300 WM 208 ELD-M load

[Zeke-BE]

Awhile ago I bought a long range 26" heavy barrel Remington rifle. It just sat there for a year. I never had time to get to it, plus I wanted to put a break on it before I did anything, so it just sat. I never even shot a round out of it. The gun smith who put a muzzle break on it was the first guy to shoot it.

 

Well I grabbed 208 grain ELD-M because they didn't have any of the 212 ELD-X at the time. Now there are plenty of them around. But from what I've seen the new ELD-M are near the same as Amaxs but with the new tip. If you have heard other wise please comment. But now im ready to see what it can do.

 

Remington rifle 700

300 win mag

H-1000 powder

COAL- 3.608 which is 0.025 off the lands and this keeps me inside the magazine

208 grain ELD-M Hornady

Hornady Brass

 

I started off at --73 grains ave. 2712 fps

--74 grains ave. 2780 fps

-- 74.5 2805 fps

-- 75 2850 fps

--75.5 2868

-- 76 2880

 

This above was shot up in Flagstaff in July and my groupings were so bad. Then I realize my scope came loose But thats ok because I'm looking for a hot round to be busting on Elk

 

Yesterday I shot

--76.5 -2910 with a 1" group and a flyer

--77 2925 with a large group

--77.5 2930 1.6" groups

--78 2963 with a bad 2" group

and today I reshot 78.5, 79, and 79.5 to see if I can improve the grouping

 

Here is 78.5 grain. This was my second best

 

My number 1 spot!

 

My hot round 79.5

 

I have my shots listed on there too. 1-4 for speed. Notice the 79.5 slew down.??????? Then I load 1 round at 80 grains to see how far my gun will go. It shot at 3050 fps. Huh??? it shot about the same as the 79 grain. Now grant it it was only one shot, but I remember loading it, it was up to the top of the shoulder of the brass. No sticky bolt, no pressure signs that I can see, but im no pro at pin pointing pressure signs.

 

So Im going with 79 grain pushing 3050 fps with a 0.836 group. Now the next question to you guys is what else can I do to bring the grouping in. Im planning on doing a load test with shortening the COAL and see if I can improve my shot and move it out to 200 yards to see what comes of it. Any extra help would be great.

Here are some other shots

Lead sled might of helped loosen your scope

I did use that. Never had a scope go loose on me

I found out when I had my 30-378 that it will blow out scopes if you don't let em recoil freely. Could of been a coincidence though

I didn't put any weight on it though. I just didn't want to screw up any of my shots, but it still recoiled. Just not as bad shooting the gun by itself

[cjl2010]

We never did either. Could of just been a coincidence though but I've never used it since to see if it would do it a 3rd time

[DesertBull]

Just my opinion but I would develop loads and zero without the lead sled. I have found that velocity and POI are sometimes way different when shooting from the sled as opposed to shooting from a bipod or other rest like you would when hunting.

 

Also, with 75-79 grains of powder I would want to use a magnum primer instead if the 210's. I seem to lose consistency with large rifle primers at about 65 grains of powder.

 

Good groups though. Looks like you will have it well under an inch with some powder charge and seating depth fine tuning.

Play with length. Be more about accuracy then speed.

Agreed! But im hoping to get top speed and accuracy if I can obtain it, but Ill always go towards accuracy

Switching the primers to magnums does that help accuracy more? Or just keeps it from going inconsistency?

[DesertBull]

You probably won't notice much difference at 100 yards but if your MV is inconsistent you will notice it 300+

I shoot a very similar setup and have had my best groups with 210 primers. My sweet spot with H1000 is right at 76 Grains, try just below and above that charge and see what it does. You really don't need any more speed than you are getting, you should have no trouble taking down elk with the right bullet construction.
