Mark and I have been playing with some 300 loads and hit what we think is the low node. We tried 74 grains, MOA, 75 grains 2 MOA
76 grains, BUGHOLES. 5 shot group under a nickel. Maybe .25 MOA.
It was only running 2860 fps or so with a SD of 7.

77 grains SUCKED , all over the place.

We are going to try 78 , 79 and 79.5. Hoping to find a hotter .25 moa load.

I was pretty pumped up. Never had a 300 shoot like our 308's. another range report to follow.

I've been reading a little on low/high nodes. Would you prefer an MOA gun that shot 150fps faster, or would you like Bugholes at 2860ish? Maybe a little hotter 20 fps since the chrono was 7 yards away.

A friendly word of advice, don't go chasing waterfalls. There is no need

Please expound. The thinking is that we hit the low node and may hit the high node closer to 3000 fps.

This barrel has shot 90% of the loads around MOA. Note all these loads are very nice handloads but I still see a difference. It's an M24 profile, it is beefy. Very impressive so far.

What I meant was, you have a good load, you guys
punch paper and smack steal right? 2860fps is fast, plus if your ES is as low as your SD I would not touch a thing and thank the reloading gods for your luck!

You have to ask yourself if chasing some mythical numbers is worth it? Whats is that going to get you at 1500m, 150 fps? Run the numbers in your pda and tell me if its worth chasing when you already have that load? If your out of adjustment then maybe.

But just for your consideration, I'm running a 27 1/2" blackstar 1-10, pushing a 185g VLD at 3030fps with a 81g charge of h1000. I cant go any faster, I could not safely push a 208g AMAX over 3k fps.

If your going to try anything try another primer first a cci 250 maybe.



You did not list ES?

Good... OK. Yeah. We have a handful of hotter to test. If nothing shakes out, we'll lock right back in on the first load.

[Pappabear]

I agree, we agree. Our 77gr SMK with H322 isn't super hot, but it stacks holes and we get hits at 1k with it. Nothing wrong with using some XBR and get great results either, a little hotter.

That load is in my SHOOTER app at 2886 is taking that Amax to a mile supersonic. We loaded another 20 of that load to re validate it.

That may be the high mode for the 208 gr amax in 300WM? We"ll let you know.

That seems like a really good load. You might be at your high node. If you really want to find where the nodes are you guys should run a ladder test at around 800 yards. It will let you know if there is a higher node. It will also do it with less rounds.

With the sd number you have I would not go any further, unless once you get out at longer range and performance suffers.

[markm]

Thanks for the input, guys.

[Pappabear]

As we thought, we played with 78 and 79 grains. No go. Both shot half ass. 76gr is our load.

Here is the tool.

Pappabear and Markm what length is the .300 Win Mag Kreiger barrel thanks.

[Pappabear]

26 I'm pretty sure. I'll double check though. We just did Chrono data on this gun on Sat.
208 AMAX RWS BRASS , 2946 fps

Mark is shooting the 5R with quicksand can. 2843 fps. 24 inch barrel

[markm]

I'm ready for a NEW CHAPTER! Maybe some 284 Ackley Improved?

[ICANHITHIMMAN]

OH that sounds like a great choice

[archad]

I just got back from the range. Here's is what worked for my .300 win mag stiller action, 25" bartlein m 24 contour. 208 amax H 1000 fc brass 77 grains 5 shots 2969 fps. SD is 9.My last shot was my flier:( overall real happy with this load.

Pappabear,

What shooting mat is that with the post to load off of?

[Pappabear]

Mark and I took Blackhawk matts , ( the one with wings I can't remember) and rigged those poles to the matts. They didn't come with those. Just rig your own up.

[archad]

Those pvc poles are great for preloading bipods. I have done the same to my voodoo tactical shooting mat.

If I can remember, I took the matts to a "shoe repair - luggage repair " shop and had the guy put in a few eyelets. And that Mat with wings is vodoo now that you mention.

Good kit

Nice. You can't really beat that 208 AMAX... even playing with the BERGER 210 VLD.... We still went right back to the 208.

[mattexass]

Thanks for that Papabear.

[ICANHITHIMMAN]

OH no here I go again, have you tried the 215 or 230 HYBRIDS yet? I have a nice raged hole at 318 meters with my WSM that's begging for you to best it............

[markm]

Haven't tried those. We'll keep an eye out for them.

[1slow01Z71]

In craptacular winchester brass my 26" 5r likes low 77s worth of H1000 loaded .02 off the lands or 2.884 to the ogive in my gun. Tried closer and got pressure signs much quicker. Ypu cant beat the 208s for the price plus I can use them for subs in my blackout. Skip the lighter bergers and go straight for the 230s if you really want to push the win mag. Thry basically net you the same performance as 338lm with less energy obviously. Its pretty crazy how the 230s run.

If youre thinking 284 why not go 6.5mm and have cheaper ammo with less recoil while having comparable ballistics. The 162 amaxs arent even in production right now that everyone loves for the 7mm bore target shooting.

I was being sarcastic. We have an ADDDDD friend who was about to dive into that.... came to his senses and went 6.5 284.

[1slow01Z71]

Why do yall do such large steps in powder charge? .6gr is enough to get totally in and out of an accuracy node in my factory 300wm 26". For my gun anything over about 77.6 wouldn't get me much more velocity. 77.6 to 78.4 gained ~30-40fps and made for a smokey shot. Clearly I ran out of barrel for the charge. My ejector marks were consistent from 77 to 78.4 with no crazy flat primers just a hair of loss of roundness with 215Ms.

[markm]

Because you GO BIG, or GO HOME! :dirol:

Shoot... I can't even remember what the thinking was on this originally (10 months ago). But yeah.. you make a good point.

[1slow01Z71]

Pappabears 300WM is shootin so damn good, wanted to make sure I wasn't missing out on something. Im kinda wishing I had a 28" pipe or so since Im not seeing much velocity gain past 77.6 but Im getting a consistent 2900-2910 with that load so I guess that aint bad for a 208gr bullet. What kind of accuracy are yall getting once you stretch it out?

[Pappabear]

If we can read the wind, we can stack them up at 500. Keep sub MOA. I take everything with a grain of salt at 500. So many factors. We frequently will shoot a fist sized group on say, the top right quad of the target at 500-1000. When we hit, we say"shoot the group" as opposed to going for perfect center shot. And shoot nice fist sized group at 1K. Next at bat, I'll get sloppy and completely miss the target and go full Tard.

Yea, anything over 2900 with a 208 is awesome. That's kick ass.

Yea, I think 26 is the sweet spot before it gets too long. I just did a build and considered 24, but my gunsmith gasped at the thought. But adding a can gets it out there. I agree about 24-26 burns all the powder. 2 inches on our 300's 24/26 is worth 100fps. But there are many factors.

[ICANHITHIMMAN]

My 300 win is at the smith right now having the barrel chopped down to 25" from 27 1/2". I came to the realization, that with the hunting i do and the range access i have, shorter was not going to hurt me at all. Also velocity is my last concern.

[markm]

SBR that damned thing then! And put a pencil barrel on it!! 10.5 sporter pencil barrel Win Mag.

[ICANHITHIMMAN]

LOL I will give you some numbers when I get it back. I have about 10 rounds of my old load witing to see what the numbers say. I was at 3030FPS chopping off 2 1/2" will see what happens.
