Finally got out to the range today and put some holes in paper. These are my first reloads and I still have less than 150 rounds through my Hog Hunter. Given that I'm very new to centerfire shooting (notwithstanding the Mosin I had in the past and my SKS), I'm quite impressed with ALL of these loads.
I loaded all the rounds to a COAL of 2.79". Bullets used were Nosler 150gr Ballistic Tips.

looking at quickload that load is in the red and over pressure
those charges are right within Hodgdon online data spec. 44-47gn max

46 is a hot load - be careful. Not recommended for a new reloader.
If you re-size your cases incorrectly, it would not take too much more pressure to cause a head separation.
If you stick with FL re sized new brass, you should be OK.

According to Hogdon that load is at 66.6% of the load range and is not above maximum. Maximum with that powder and bullet is 47.0 grs. which is a compressed charge. So as long as you are not seeing any excessive pressure signs on the primers, such as primers filling the entire pocket and cratering, or if the bolt opens without excessive resistence or drag, I think your fine.
And yes, it appears you ahve found the sweet spot for your rifle and that load combination.

Yes, I used Hodgdon's load information for the 150gr Nosler Ballistic Tip bullets that I used. As I shot each round I inspected the cases looking for signs of overpressure. They all looked good to me.

I haven't shot any Noslers but a 28" .308 with 46 gr Varget and a 155 gr Lapua Scenar is doing 2900 fps and is a working maximum in my rifle.

For what it's worth, the Nosler #6 manual actually lists 48.5 gr of Varget as the max for that bullet (Fed 210M primer, 2.81 COL).

Hello there. I frequent and read a lot but don't post but I couldn't resist. 308 is my FAVORITE caliber to reload. and I my favorite rifle happens to be a Savage 10FP in 308.
Anyway, I've had great success with Varget. I found that there seems to be (2) sweet spots during load developments. Usually at the high point (looks like you found that). There is also a corresponding sweet spot on the low end. (I'm a wuss so I tend to use that one (except for my hunting rifle/rounds; I go on the higher end)).
In my Savage, I found 42.1 to be the sweet spot on. Easily .25 to .50 inches at 100 yards benched (5 shot groups). I shot a 2 inch group at 300 yards with that same load with a sling (no bipod) in the prone position.
One thing I noticed at least in my rifles are that OAL plays a big part in accuracy. I was getting .5-.75 inches regularly but only got into sub half MOA once I started to load pretty close to the lands (my bullets are pretty long at 2.880).
(I should add: Hornady Match Brass or Federal Brass + 168 grain Hornady AMAX + cci 200 primers. 41.9 grains of Varget)
What a fun hobby; few things are as rewarding as finding that sweet spot!

Thanks for the tip vujade. I might try out some lower charges in the future. My plan right now is to use the 46gr load and once I get some more trigger time (and improve my shooting skills with my new .223) I'll revisit working up a load for my rifle. I have no doubts that most of the cause of my large groups were due to my shooting and not the rifle or the loads. I wouldn't be surprised if ANY load that I tried would produce sub-MOA groups if I do my part.
