Primers,

[Kurt]

Curiocity got the best out of me again.

It's been very quiet on this site since Jim left us so I will post some of my why does or does not work.
There are a lot of primer mentioned and mostly Br2 and pistol primers for black powder and the LR Mag primers have lost favor over the last 20-25 years.
Since last fall I been locked in here at home because of the sawbones have their claws in me so to settle my curiosity I did a bunch of 5 shot ladder loads of all the primer brands I have on hand from zero compression to max and the best group for each brand of primers I loaded 10 rounds and shot again to find the best group.

Yes I sent a lot of lead down range but it served several things for me
The primers tested:
Fed LP 150,
Fed GM150M LP,
Fed GM210M,
Rem 2-1/2 LP,
CCI 200 LR,
Wolf Performance LP,
Winchester LR, Fed 215 LR Mag,
Lellier&Bellot LR.
I used the .38-50 Hep and I only shot 135 yard range here at home on and off to get the best sight picture and condition free errors and I used the same powder and bullets the only difference was the powder loads that shot the best ladder loads with the primer used. The interesting thing they all shot very close except the Winchester LR primer loads and the L&B. Even the Fed 215 Mag primer did not go over 2-3/4"
Out of all those different primers the best was the Wolf LR and the Fed GM 210GM.
