Anybody have expireance with cheddite primers as to pressure and velocity in low pressure loads? I like the way they feed in my mec.

Especially in low pressure they can be subed for Winchester primers as far as power. They are a bit harder and prevent primer drag in some guns.

Vance, I will go along with Mark as a substitute for Winchester primers. I have been using them in all of my reloads that call for Winchester primers.

There are some 12 gauge low pressure load recipes using Cheddite primers on the Hodgdon reloading data center website. I have been shooting skeet with a 7/8 ounce load I found there using Remington Gun Club hulls, Ramshot Competition powder, and Rem TGT 12 wads. Pressure is listed as 5,300 PSI and velocity is 1,150 ft/s. It is a nice clean burning load that does not leave a bunch of unburnt powder and residue in the barrel.

Vance, I agree they work noticeably better in my MEC loaders, too. Not sure how anyone determines a "harder" primer, short of having light strikes or misfires. Over the last several years, I've had more problems with factory ammo than in my entire life! Not any trouble with W-W, Rem., or Cheddite primers in my reloads, though.

Be careful out there. There are some nice published low pressure loads on the Hodgden site however it has been reported from other blogs that it can raise pressure by over 2,000 psi over Winchester primer loads. These are tested loads.
