http://www.adi-powders.com.au/handl...nch+Mark+8208&hdnFormName=frmPowdersIf that's the same stuff then here's a quote: Bench Mark 8208
This short grained reloading powder has aquired a deserved reputation among serious shooters for accuracy and stability over a wide temperature range. Looks like a claim of temperature insensitivity.

Yes that's what I was on about. It's the same powder.

FWIW, my sniper guys tell me that IMR 8208xbr is the most temp insensitive powder they've ever used. Snipers reload their own ammo? Travis

2850 fps should be a reasonable load, but you might need a grain or more powder to get there with moly. Finding the accuracy node for your barrel is more important.
I'm not a fan of RL15 for the same reason the military discontinued it. It's easy to find an accurate load with 4895 or 4064. Varget is too, but then Varget is hard to find.
I'd try a can of IMR 4166 if I were to ever run out of 4895...but that isn't very likely. What's your reason for not liking RL15? Travis

RL 15 works just fine. There's not much of a temp stability issue from what I've seen.... Just sayin..
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

Shot at least 1000 rounds of LC 168 "95 " as I remember also. This in a bolt gun..It was very good stuff and I believe loaded with 15.

JPro, My previous .308 liked 45gr of R15 behind the 155r Scenar in either LCNM or Lapua brass. That load clocked about 2885 but my barrel had a Palma chamber which only had .050" freebore. John 45gr R15 behind 155gr Bullets seems to be a good accuracy node in my rifle. Two different bullets, two different cases, two different primers but the same powder charge produce great accuracy for me. These are 10 shot groups. John ![[Linked Image]](http://i111.photobucket.com/albums/n159/Hondo64d/Targets/155grVLDR1545grTLRM3105OALmeasured_zpsbf3e00b3.jpg) ![[Linked Image]](http://i111.photobucket.com/albums/n159/Hondo64d/Targets/155grScenarR1545grTLRM3105OAL2measured_zps09949572.jpg) Here's a follow up on the 155gr Scenar load shown above. Shot these on Friday. 400m, 8" plate, .242 MOA ![[Linked Image]](http://i111.photobucket.com/albums/n159/Hondo64d/Targets/400m23May14measured_zpsc9372f22.jpg) 500m, 8" plate, .309 MOA ![[Linked Image]](http://i111.photobucket.com/albums/n159/Hondo64d/Targets/500m23May14measured_zpsf9577f12.jpg) Here's basically same load. 1/2 grain less though. 45gr in LCNM brass was showing some pressure signs. The lone shot is a 25 yard sighter after switching scopes and barrels. I had the .260 barrel on and switched back to the .308 barrel. After the 25 yard sighter, I moved back to 100 and fired these five from the prone off a bipod from the bed of my truck. It measured .358".

As an aside, the same day I was chronographing those loads in my .308, I shot a few factory loads through a friend's new left-hand 700LTR .308. The 165gr Federal Sierras and Fusions clocked an expected 2,575-2,600fps, but the Nosler 165NBT factory loads ran 2,800fps. I'm not sure what powder Nosler is loading there, but 2,800 with that bullet in a long-throated factory 20" 700 is cooking pretty dang good. No pressure signs either.....

When I first got the Palma chambered .308 barrel for my Stiller Predator, I ran a box of 180gr Federal "Deer Thugs" through it. Averaged a hair over 2700 fps. I was impressed too...

Chamber, throat, and bore dimensions do matter, don't they? Partly why I'm having to jack up the charges on these 155/RL15 loads. Loose factory chamber/bore, long throat, and moly, they add up. Was pleased to see that these Scenars might not mind a little jump, just from the few that I sent downrange. The Magpul magazine only allows a 2.85" COAL, but supposedly Accurate Mags will allow another tenth of an inch, provided the receiver is notched a bit under the ramp. Rifle feeds much more smoothly from the DBM than the factory BDL box. I may move my Rem Varm contour 6.5x47L to the same setup, as it's a bit balky sometimes from the factory box. Not really crazy about all the "polymer" components, but if they work.....

Me too.
My 270 Win takes 5 grains over "book max" loads to reach the speed listed with some powders.
Slow barrel my arse.
