I intend to use this in F-Class with (at this time anyway) 105 Berger Hybrid Targets. My opinion is that this stacks up very well compared to my usual benchmark Lapua. Case Overall Length: Quite consistent at 1.910-1.911 with the occasional 1.912 Neck Thickness (with a ball-micrometer). Some are quite consistent at around 14.7 thou mark, with some showing show variability on individual pieces between 15.0 and 14.4 thou. I am going to neck turn them to approximately 14.5 thou to take out most of the variability. Loaded rounds will work out to around .272 neck dia. (chamber neck dia. of .275) Case Weight: Very good in my opinion, weight was typically 169.5 +/- 0.7 grains The primer hole opening has a greater radius then Lapua. Priming appears to take less force compared to Lapua.
