Hi all,
I was wondering if anyone has noticed if the stated BC on the 80.5gn fullbore bullet has changed in the last few months?
I brought a box about 4 months ago and another box about 3 weeks ago both from different vendors and it says they are 80.5's. the BC on the label is different. there is 0.018" difference in the bearing surface between the two, the longer ones have the higher BC.

Firepower usally means an increased number of misses per minute. 50 misses are not firepower. One hit is firepower

I remember reading somewhere that after comparing various Fullbore bullets Brian Litz reckoned that Lapua's published BC for their 155grainer was overstated by a not inconsiderable margin? No experience with any of these projectiles so apologies for going off on a tangent but maybe the revised BC's are more in line with the real world results over time.

These numbers are theoretical anyways but I can attest that the pill that worked for me at 1200 yds was the 155 berger hybrid, after the 155 sierra 2156 was poor at 1100 yds (and presumably the 155.5 berger fullbore would be like the sierra since they are very similar.) However, I have a 28inch barrel so i am sure with a 30incher and a hotter load you could prove me wrong
Also, the 175gr berger did not do well but i have been told the 175gr sierra holds up better (accuracy) in the transonic range. (ill bet the berger 155 hybrids are going alot faster)
