Im wanting to get a mold for 300bo heavy subsonics. Some where in the ballpark of 220+ grains is the norm. Im wondering if the Lee TL 309-230-5R or the NOE 311-247-fn. The lee is a boat tail design, the NOE is a flat base that can be had plain base or gas check based.

Ill be running these through a 10.5" 1:8 twist barrel and Im just wondering if one will be better for accuracy.

Please dont turn this into a "which is the better mold" discussion. My goal is for a better performing bullet.
