Sendaro,
I realize that you're inquiring about the NOE 311-230FN Black Out bullet . I don't have that mould but I do have this Accurate mould that is similar.
I shot my 240 gr. Accurate .30 cal. plain base at 50 yards.
Rifle was a Tikka, 30-06 Springfield.
Here are the test targets. I shot ( 4 groups with 5 rounds in each group ) Range was 50 yards. ( on the 8.0 gr. load , I had to expend 2 rounds to get the rifle hitting near the bull , therefore , the 8.0 grs. of Unique load only had 3 rounds in the target.)
The bullets were sized .3115 " lubed with Ben's Red and rolled in thinned 45-45-10 and allowed to dry for 2 days.
I did a " ladder test ", shooting 8.0 Alliant Unique with the 240 gr. bullet, 8.5 grs. of the same, 9.0 of the same, and finally 9.5 grs.
As far as I'm concerned it looks like 8.0 of Alliant Unique is the clear winner in the accuracy dept.
I can see some " tipping " on the 8.5 gr. test target, possible a bit of it on the others also. The 9.5 gr. target seems to show less / if any tipping.
It is my opinion that at the velocity that I was shooting these hvy. weight .30 cal. cast bullets at out of my Tikka , 30-06 that my particular bullet is " right on the edge " of what my barrel can stabilize.
