    I am having a problen seating 209A federal primers into remington Nitro's.
    I was loading fed gold metal and top guns and had no problems, my loader is a mec 761R progressive,the federal seated flush, but the nitros stuck up a little.i can take a streight edge over the bottom and it will catch,i put in a new primer seat and adjusted seat tube on the press but that didnt seam to make a diffrents,

    i shoot a 870 so i not to worried about shooting them in it ,,but i also was loading them up for my daughter who shoots a 390 Beretta,and with the bolt slaming shut i am concered with that.you just never no how much is to much,

    Has any one else had this problem with the Federal 209A

    My STS do the same thing however I am using Cheddites. I did increase the spring tension on my MEC9000H, but that did not help. I think what the issues is the shelf of the STS is shallower than the Federals or AA's, thus causing the primer to not completely seat flush. WIN209 had the same problem.

    I continue to reload and shoot them with out any problems.

    They'll go flush in the crimp station, and those hulls will take those primers fine after that.

    Mrskeet410, maybe I am missing something ,but my MEC has the crimp station and it does seat all the way. What are you doing differently?

    Terry, It's because of the shape of the Rem primer pocket is unfriendly to non Rem primers.

    STS/Nitro hulls are made for the Rem 209P/STS primers that are a little shorter than most other primers. Sometimes there is a bit of plastic that curls over the primer hole in the hull. A #1 drill bit or 7/32 or 15/64 bit will remove the plastic.

    I use a Mec 9000G and load Rio primers in my Remington hulls. I had to lower the primer seat just a tad and it works fine.

    I've used Federal, Rio, Winchester, Remington, Fiocchi, Wolf, and Cheddites primers in STS and Nitro hulls without any seating issues from either my 9000G or 9000H.
    I'd suggest On progressive reloaders, lower the powder, or reprime tube, slightly.

    I put a little washer in the bottom of the hole the primer sits in while being seated. It fixed the problem. HMB

    Not an issue on a Hornady/Pacfic with a Spring Loaded Primer Seater. I haven't found a primer or hull it won't seat completly and no adjustment needed when switching components.

    Not that it helps your problem, Just Say'n................. :)

    Terry, I'm not familiar with a 761R, but i've had a 600jr sizing die loosen up and it would hit the base of the press before the primer was seated completely. hope this helps. George

    grntitan, I like the holes you have drilled in the primer tube of your 366 so you can see how low you are getting. Took me a while to figure that out. Mike

    Mike,

    Thank you but i can't take credit for the idea. I can't remember who it was, but i stole the idea from someone here on TS.COM. Works great though. Just a glance is all it takes. Sure is better than having powder run down your leg from not having a primer.
