I just finished a batch of Varget in a Win M70 chambered in 6BRAi and a 8 twist Kreiger with some miles on it. 30" barrel has been set back once by Northridge and its a shooter.
Good friend let me borrow this rifle and eventually sold me it and two lots of Lapua brass.
I had been shooting (stealing more like it) Berger 105 hybrids and loading those Lapua brass with H4895. Known loads and going MR to LR with some success. Sling shooter as its in a Anshutz stock.
As I got it now, I am loading that same brass with SMK107' Using his known Varget load for a SMK107 30.1 gr Varget
I had to go up to 31.0 grains to reach the same mild velocity of 2848 fps in the same brass. Both he and I run a CCI 450.
This brass is about 5 and now 6th firing and I have been to two matches this year. Xero data is solid with low SD/ES.2850, SD 7.4 ES 12-14
My questions are, is Varget lot to lot different? And would more firing make a difference on the brass? I doubt that! but I am using a LE Wilson Die not Whidden.
Chamber is a .272 no turn. Like I said his known load and his Varget seems to be faster than what my lot of Varget was.
Next question for anyone familiar with the Varget and the SW Precision.
Should I start low at 29.8 - 30.1 gr of SW Precision or would one think as I am using 31.0 gr Varget now would you just roll up 5 rounds at 31.0 SW Precision and test it? I think I know the answer, but I guess i am looking to some insight from those with experience of this same conundrum.
This rifle again is 6BRAi not a straight BR and the SW load dates max for a BR is
Thanks in advance and sorry about beating this horse more.
