of course it makes no damn difference, a press is a press.
I really believe this is the right answer.
The other mental rabbit hole I went down because of this thread is should I try to improve my hand loads? Three pages of notes and a flow chart later and my best internet research says yes. I’ll start another thread on that.
But let me tell you why I believe press doesn’t make a difference. There is an online blog ( Precision rifle blog, what the pros use) where they survey the top 200 pro series shooters. One of the recent surveys was on reloading,( and 97% of the top 200 hand load their own ammo)
If you review the whole survey ( three parts) you see a great deal of agreement on things that matter, and very little agreement on things less critical. Bullets? Pick a caliber and 66-76% Berger, 10-16% Hornady, the rest in the noise ( although Sierra does ok in tactical decision of .223 and 308.). Side note on Hornady bullets- I was surprised to see that not a single competitor in top 200 used the ELD match bullet. The only Hornady bullet used was the A tip.(Aluminum tip)
Brass is pretty much two vendor race.
But other things are all over the place with no agreement. What press used is all over the place. #1 press for resizing was RCBS rock chucker, but only at 20%. Dillon third at 15 or so. All kinds of single stage progressives and arbor presses
Press used for seating bullets had similar results. Rock chucker #1 20% ish, Dillon third. Arbor presses did a little better for seating press
So I’d say press doesn’t matter
Now you want to blow your mind? While press doesn’t seem to matter, there was a great deal of agreement on what they used for sizing dies and seating dies, and I have to say I don’t have any of those brands in my reloading room. The die choice seems to matter more than press choice
