Tim length for 30/30cases?

[jjrothWA]

Have some once-fired 30/30 bras (various manufacturers), Sierra indicated the 2.039" is maximum.
Measured the lot and four are 2.033, some at 2.035" and majority are 2.038", after resizing.

Use the 2.033 or 2.030"?

Will be used for a T/C 21" 30/30 barrel, so the initial load will be the 110gr MC for fire-forming the case then neck-size for loading 165gr Sierra HP or SPBT for deer and black bear.

The T/C barrels seem to like tight-head space for best accuracy.

Thanks and MERRY CHRISTMAS to ALL.

The max length is 2.038 - 2.040. Check the Sierra manual, your trim to length should be 2.029, so you can pick whatever the T/C likes best in that range.
