Mid range 6br powders and bullets?

Hello all,
New to the forum, and new to f-class. I started off with a factory hunting rifle and stepped up to a semi custom savage I put together myself. It has a t&t SSS target action, 24" Mcgowen barrel, SSS LVT stock, chambered in 6br.
I have been working on loads for this rifle and had fairly good results with 30.4,30.5 Varget and 107SMK's.
I will be trying out some 105VLD's and 95SMK's for the 300 yard line.
My question is what bullets and powders are you folks using for 3-5-600?
I will be shooting in 75 to 95 degree temps in the course of the day. Is Varget a better choice, due to it's temp stability, or should I give a look to rl-15 for the better velocity? What about rl-17 for the heavier projectiles?(got some decent groupings with this powder, albeit limited experimentation)
Thanks for the input.

OK, I'll make a ripple. If you are always shooting at 75-95 degrees RL-15 may not be a problem(?), I haven't used it. I shoot from 40-90 degrees and like Varget. Benchmark may be a consideration or IMR 8208 XBR. I'm just getting used to IMR 8208 XBR; I tried it with 70 gr bullets and it wasn't very good, but it came in to it's own with 87 gr bullets, heavier I don't know (maximum for my 1:10 twist). If you are shooting under a fairly stable temperature range a ball powder may work for you also. No heavier load data, but W748 works well above 70 degrees with 87 gr bullets. No load data for Ramshot TAC, but that may work also. - nhk
 
I have been thinking of giving 8208 XBR a try too, but I have heard that it doesn't work well with the 105 to 108's.(?)
 
Next trip to the range I am gonna work on some promising RL-15 loads with the 107's. I'm just wondering if the accuracy is much better will the temp sensitivity undo the benefit.
 
IMR 8208 XBR

Any one have any luck with this powder in 95SMK's, 105VLD's, or 107SMK's??

Any other recommendations for good consisant loads that will shoot good all day from the fouled hot barrel??
 
I have a 34" Broughton 1in8 in 6BR, I use 8208XBR with 108 Bergers and 107 Sierras and it works great for me. I am getting 3075 fps and 1/4" groups at 100 with the 107s and 2975 fps 1/4" with the 108s.
I am using 31gr with the 108s and 31.5 with the 107s(both are hot loads so I would recomend working up from 29.5-30gr) .012-.014 off jam works well with this barrel. I know quite a few long range Benchrest shooters have been having good luck with the 6BR and heavy bullets.
