Re: 308 Winchester Varget 165 grain hpbt powder charge contradiction
It's not a contradiction, and neither manual is "wrong." In fact, I'll assure you, both are perfectly correct. They're just different. The were developed in two diferent labs, by different operators, using different rifles, different lots of the "same" components, etc.. I've always tried to get across the concept that a reloading manual is nothing more than a report. You'll understand them better (and use them more safely) if you take them as a write up saying, "we tried this combination, and this was what we saw in our rifle. Your's will vary, so start low and work up." This is precisely why virtually all of them are so adamant in starting with the bottom load shown and working up carefully, as pressure signs in your rifle will allow.
You need to verify that you are indeed using a tight neck chamber before you do any reloading for the rifle. A quick trip to the gunsmith for a chamber cast will answer that question, and give you the chamber dimensions you need to know to reload for this rifle safely. Do this first, then worry about charge weights.
