Working up a load for a 180 gr. round nose cast bullet.
The Lyman's manual shows a 175 gr, flat nose start 4.3 max 5.8.
Should I just use this data, or should I go slightly below?
Also loading Berry's 180 gr. rs I've been previously told that Berry's are very similar to speer tmj (so I bought a speer manual) It doesn't list 231 for the 180 gr., but does for the 165 gr. 5.8 start 6.3 max.
Judging by the other powders listed and the difference between 165-180 gr., it seems I should go .3-.5 lower for the 180's.
starts listed:
There is also a HUGE discrepancy between Lyman and Speer manuals:
For the Speer 165 gr. TMJ part#4410 Lyman's lists the start load at 5.2 and the max 5.8 while Speer lists the start at 5.8 and the max at 6.3.
This trend holds true for other powders as well.unique is 5.4-6.0 in Lymans while the speer lists 6.2-7.2
Thanks,
