Getting ready to order a new mold for my 45 colt addiction. I have plenty of molds and want one more to fill a perceived need. I have a 255 RNFP SAECO mold that does great service but want a LBT Long Flat Nose mold for my soon to arrive Freedom Arms 97. The 97 has short cylinders, so I can not use my other molds with out crimping over the front drive band.

Mold will be a 260 grn LFNGC with a short nose of .325 to fit the FA97. It might see limited duty in a Marlin 1894 also.

How many holes should I get? 2 or 4.

Get as many cavities as Veral will cut!

The more you shoot it the more cavities you want. Most of my molds are four cavity.

This particular mold will not get used or shot a lot as the RNFP will be my main plinker. It is the only mold with a short enough nose length and is a 4 cavity. it sees considerable use in my other 45's also.

I have a LBT 4 hole 285 LFN GC, as well as a RCBS 250 KT 2 hole in addition to the 4 hole Saeco 255 RNFP.
For a light weight I have a LBT 225 LNFP 4 hole.

I am leaning 2 cavity because of price and the limited amount this boolit will be shot.

You can always cast fewer bullets in a sitting, but it's a lot more effort to cast a lot more in a sitting because you've discovered you like a bullet design better than you thought you would.

I'd go with the 2 C.

4 cavity, no question. The sprue is going to take the same time to cool, and is the bottleneck in the process. I'd rather wait on 4 slugs than 2.
