If ya believe all you read I must be the luckiest man alive ....as far as moulds go anyway . In 30 or so , some stayed some went , I've had 1 that wouldn't shoot that wasn't what it could have been . I'd forgotten about the 2 RB moulds bought yr apart .....dang it .....it wasn't that they were under size but that the tangical cut off was too short . Not a big deal if I'd wanted them for 0000B but not cool in a 36 cal 1858 . If the sprue weren't dead up or down it left a gap .
I guess that's about 1-10 but I was just counting as I was typing and through gifting , swapping and buying it's probably north of 40 moulds .
If I had 40 Lyman/Ideal moulds , I only have maybe 20, 1 casts undersized , which I knew when I bought it , and 1 isn't even in the same subdivision with what it is advertised to be . It should be a 250 gr RNFP HB for the old BP Colts instead it's a 285 Minnie and the only thing flat on the nose is the sprue cut .
I have 9 NOEs one hacked on before it came to me . 1 of which I have had to do a bunch of fidgeting with , prue plate mostly , and it wasn't the hacked on mould . 2 of them are exactly what they are supposed to be but I can't use them in what I bought them for because the zero miles bbls are still to tight .
I have 1 M-P , brass no less , it's marked 462-420 . Now I could cry foul on it as under size and weight as it only drops a 460-414 and the HB that was supposed to be 400 is only 380 . However I learned that this was an over run from a group buy and half of the buy was speced for 460-4- whatever it came out.
RCBS I have 6-7 . The 7mm 168 sizes nicely for a 270 and needs only seat .020 short of the top of the top band . The nose is only .273 , sloppy even in new 7mm bbl at .277×,284 .
Based on this M-P has a 100% fail rate plus 3 GB that I backed out of over a yr after adding my name to a yr old list .
Lyman can only manage 80% useable moulds at best .
It looks like in my sample RCBS at best only pulls about 87.5% .
Using those stats Lee looks like a way better roll of the dice .
Mountain Moulds is the only maker that has delivered a perfect mould under budget , and under time . LBT did a good one also but the very similar Lee 6C cuts casting time by 2/3 by count and shoots just as well in the heavy bedroom gun .
Like M-P however a sample of 1 isn't really a fair shake .
Cramer is one that the sample of one really lived up to the hype . The Herters makes good bullets also , sort of a hype man selling unbranded seconds in new packaging . Lee but with more colorful hype .
I'm not saying Lee is the creams cream , but anybody can get a bum product . Did anyone read that thread over there about the 1895 Remlin ? How do you get 4 bad bbls ? What are odds ? Especially when at least 2 of them were factory rebbls ?
Luck of the draw in mass production where the line is inspected at 25% ,50% at best .
