Blemished bullets are far superior to “seconds”.
I bought several hundred seconds from an Australian company many years ago, still have some actually, they are a .25 cal 75gr HP that shot very well to start with, then no holes on target at all.
Had a mate spot for me, on several shots, he could see the bullets tumbling with the sun glinting off them, other occasions there was a blue streak about 30yrds out then a big ‘puff’ of blue/grey another 20yrds or so out.
The meplats and ogives varied so much with these bullets that I just set the seating die and seated them all to that position regardless of the actual length seeing as the mag box had heaps of room. The first batch shot quite well, the second not so good, the third batch was the blowing up batch and the rest of the bags shot around MoA at 100, good enough for taking foxes etc.
I had 10 bags of 250 bullets in total, I bought them in batches of total weight, not bullet number. The only bag that blew up was the third bag and the ogive lengths were all over the place.
The other thing I noticed with these bullets was the depth of the hollow point cavity varied by more than .100” in most batches, although the weights were very close to 75gr. The cavities were also ‘caked’ with some sort of solid lube-like substance to varying degrees, some full some partially and some with very little.
I was shooting these out of my 25-06 at just a smidge over 3700fps,
I contacted the guy that made them and he said that there were 2 problems with the jackets, firstly, the jackets had drawn thinner on one side, and the meplats and ogives were vastly different due to this, which I already figured out. He also said the slug of lead may or may not have huge voids in it due to the thinner jacket. I think I found this out when the bullets were tearing apart in flight.
He said it was the first run with new tooling and he didn’t want to go the expense of removing the lead and then melting the jackets or lead for re-use.
I will buy blemished bullets, have several dozen boxes of Nosler blems in BT, AB and PT, all shoot just like the shiny one’s do.
I will never buy seconds again, sure, they were cheap, but they were NASTY too.
Cheers.
