I'm looking to develop a long range ( to 1000 yrd) elk load for my 300 WM. I'm considering an Accubond LR 210gr, Berger 210gr VLD Hunting, or Berger 215gr Hybrid bullet. I want to use a temperature insensitive powder. I think Retumbo or H1000. I've read numerous threads on this site but am still confused and not sure where to go. It is difficult to find loads as well as terminal performance information with these variables. The load data books and online sources are not greatly helpful either. Please HELP! I would greatly appreciate any advice and experience that y'all have on how these bullets perform at range (near, medium, and long) on deer and elk as well as any information on starting loads to max loads that you have developed with these powders and bullets.
Many thanks!!!

Thanks all for the info!

My rifle was made by APA. It is a Rem 700 action, has a Rock Creek 25" barrel with a 10 3/4 twist, and has a Nightforce 5X22 scope.

The thread that Jeff recommended convinced me on the 215 Hybrid. I will have to see if it will stablize in my rifle. It seems to me that the loading books recommend anemic loads, even the max ones. I did a ladder test with this rifle using an Accubond LR 210gr bullet, H1000 powder, Federal 215M primers, and Lapua brass (new). The bullets were seated just touching the lands. At 80.5 grains I saw no pressure signs. I did not like the pattern though. That's why I thought of trying other bullets or Retumbo.

Jeff, a .040 jump is bigger than any I've tried. Is the reason you did so just to be able to get the rounds into the magazine? Your thread that you recommended is fantastic information. Thanks for putting it all together. I am interested in hearing further results. May I PM you on a couple of questions?

Again, Thanks all!

Myself and a friend just built two 300 Win Mags. We are both shooting the 215 Berger at 30 Thou off with a muzzle velocity of just over 3000 fps. We used a reamer design recommended by Broz. We could not be happier with the way these two rifles turned out. Both guns have Extended boxes so they fit the mag. If your gun stabalizes the 215's I wouldn't look at any other bullet. We are using H1000 and Fed GM 215M primers. It just works.

To be honest I used a .040" jump because that was where my rifle shot well with the 210 VLD. No rhyme or reason, just where I started with the 215 and it shot bug holes. I have a Wyatts mag box and can load as long as I would want to.

We have seen the 215 in 300 win's shoot well at many seating depths. Some much farther that -.040" some closer. This bullet was the easiest to get to shoot well I have ever worked with.

Glad you found some useful info in the thread. You are welcome to PM me if you like or we can do it here. Either way is fine with me. If I have answers I would be glad to share them.

I've kind of fallen into a rhythm with the Hybrids in the last few rifles I've loaded. I converted my 7mm REM from VLDs to 180 hybrids in six shots. They came in at .050" off the lands. I went back and tried it with my 300 WM that was previously .080" off and shot tighter groups at .050 off. The first time I tried I completely skipped over the .050" off the lands because I was testing .020 increments. (.020, .040, .060 etc.) While it's true the hybrids will shoot well at several depths, there is a spot in the .040-.060 off that they shoot lights out.

Once you find an inherently accurate powder charge, load a series of bullets at .040, .050, and .060 off the lands. One of these will be tighter than the rest. Don't be afraid to try the 200 grain hybrid with your slower twist.

drpbroun5,
For RETUMBO we show a starting load of 75.5 grains with a max load of 79.6 for the 210 VLD. approximate velocities are 2719 to 2874 FPS with a fill ratio of 107% ( = compressed). For the 215 HYBRID TARGET we show 74.0 start, 77.9 max. Approximate velocities of 2686 to 2836 FPS. Fill ratio of 107% (=compressed). Suggest you go to our website and check your 1-101/4 twist rate with these two bullets to see if its adequate before you start your testing. The 215 calls for a 1-10" twist and the 210 calls for a 1-11" twist rate. The 210 will show less compromised BC than the 210. You may want to sub the 190 VLD for the 215 due to your twist rate. Also check out Erics article "VLDs,Making them shoot" in the Blog on the website for some load testing insight. If you have any more questions please feel free to either contact us here or a [email protected] bullets.com.

I have found that Retumbo gives an awesome combination of great speed and accuracy. In my 300 wm, I got the 230's over 2800 and 215's over 2900 using 76.6 gr Retumbo in WW brass with a Fed 215m. I was absolutely amazed. Initally, I thought the numbers were off, but they bore out during confirmation out to 800 yards. I also have some 215's loaded into R-P brass cause that was all I could at one time. It was hard to find the 300 wm brass for a while. They shoot extremely well also. No pressure signs in either brass.

It is really tough to go wrong with the 215 Hybrid in the 300 win mag. I think the Berger 210 Hunting VLD is another great option, but after reading through the field testing results that Jeff (Broz) posted about the 215 Hybrid, I worked up a 215 load in my 300 win mag.

And just for reference, my 300 win mag Hart barrel, 1:10 twist, likes .085" of jump with both the 210 VLD and 215 Hybrid. I also have a Wyatt box and can seat out as far as I want, but I'm getting 1/4 MOA accuracy at .085" jump. So that is just proof that each rifle is different and you need to run seating depth tests to find the sweet spot on your rifle.

Good luck!

And for full disclosure as to how I reached .085" jump, I did all of the seating depth tests with the 210 VLD. .085" was the sweet spot. At other seating depths with the 210 I was getting about 3/4 MOA +/-.

When I tried the 215, Jeff recommended I just drop a grain and keep everything else the same, and that worked like a dream. The 215 maintained 1/4 MOA. But technically speaking I have no idea how the 215 would shoot at other seating depths, and have no reason to try and find out. I'm happy with it at .085" jump.

i will deffinately continue following this thread. i am also doing load work up on a new custom 300 win mag using most of these same components. 210 VLD hunter, H1000, Nosler brass, and Fed 215M primers. Good to hear about the 215 hybrids also. may have to try a box of those also.
