Anybody using Winchester 777 primers?
I had read that some people felt that traditional shotgun primers may be too powerful and actually get the bullet moving before the powder fully ignites so I switched to the 777 primers. I don't see too many people here talking about primers, maybe that is because they don't really matter? So I thought I would ask, for Pyrodex pellets, does it matter what primer I use? Has anyone noticed a difference in accuracy between types of primers?

I sometimes use the T7 Primers with Pyro Pellets and they work fine. Now I cant find the chart that Sabotloader sent Me but there is a big difference in Primers as to there Length and Velocity, mabey He'll see this and Post it.

I remember reading a post by Sabotloader where he showed different group sizes with the same load and varying primers, and the differences were negligible. I don't remember if he chronographed them or not, but the groups were very similar and POI did not shift all that much.

Different POI when switching primers... I would say anytime you switch any component it might switch POI, but I my case I have not found changing primers with a proven accurate load has made a BIG difference...
Here is a target that I was testing primarily to see if the amount of velocity would change if I used different primers. It was not really shot for accuracy but you can see the differences...
