Load data for remington 788 6mm 87 gr Bergers

[henke4310]

Iv been looking and trying for quite time now and iv came to swallowing my pride and asking the pros for help.
What iv been tring is H4350 45, 45.5, and 46 grains with no luck. The COAL iv found that works for guys online in a 6mm was 2.903 and that wont fit in the mag so i backed in down to 2.866. My best group so far is about 2.25 inches at 125 yards. So needless to say im not really impressed. So if anyone has any experience with 87 gr bergers in a 788 id love to hear about it. Thanks guys

Look at the reloading section that notes on starting out how to find "The Load" for your gun. I have found, and seen that the Bergers, more often than not, like to be jammed into the lands just a tad bit. Run either the OCW or Ladder test, starting with jammed bullets and start from the bottom and work up.

<span style="color: #3333FF">First, determine what twist you have in that rifle.

<span style="text-decoration: line-through">First</span><span style="color: #3333FF">Second</span>, I would suggest seeing what you get with Speer and Sierra 85-90 gr. bullets. If they don't shoot you either have a rifle problem. Or, a shooter problem.

From my experiences 4350 just works outstanding out of the 6mm Rem with 85-87 gr. bullets.

You might try the Nosler 90 gr. bullets as well.

The loads you speak of are right in the ballpark for that weight of 6mm.

As noted previously, if the other bullets of that weight aren't working, you have a rifle/shooter problem. If those bullets are working, I would think the twist in your rifle may not be enough to stabilize the 87 gr. Berger.

A little history on that. Remington introduced the .244 Rockchucker (6mm Rem) in the model 722 in 1955 with a 1-12" twist. That didn't sell for them because they (as Remington usually does) miscalculated the public's desire for a deer rifle. A rifle can shoot anything else, but in America it has to be able to kill a deer. So, that said, after 1958 they changed the 722's to a 1-9" twist. When the model 700 was introduced they changed the name of the .244 Rockchucker to 6mm Rem (Magnum at first, but that was dropped) with a 1-9" twist. In the late 60's early 70's they came out with a "cheap" model rifle, The 788. I have heard both stories on the 788 about 1-9" or 1-12" twist. If yours has the 1-12" twist it WILL NOT stabilize the LD type bullet the 87 gr. Berger is.

Everything iv read about the 788 indecates that it has a 1 in 10 twist but i could be wrong. It shoots factory rounds really good and iv been wondering how the 87 grain bergers would work on coyotes is the only reason iv been messing with them. But ill try some Speer and Sierra and see what i can get to work. Looks like i might have to sell the 788 and build a 6mm ackley off a rem 700 to try the bergers. Oh well Haha thanks for the help fellas.

A 1-10" should work but still might be 'iffy' for that bullet. You could go to the flatbase and have no problems.

Again, though, see what other bullets in that weight do. If they work fine, it's that bullet/your rifle. If they don't work fine, then it's your rifle. Assuming of course you have another rifle you can go out and shoot the groups you mention. Meaning, you are on your game there.

I cheat in load development and shoot off a led slead so i cant blame it on my shooting lol But the bullets are rated for a 1 in 10 twist im just thinking i cant have them seated far enough out to make them work. No big deal just wanted to give them a try.
Thank you guys for all the help this sight is absolutly awesome

For Yotes, look at the 75gn Vmax. Depending upon the rifle, it should give 3400fps pretty easy.
