I have been reloading since the 70s and still do with my LEE and RCBS dies that I have had since then. I use an old LYMAN SPARAN single stage press that I have had since the 70s. The only thing I have added since then is a small digital scale for weighing powder charges. All my loads are weighed to 0.01 grains + -. I hunt with a 308 heavy barreled HOWA mountain rifle and have never missed! You don't need any of these new fangled multi station presses to produce perfect loads. I reload 308, 35 Remington, 38 and 357 Magnum as well as 45 ACP. I aint broke nothing yet and am still using all the same equiptment!!!
I've had similar experiences. I still have and still use my old stuff.
But the irony of what you have done might well be that "the only thing you have added since then" might not be the improvement that you think it is.......
There is no doubt that digital scales are more convenient, but they usually lie. Just because the digital readout says that you are +/- 0.01 grains, doesn't mean that you really are.
I have yet to buy or use even one digital scale that is more reliable than an old fashioned balance scale.
Try weighing a charge and then add just granule of a large size powder (like 4198 through 4831). One granule of powder is significantly more than 0.01gr. Yet ill bet the scale doesn't move more than once in a good many tries.
Or try weighing just one granule alone.
Or try re-weighing the same charge several times.
The bottom line here is that the fancy digital readout can't be any better than the cheap analog weighing system and sensor inside the scale.
I do not trust digital scales and only use a digital scale to pre-weigh charges and sort brass. Then I use an old fashioned balance beam scale to fine tune the charge.
For the benefit of any one else reading this, my advice is not to trust a 0.1 grain digital scale either. They are no better. An old fashioned balance beam scale will almost always throw better charges than their new fangled digital equivalent.
