Two brand new Starline cases. Look at the primers and tell me which one has the CCI-200 rifle primer and which one has the CCI-300 large pistol primer. Maybe neither, but tell me which one is more likely to have troubles in a rifle mag tube or get locked up in a revolver.
CCI-200 Rifle Primer = .1275" Length
CCI-300 Large Pistol = .1205" Length

My measurement of my newly purchased Starline brass' primer pocket.
Measurment from the outside wall where the primer seats is .1235" deep (Photo)
CCI-200 Rifle Primer = .1275" Length
CCI-300 Large Pistol = .1205" Length
Remington 1 1/2 Primer = .1215 Length
Winchester WLP = .1195" Length
Starline = .1235" Deep
RP Brass = .119" Deep
Winchester = .119" Deep
If using my batch of CCI-300 pistol primers with my batch of Winchester or RP brass, you might get a primer extruding .0015" past the case rim.
If using my batch of CCI-200 rifle primers with my batch of Starline brass, you might get a primer extruding .004" past the case rim.
If using my batch of CCI-200 rifle primers with my batch of Winchester or RP brass, you might get a primer extruding .0085" past the case rim.
Just for kicks, my 45-70 Starline pockets are .131" thus using the CCI-200 rifle primers would result in a .0035" recess rather than any kind of extrusion.
Yes, all cases photoed are brand new 44-40 cases Doesn't mean other primers are as long
