My nephew bought one of the closeout Rem 798's in .308 Walnut, and he's stopping by to roll some of his own.

I've got some Hornady 150 SSTs I was thinking about using, and I'm desperately trying to reduce my stock of W748 (received via a trade).

Any success with a 150/W748 combo in 308?

I have used it for years just recently started using RL15 and Varget

748 works fine gave good accuracy and was the demise to many whitetails for me and my cousin

I used a load similar to the one above, and it gave fantastic accuracy in my old70 FWT.

Have used 748 a lot in the .308 with Hornady 150 grain Spire Points. Have used this combo since the early 80's and it is an excellent powder for 150's.

Depending on your rifle 48 to 49 grains shoots great and will give somewhere in the 2800 fps range in 20" to 22" barrels, i.e. between 2800-2900. 49 grains can be too hot in some rifles (although I have gone to 50 in one particular rifle I don't recommend it) To be safe start around 46 grains and work up.

Especially with that SST eating into the powder capacity a bit.

My pet load with a 150 Hornady Spire Point and W748 was 47.0 grains. That was close to warmish in my rifle (a rear-lug Rem 788) so it ought to be fine in most others.

C'mon, I got those loads straight from Bob Hagel. What could be safer?

Dunno, maybe loads from Paco Kelly?

I used to use something like 48 or 48.5 with the flat base Hornady too. But the OP did mention the SST.

I've had good results with 748 in the .308, but like either Varget or IMR4895 better, at least in my rifle.

I do not like what those particular bullets do to up-close deer. They are very frangible. I used them out to about 50 yards or so, and they were too explosive. If you are going to have shots that are 100+ yards, then they may behave better. They are accurate, though, which leads me to believe they (the SSTs) would be an excellent long range bullet.

They definitely have that reputation, though I've had good luck with both the 150's and 165's out of my '06. I bought a couple of boxes of the 150's for an antelope hunt; they performed admirably on a 300+ yard buck, but I'm left with quite a few and prefer the 165s for deer. So, my nephew is getting leftovers. (I don't think I own any other 150's.)

At this point, they're strictly for paper punching, but I wouldn't hesitate to send him off after our resident mulies with that bullet.

W748 & Sierra 150 gr. work best in my 99 and 700 in 308. I'm unclear on why these two rifles didn't do well with Varget or the 4895's.

At 300 yards, they probably are in a velocity window that allows them to "behave". And I would definately use them at that range. As I said, they are accurate.

He oughta do well with that combo, then.

The load in my rifle is 48.0g with a CCI200.

Starting from scratch, I would go 47,48, 48.5, and 49g stopping if I ever saw any pressure.
