I have the 26" bbl 5R Milspec. With the 210 vld touching the lands, the 215 Berger touching the lands, and the 208 about 20/1000's off I have had EXCELLENT results out to 1200 yards. R22, H1000, pp4000mr, and even Retumbo.
My go to load is 77 grains of H1000 with a 208 amax with Norma and RP brass ( depending on what I've got ready to load)
I was doing some testing the other day for a "little project" and found an excellent load. 75.3 H1000 ,Nosler brass, fgm215, 200 smk at 3.445 coal.

You might need to tweak that seating depth and tighten up that group a little, instead of two tiny groups, it might shrink to one teensy tinsy group.
nice shooting, pard.

Yeah yeah yeah........
Scary accurate, Sierra 240 SMK seated .002 off the lands, 75 gr. Western Magnum, Winchester cases, Fed 210 M (not magnum!) primers, 2750 fps from my Remington PSS. Holds MOA, which, for a box stock Remington, is "scary" accurate to me, ' specially with me driving it...

Hey Aimsmall, I have a 30" Rock 5R and have been following most of your stuff that pertains to .300WM. Your posts have been pretty helpful in my load development for this rifle, and I read that you are diggin' that 208 Amax with about 72gr of Power Pro 4000mr, but lost you after that. I am about to test that powder using 220SMK's and later HDY 225's. Have you messed with those bullet weights using 4000mr? Thanks for all you do, by the way.
Man I haven't but I would think that about 69 grains would be a safe starting point as long as your loading long but not jamming. I was looking at the Hornady manual earlier today and it lists the 225 bthp match at 67.6 as max at 3.340". You and I both know that you'll be loading alot longer than that. So id imagine you'll be in the 69.5 to 70 grain region at around 2830 fps. Depending on case capacity... Thanks for the kind gesture and good luck. AS
I have a 26inch model that I had threaded. It was a laser with 190grn black hills. It's currently at gap getting a new barrel and the action is gettin tuned up, had a stiff bolt cloing on live ammo-no bueno. It's a great gun for the price.
I have a Remington 5R 300win mag, 26 inch barrel. 20/1000 from the lands 208 Amax 60.9gr ADI 2209, Federal brass with Federal 210 primers. That thing is a lazer, I never thought that a factory rifle would be like that. Each shot touching the next, clover leaf!
I am not sure if you have checked your velocity but you are most likely much slower than you should be. Although you have an accurate load you are significantly undercharged. ADI recommends starting 63.0gr and max charge of 66.0gr with 2209 and 300win mag and ~200gr bullets. They state that 63.0gr (which is starting charge) gives velocity of 2650ft/sec from a 24" barrel. So at 60.9gr you are probably running slower than some 308s running the 208 AMAX.
Man I played around today with mine underneath my cabin ( above ground) cause its raining. I ran some tests on 4000 mr and R22 with fire formed rp brass and a 208 amax. Both 30 to 40/1000's off the lands. It's hard to tell which shot better considering that they all basically hit the same hole.
You guys need to try out PP4000mr. It's BADASS. Accuracy is incredible with the 208 to 215 range bullet and pushes them REALLY fast. I won't shoot it alot bc I'm pretty sure it's temp sensitive but for trying to get the most speed out of your rifle it's the best I've seen. Basically take a hot charge of r22 and add 40 to 55 fps and that's 4000mr.
Here's 6 shots with 72.4 pp4000mr and a 208 amax at 125 yards. First shot was high left then the last 5 were that ragged hole

You missed the bullseye??? Nice shootin mate. Thanks to everyone who posts info on here. Aimsmall has helped me out as well. Thx again. fyi midway still has 230 bergers available.
I'm sure that bullet was SCREAMING! With 2000 mr I'm able to push it 2830 fps out of a 28" tube in .308 Winchester. Considering I was at 2980 with a .300 win ss5r 26" bbl and a 208 amax with 72.6 pp4000 ... You had to be WAY ON UP THERE in feet per second. Would be a damned good hunting load. If I may... What's your charge weight for the 185 ??
Aimsmall , I'd like to know what success you've had with the 210 VLD and H-1000 . What powder charge and primer ? and what charge weight before pressure signs appeared .
I'm working up loads for my Sako AV /Douglas Premium Barreled hunting rifle . I've read that this bullet likes to kiss the lands , is this the case in your experience ?
Thanks !

I found a good node at 76.5 grains h1000 , FGM215m. It was a hunting recipe and I really didn't tweak it that much. But yes, to the lands question... They love to be nice and snug in all my rifles except one. So, in all likely hood get ready to load long. But those bullets are SHEER HELL on deer. Makes trailing a thing of the past generally speaking.
