Just bought a Marlin 336W (used but in good shape) and loaded some Lyman 311041 boolits, crimping them at the crimp groove. They would not go into the chamber - I couldn't force the bolt closed. Left 12 nice grooves on the boolit.
In order to chamber them, I had to reduce the cartridge length to 2.420 inches which means that I had to crimp them above the crimping groove - actually at the point on the nose where the size reduces from the diameter of the bands to the nose diameter.
First of all, is crimping the boolit at that point going to be OK?
And second, does this mean that this chamber is too short? Lyman lists the "standard" length for this cartridge at 2.550 inches - a long way from 2.420. As long as the 311041 has been around, I would have expected it to work fine crimped at the crimping groove.
Thanks for your advice.
