Everything I've read and researched is 50/50 on this. What to use?

Buy multiple reloading manuals, and study them. If you have a buddy that reloads, work with him for the first couple of times....

Magnum primers... try looking at the Reloader powders.... the results just may surprise you in a very good way.You are correct, there are probably better magnum powders on the market today. I just can't seem to stop buying the same powders I was using 20 years ago. Although I have switched to Varget for the .223.

RL-22 and 165 BT's and Accubonds have been the ticket for me, the last Remington Sendero I had in .300 Win Mag shot everything I fed it well. RL-22 gave me speed and accuracy, I've learned over the years the .300 Win Mag cartridges likes to be pushed, it performs excellent at it's higher velocity range.
My last Sendero .300 Win Mag all factory, I put 2400 rounds through it and sold it. It was a easy rifle to drive and just plain shot well for a out of the box rifle. The .300 Win Mag is not shy of being jumped, the bullet seated a ways off the lands.

Here are some groups I dug up with the load data I always write on the targets and keep in a file for every rifle. I hate digging a rifle out later and not being able to remember the load data.

This was a group shot at 400 yards with my favorite load through a Rem700, with a slight right to left breeze, I know I would be on paper so I didn't correct for any wind. I just wanted to confirm my drop, using my standard 300 yards zero. I wanted to check my real world drop at 400 and make sure my ballistic program was right on. Which it was, the program was right on with my drop. This group was shot from the prone off a bipod. I was using CCI 250 Magnum primers because I had ran out of Fed 215's. The federal and CCI's performed about the same, I felt the Fed 215's may be a bit more accurate with my load but I could have just been slapping the trigger tighter on those days.

You said the 300 likes to be humped quite a bit. The COAL for the 168gr AMax's I was using today is 3.340. But when I run a loose case and Sharpie'd bullet into the chamber, I'm getting a COAL of 3.480-3.482. That was with 5 different bullets and 5 different pre-sized cases. Is it normal to have THAT big a difference in book COAL and actual COAL? I'm just wondering if that big jump is why it isn't shooting to what I think it's potential is? It's a Douglas barrel, if that matters

Yes, it is perfectly normal to have that much of a difference between the books COAL and the real world COAL of your choice of bullet touching the lands in any particular rifle. What I would do and what I have done with many .300 Win Mags is start with the bullet just " Kissing" the lands.
But remember the COAL now may become a issue. It is loaded to touch your lands and that overall length may not fit down in you mag box. Which most often than not is the case, take a fired cartridge, set a bullet in it and seat it just deep enough so that it will go down in your mag box and measure that.
I can almost bet it's going to be longer than the book COAL but it will get you closer to the lands. Close isn't always better, just like with some Bergers. Some Bergers like to be seated just " Kissing" the lands or from between .010-.015 "Jammed " into the lands and some I have had to back off in .010 increments until I'm .040 thou off and hit the sweet spot.
What I was saying was that with several of my Accubond loads in a .300 Win mag, I can seat them just kissing the lands or .030 thou off and the rifle will still shoot the same. It's a very forgiving chambering unlike many 7mm cartridges I have loaded for.
For example, bellow are three different targets shot from the same rifle pictured in my post above. I was tinkering with the seating depth with the same bullet, the 165gr Nosler Ballistic tips. I do allot of the load development with the BT's because they are Nosler factory seconds at a fraction of the cost of the 165 Accubonds and they shoot exactly the same.
Also take into consideration your A-Max has a Secant Ogive which in my experience very rarely in .30 cal likes much jump if any. It's a completely different outer ballistics creature from let's say the Accubond, you may have to switch bullets. You would have better luck and accuracy from lets say jumping a Sierra MK then you would a A-Max or a Berger for that matter.
Note the difference " Extreme" in seating depths and for a factory rifle it is still shooting well.
This was a 100 yard group with the 165 BT seated at 3.345 and my rife zeroed @ 300 yards, my preferred zero for the .300 Win Mag. I'm still holding hair a little past 400 yards, also with a different powder than my RL-22 load.

This is a group shot at 300 yards with the 165 BT's. The first shot was out, with a warm but just cleaned bore. Note the seating depth 3.550

This is the same 400 yard group posted above note the seating depth 3.450. A extreme spread in seating depths with the same bullet but still very capable of MOA of Rockchuck well beond 400 yards. Very forgiving chambering and at extended ranges the BT's flat destroy Mulies. I have killed them a little over 600 yards with the 180 BT, in fact that particular Muley was head down feeding and I flat knocked him of his feet at that distance "Bang/Flop". That was before the arrival the the Accubond.

Curious on where you got the Sendero in the pic? I had one just like it that I bought in 1998 (Junior in High School) that was set up EXACTLY the same way. I sold it to a guy in spokane when I was a freshman in college.
Just curious if it could be the same rifle? It drove tacks and accounted for 100 or so 'yotes while I had it. Shot bugholes with 165 BTs and H4831.

I was just going to post a thread asking for some chrono readings for the 300, as I haven't chronoed any of my 300 rounds and was curious what guys were getting compared to the manual data. i know its different for every rifle and such, but am still curious what some of the readings are you've got. I bet you have some Biggerhammer. I am most curious about the 200 accubond. Are you getting much over 2900?
Thanks!
I run my 165 Accubond load right at 3300fps, and with that speed and bullet I have felt no need to go to a heavier bullet for anything inside of 600 on Deer, Elk or Beer. If I feel I may be shooting further, I'm running a 260gr Accubond with a RUM case pushing it.
