The HBC is of excellent quality. Having loaded many 1000's I found less that 1.5 thou variation in dimensions that matter with around 0.5 gn variation in weight, which is of little or no consequence.
There is some ( up to 10 thou ) variation in ogive to base dimension from batch to batch, but again of little consequence and heaps better that Berger which I have measures at 55 thou variation base to ogive batch to batch ( a real PITA )
I have shot these HBC's in 3 groove 14 twist barrels and they give excellent results at least up to 600 yards. I Have not shot them beyond this distance in the 14 twist barrels )
Have shot both pointed and unpointed -- no difference. My personal preference is for unpointed.
Only wish that David would produce a tangent ogive 155 grainer -- would'nt have to buy from overseas then.

Happy to be corrected, however as I said there is a fair bit of anecdotal evidence (that no, I havent bothered collating due to it being anecdotal) that points to QC being marginal at times.

Oh and yes, I still use the Dyer HBC its reasonably priced and Aussie made.

Anecdotal evidence is not worth the paper it's not written on and requires taking with a grain of salt.
If I had to fault any aspect of the HBC it would be the Base to ogive dimension, which to my way of thinking is a little too long, resulting in a more than necessary amount of the projectile within the case thereby restricting case capacity. Now, that is with a chamber to say B150 dimensions. This can be overcome by using a longer throated chamber like an M852, But that creates a problem if a change is made to say a Berger 155.5 which can have a base to ogive measurement of up to 80 thou less than the HBC. resulting in about 65 thou of parallel locating in the case neck. OK but barely.

Barry can I pick your brains a little? Do you shoot the HBC bullets into or off the lands for best results?

G'day Phil.
