Home Forums Reloading Big Game Rifles Selecting the right large rifle primer

If you don't like it here, feel free to leave.

Wish he would. Ooops my bad . So informative. Quit quoting the pecker head and I won't miss him.

What can I say about a bunch of Yo-Yos that are below my level of intelligence.
I'm traveling at the speed of light and you clowns are not even potty trained yet.

So your Enfield puts 5 250 grain bullets in one hole at 200 yds or not. I'm a fxcking plumber and figured that out before the internet. Talked to people who hunted Africa. Get lost dipshit.

I thought this thread was about primers, what about getting back to the point of thread. Rio7

"Little Larry" (because he's half Larry Root, half Little Twig) doesn't know anything about primers. Since he would be unable to sufficiently stroke his ego by returning to a discussion on primers, he couldn't possibly let that happen.

Now eddie, I stay quiet to learn things, never have much to add, but guys like you though, well just easy pickins really. I am not above a free bash now and again.

I started reading this thread to learn more about primers, as primers have had a affect, on some reloading I have been doing lately. Rio7

Rio, Primers can have a huge effect.

What kind of issues are you seeing?

Sniper, I have been messing around with a 6.5 X 284, using all CCI primers, and IMR-4350, 142 gr Bullet,I have found when I change primers that it has a big effect on the groups I am getting, and some difference on the speed I am getting, CCI-200 shoots great, MLR shoots good not great, 250 Magnum and BR-2 shoots patterns.
What I don't know is why??? Rio7

Rio, that's exactly what I would expect.

In my experience, a small to medium charge of an easy to ignite stick powder like IMR-4350 Performs best with a cool primer. In these instances, my favorite is the CCI-200. Imagine you are just giving the powder a nice consistent small flame, as opposed to scattering it with a flame thrower.

On the other hand, hard to light ball powder tend to need the flame thrower....you don't want to be on the edge where it's trying to decide how well it's going to light for you.

With stick powder, my general preference is CCI 200 up to an "06 size case. Bigger then that I will switch to a magnum primer. I've had good luck with the WMRP, so that's my typical goto primer in something like a 338WM with 4350.

It is interesting to note I can shoot submoa groups with both CCI 200 and WMRP in the .270 Win, however the POI will shift a full foot vertically with the Winchesters shooting higher. I've repeated this phenomena in multiple rifles.

Sometimes getting a load to group is all about the primer. In my STW I'm shooting a heavy charge of a surplus ball powder. I've tried about every primer you can imagine, and the only one that give me good groups are the FED 215's.

Bottom line is primers do matter, and for best results you do need to match your primer to your purpose.

Why is because you forgot what Dennis Hopper said in the movie "Easy Rider". Your getting bad vibes man, your getting bad vibes. Meaning changing primers changed the way your barrel vibrates. And I bet antelope_sniper didn't think I "node" that.



There are two ways to change barrel vibrations, change the up pressure at the fore end tip or vary the amount of powder with your existing primer.

And from the same people who brought you the "Strain Gauge" method of chamber pressure testing.

That's just funny.

Maybe someday you will do enough shooting to understand why.

And yet another troll goes on ignore.
