You can get away, with a friend's initial help, with a minimum of kit. This should be a decent QUALITY set of dies with easy seating adjustment and easy decapping stem adjustment. As they lack the latter I rule out Lee's offerings in that department. Combine this with a good quality, new or secondhand (as long as used and not abused) compound leverage press.
I WOULD NOT RECOMMEND A LEE LOADER UNDER ANY CIRCUMSTANCE UNLESS YOU HAVE AN ARBOR PRESS. AND YOU USE THEM AS IF THEY WERE ARBOR PRESS DIES. REPEATED AND RE-OCCURING HAMMERING OUT CASES FROM IT WITH A STEEL ROD DOES THEM NO GOOD.
I am not a staunch defender of all things Lee but feel the need to rebuff some of this (there is a lot of Anti Lee sentiment and rubbish spouted on the basis that the cheapest products are the worst....comparably that MAY be the case but that does not make them poor or not fit for purpose!)
The stem adjustment on a the Lee dies is no better or worse than the ones on the RCBS dies which are arguably more expensive both new and second hand.
Lee dies work just fine (lets face it if they didnt they wouldn't have been making them for over 50years!)
one thing with them all is you should make sure you can get spares of all the parts of any dies you get and quckly!
decapping pins break (apparently), stems can bend, collars get lost etc etc
The Lee Loader is possibly the most prevalent reloading device in the world....
Sales topping several hundred million...
tapping out a case using the strongest part of the case with a steel pin and a wooden mallet whilst in the hand of the operator is hardly the same stress as a 65,000psi explosion taking place.
I get that the case MAY be supported at the case head by the bolt when fired but do you really believe the shell being tapped out is enough to damage the case?
really?
it is only sizing the neck and the rest of the body is barely in contact with the die
I have stripped off more rims with cases getting stuck in a FL die in a press than I have ever seen damage from a Lee Loader "extraction".
Tell me double sizing a neck and shoulders with a FL die using a rim designed for light load is not more stressful?
I am on 10+ firings on some of my .270 brass, at least 7 of those were "Lee Loads"
don't discount the Lee Loaders if you want cheap and accurate ammo
(and that is cheap INCLUDING THE COST OF SET UP HARDWARE not conveniently discounting the £400 you have sitting on a bench when you do you per round maths!)
you do not need micrometer seating dies, arbour presses, +/-0.001gr scales and a laboratory to make "better than factory" ammo
if you want them all that is fine, but please make your own choice rather than believing what other have chosen to believe.
(BTW I actually use BOTH Lee Loaders and a press. I can load with a press in the living room without being kicked out for being noisy! none of my "press ammo" is more accurate than the "Lee Loader ammo")
