I didn't want to order them and pay a hazmat fee. I'm off work the next 2 days for the last 2 days of gun season here in Maryland so maybe I can get to the range next Tuesday and give them a try.
Just so you know... you really do not need a Mag primer to shoot BH in most cases. It is more dependent on your breech plug and the headspace of your rifle. Western recommends the Mag primers as BH is so hard to get ignited in some rifles and to get it done Western says use Mags.
I really do not like Mag primers they can create other problems including pushing the bullet off the powder before full ignition of the powder.
I do not shoot a lot of BH, when I do it for testing purposes most often, it is just to darn expensive for me.
When I do shoot BH I use a plain simple W209. If your gun is right that is really all you need.
I believe that primers will/can effect POI on a target but I have never really proved they had a lot to do with accuracy, if the load and sabot are right for your gun.
Once somewhere a long the line some one said you needed a hot primer to get more velocity from BH. I shot this target one day just to check that. I now wish I had shot it for accuracy also. These powder loads were thrown on site - they were not pre-measured. The gun was not allowed to cool at all it was just one shot after another.
As you look at the range of primers shot in this experiment you will see I even shot some ML primers. The Remington 209-4 primer is the weakest 209 I know of, it was built specifically for the 410 shot gun. Remington does not make it any longer....
