Full Length Sizing Dies
Excellent dies 18/06/2017
I use the .308 NM dies for an AR10t, and FN-FAL, and a DPMS Recon. I pretty much only use Lake City once fired brass that has been shot out of machine guns. I have had zero problems with these dies. I have had no issues. I bought a SAAMI min spec chamber gage and the NM die wouldn't size them enough to fit the gage although the loaded rounds still fit MY rifles. I believe this is because of a generous machine gun chamber. So I bought the Forster small base die (which I also give 5 stars to) so I could size this brass down a little more at the base and now all the cases fit the JPE SAAMI min Spec chamber gage as well. I believe I will be small base sizing these cases the first time I resize them from now on, not because I have had issues, but because it seems like a good idea to me. I seat all my .308 bullets with a Forster micrometer seater die which I also give five stars to. My run out, measured with a Hornady concentricity gage, is typically between less than .001" to .001" and my groups in all three of the aforementioned rifles are sub-MOA. The Forster dies are notorious for low run out. I have a Redding micrometer seater die for 300 win mag. It's good but all of my Forster micrometer seater dies are better. They are easier to adjust and read and you can use compressed loads with them unlike the Redding die which is a big problem IMHO. I have just ordered the Forster full length resizing die for 300 win mag to compliment my Forster Bushing neck sizing/shoulder bump die. I am perfectly happy to use nothing but Forster dies. They have never been anything but 5 stars for me.
Cases won't chamber 11/09/2016
I resized about 50 cases with the Forster National Match die and seated them with a Redding seating die. I didn't check them with my Wilson gauge and at the range discovered that almost all of them would not chamber in an AR-10 built with a Krieger barrel. When I checked them with a Wilson gauge they would not fit with the base sticking out of the bottom of the gauge. I tried resizing them again by overcamming in a Forster Coaxial Press and they were still too long. I tried the same case in a Redding bushing die and they were fine - even a little short as I adjusted to also overcam. With the Redding I have the option of bumping the shoulder less but the Forster makes them too long. I could have machined the bottom of the Forster die to bump the shoulder back but I should not have to do this. I have never had any problems with any Redding dies. I have no faith in the Forster dies although the Coaxial press is unequaled. I bought the 300 Win Mag National Match die also but I also returned it. With that much powder in the case I don't want to second guess. Will stick with Redding only.
