Hello Dave,
i realize lately you need to use what you have on hand. Varget seems a bit slow on burn rate for the 6.5 Grendel so I can see that you would have to fill the case. I was running into powder compression problems with CFE223 and Barnes 100gr. TTSX myself.
Do you have any H4895 handy? this is a bit faster burning powder, also has a very low temp coefficient. If you have some H4895, give that a try rather than Varget. Consult reloading manuals of course but the max charge weights for H4895 are going to be less than Varget so you might have enough room left in the case to avoid severe powder compression.
Varget is on the slower end of the burning rate range for the 6.5 Gr so will fill up the case more than powders that have a bit faster burn rate.
for example my next range test with the 130gr. ELDM is 26.5gr. of H4895.
Alliant Pro Power Varmint and CFE223 would also work for the 130 gr. class target bullets I would think. I've also got some 130gr. ELDM loads to test with 28.5gr. of Alliant Pro Power Varmint and 31.7gr. of CFE223 with the same 130gr. ELDM.
I've wanted to try the 130gr. TMK but so far haven't been able to find any to buy so I cannot say that I wouldn't also have problems with the 130gr. Sierra TMK either. However as you can see with the test loads that I have yet to try, the H4895 load is the least amount so should leave more room in the case for that 130gr. Sierra TMK.
