Thanks. I'm slowly learning.

To review:

Bullet is 160 g Woodleigh Protected Point.

Brass was once-fired Norma and RWS.

Powder was VV N160.

Primer was Federal Match

Cases were neck sized, not full length sized. I did think perhaps I pushed the neck back too far, which is why I bought the case gauge. On my second load (reduced even farther, and with the RWS brass), I "smoke checked" the brass, and believe it was OK. Now I have the case gauge in hand, and can actually measure.

I used the taper crimp because with the spire point of the PP, I wanted to ensure that I would not push the bullet into the case when feeding. To be clear: when testing the load, I hand fed the round into the chamber, so I'm sure I did not push the bullet in during test firing.

Cases were trimmed to length before I sized them, and re-measured after.

I will check neck diameter once I have new once fired cases.

I'm away from home right now, but will probably play more this weekend.
