have you ever wondered why all the warnings about reloading danger from the bullet and powder company's?
Are you one of those reloaders who looks at the book and picks the load one grain below max and loads it. well, i have a brother that does just that as well as a good friend.
the good friend was in search of an early sako extractor just for that reason, it was a 149.00 lesson. his rifles max load is book starting loads, he is one of the guys that's the smartest guy in the room and so is my brother.
For safety reasons i have told both to at least 1 shell with the lowest load listed up to the load they are convinced will be the right load. Chronograph each load up to their chosen load.
here is why, i loaded some 7.62x39 loads for my Cz 527, all the forums were saying they were using 31.0 of cfe bk with a 123 gr sst bullet at 2573 fps.

i loaded 27.5-31.0 and here is the chro results.
27.5 2449
28.0 2473
28.5 2553
29.0 2563
29.5 2593
30.0 pulled
30.5 pulled
31.0 pulled
it should be noted the 29.5 gr load and 27.5 showed the same primer signs (nice round edges) and it took both hands on the priming tool to seat the primer.
Thoughts?
