Questions & Answers
I have a similar old Lyman Lube/ sizer and a lot of dies bought sometime in the 60s. Will the old style dies fit the new sizer? Thanks Expert Answer

The Lyman 4500 Lube Sizer might work with your older dies. However, I recommend contacting Lyman to confirm compatibility with your specific dies.

Is there another SKU for the unit with BOTH heater, And Gas Check Seater?

No but definitely buy the model with the heater. It saves you a ton of $$. If bought separately the lube heater is between $50-$70. The gas check seater isn't really required to seat gas checks. It can be done without it just with die piston adjustment itself. However the gas check seater is available to buy on the actual Lyman website if you feel you want it. It's not too expensive and costs much, much less than buying the heater separately. I've seated thousands and thousands of gas checks without the "gas check seater" accessory.

Quick & easy by Legacy Reviewer, May 21, 2013
There is a youtube video that I found that really made the alignment of the locking screw for the die a breeze to set up. Lower the handle, after inserting the die and putting the screw on top, just to the point of meeting. This will align the scre...

It's a good machine by Legacy Reviewer, Verified Owner, May 29, 2011
I was sizing 9 mm hollow points from a M-P Molds mold in it and discovered that the extractor was not pushing the bullet all the way out enough for me to get a hold of it. I put a shim in the u shaped part at the bottom so it would push the extractor...

Lyman 4500 Lube Sizer by Legacy Reviewer, Verified Owner, April 27, 2011
After heating the harder lubes this is a fantastic unit. My only issue is the return push rod is about 1/8 of an inch short so if you are doing short bullets you need to put something between the rod ad the lower loop bracket. I called Lyman and they...
