Pretty sure that 068 is their copy of the H&G 68BB.
The Saeco 069 is a plain base copy rather than beveled base.
The Saeco 451 is supposed to be a copy of the Lyman 452460, which in turn was a copy of the H&G 78 designed by Ed Rowland.
I have read though that the 451 may have a shorter nose than the 452460.
Not sure on that as I have never seen one in person.
The Saeco 130 is a copy of the H&G 130.
That bullet was also copied by Lyman and sold as the 452488.
Back in the '50's (or "60"s?) the H&G 130 became the most popular bullet with the Bullseye shooters of the day.
According to the NRA reprint I have, the traditional load for 25 yard work with the H&G 130 was 3.5 grains of Bullseye.
Most would up the charge to around 4.2 grains for 50 yard work.
You have 2 very good molds for the 45 ACP and maybe 3 if that #451 is a faithful copy of the Lyman 452460.
Two most critical things to watch when loading these is the amount of taper crimp applied and what magazine type(s) you use.
The 130 should like the early release/parallel lip style which is what most mags sold today are.
The others though will
probably prefer a hybrid or GI style magazine.
Here are links to 4 old posts here that are absolute gems with regards to loading the 45 ACP and getting a 1911 to run
reliably.
