a separate crimp die) or whatever. No matter what,, as long as you enjoy it,, and it helps you shoot more often,, GO FOR IT!!!
