85gr Sierra load help

You should find a node around 31.0 - 31.5 with XBR using a Lapua case and an M primer. You'd have to vary the charge with Hornady and others. Alex-A 16" Avg. vel 2726fps@ 31.5.

Standard disclaimer goes: work your way up carefully because YMMV.

I would just use Hodgdon's data for 90s as a reference. They list all of the four powders they use for 85s for 90s, with starting loads for 85s a half grain higher than 90s and with all of the 90s having a higher max charge. I would look to start 1/2 grain higher than the 90 XBR data and use the 90 max for the first run through.

My load is 32 gr H335 at 2960fps .

I haven't put it on my old phone Sierra's data is now available free on their phone app. I do not know what data they have for the 6.5 Grendel https://download.cnet.com/Sierra-Bul...-78146268.html

I will probably be using SW Match with the 85gr or TAC. I will update with results if I find a good load to use.

29 gr of AA2200 have my Sierra 85 doing 2810 fps out of a 16" barrel just getting dialed. according to Sierra data, max charge for this load would be 29.6 gr. I did load some at 29.3 and 29.6 but only shot a couple of the 29.3 because I saw some rips from extractor. Those were at 2848 fps. Since pulled extractor and cleaned up contact area. It needed it.

Just picked up 8lbs of AA2460 to use with some of the 85's I picked up a couple of weeks ago. Sierra lists 31.7 max for 3000 fps. I'm sure there's plenty of room to find a mild shooting node there at a good velocity.

I show several that I have pre-loaded into my spreadsheet for the 85's, from the Hodgdon mag, Sierra, and Western powder data...

Mag,,,,,	H322
Sie,,,,,	Tac
Mag,,,,,	H335
Sie,,,,,	RE-10x
Western,,,,,	Acc 2200
Western,,,,,	Acc 2520

In the grain-weight arena, for the 95 Vmax I find H335 and Xbr to be close in weight and performance. In the Speer 90 Tnt (Hodgdon manual) the Xbr loads ~0.5 gr below the H335 loads and ~50-100 ft/s slower. H335 is listed in Hodgdon for 85gr but Xbr is not.

6.5 Creedmoor: 40.0 gr of MP580 [IMR4166], 2.55" OAL, 3307 fps, .34 MOA

6.5 Grendel: 27.8gr LT32, 2.135", 2810FPS, 0.9 MOA

6.5 Grendel: 27.8gr LT32, 2.135", 2810FPS, 0.9 MOA

And 30.0 gr ARCOMP gave 2947 fps and 0.7 MOA. Might be too hot though, bot sure on that one. 20" BBL 1/9

Has anyone tried LVR with these bullets? I know they are lighter than most seem to load with that powder. Works great with CCI-450s and 123gr Nosler CCs for me. I just got a bunch- that's why I'm asking. Haven't seen IMR8208XBR in months and my H335 is pretty much spoken for.

Thanks for the help!
