RN vs FP for accuracy

Hey all,
Ive been searching this forum but cant find what I'm looking for.
I've always loaded some type of HP's in my .40 and .44 mag. for plinking/ practice. (Black Talons for home defence/ CCW.)
Anyway, I just recently became a member of Frontsight in Nevada and they require factory FMJ's when shooting at their ranges. I would like to duplicate a factory load with my reloads but before I do I was wondering if there is any noticable difference in the accuracy of FN vs RN slugs.

I've also had a terrible time finding bulk 155gr FMJ's of any kind at a reasonable price. I did finally find this:
But id be interested to know of any other similar suppliers.

I am also interested in .40 cal accuracy loads for other competitions where I can shoot ANY bullet I like. I've narrowed my powder down to 231, bullseye, and AA#5. The goal is to have an accurate round with minimal recoil to stay on target. I currently shoot a Glock 23 and Baretta 96F.

Thinking about getting a 1911 in .45 for these matches also.
Thanks for any help/ tips,

The squareness and precision with the base of a bullet will have a far greater effect on accuracy than weather or not the bullet has a flat or round nose shape
From what Ive read the hollow base isnt meant to expand to fill the chamber but to make the bullet longer. Essentialy making a 155gr .40 bullet the same length as the 180gr.

Thanks for allyour input Marshal

Marshall has it correct about the hollow base
First of for a spin stabilized bullet the more weight in the rear of the nullet the better, this is an undisputable fact. Secound yes a hollow based bullet will obturate with less pressure than a flat based. The smart money says that the Berry bullet do indeed obturate.

The marketing BS is interesting, but none this is new, it has all been tried before
