This has probably been beat to pieces but I had to ask. How many of you folks are loading 2400 with mag primers for a 44 mag? I've been using W296 with mag primers but finally found some 2400 today. The little bit of reading I have done so far has been all over the place. Any suggestions? Recipes? Thanks fellas. Cheers.
2400 and mag primers

Really depends on what you read. My Hornady 9th Edition suggest WLP for all the loads including W296 and 2400. My old Speer #12 Manual suggest a CCI 350 Magnum primer for just about every load. Using 2400 I have used several large pistol primers including WLP and also used Magnum primers and really never noticed a difference, they all went bang just fine.

You don't need magnum primers with 2400, but it doesn't hurt anything to use them if that's what you have.

This.
If you only have magnums, use them. That goes for any powder.

You may find you can use a bit less powder with the magnum primers and get the same velocity.

According to Handloader magazine, several times, Mag primers + 2400 will result in bigger extreme spread, and pressure spikes.
I'd use standard primers with 2400 if you have that option.

I agree, if you have standard LPP I would also use them with 2400. It's well known in the reloading community 2400 is more stable with a standard primer, after all, when 2400 was developed there was no such thing as a magnum primer! lol

As big 2400 user, I have always loaded with Magnum primers. I did a bit of experimenting and found that normal primers are fine. Once I burn off my stash of magnums I won't buy them anymore. Use normals if you can.

More 'mixed messages' from me.
Below is a 'spread sheet' copy and paste, sorry they don't transfer well.
The columns are:
Caliber
Bullet type
Bullet weight
Powder (O) indicates 2400 of the old formulation
Powder charge, Xs are not numbers
'S' = Standard CCI primers, 'M' = Magnum CCI primers
Average velocity at 10 feet, number of test rounds vary between loads. Rounded to nearest 1/10th
Weapon the tests were shot in
44 LSWC 240 2400 O XX.0 S 1079.3 S&W M29-2
44 LSWC 240 2400 O XX.0 M 1116.5 S&W M29-2
44 LSWC 240 2400 O XX.1 S 1088.8 S&W M29-2
44 LSWC 240 2400 O XX.1 M 1127.6 S&W M29-2
44 LSWC 240 2400 O XX.2 S 1148.8 S&W M29-2
44 LSWC 240 2400 O XX.2 M 1150.6 S&W M29-2
In my not as scientific as I would like test, I came up with the opinion that 'Magnum' primers will produce marginally higher velocities and little more. (I did enjoy the shooting.)
What I came away with as 'fact', further comparison was fruit less, the component combination was approaching max (sticky extraction) and the bullets used (Missouri Bullet) were hard enough and sized properly for my barrel, I am happy.
And for the 'mixed message', greater velocity WITH mag primers, I use STANDARD primers with (almost) all 2400 powder loads.
Remember, the destination is the goal, getting there is the fun.

With 2400 you don't need magnum primers. But at some point as the charge is increased, you will experience less, and less effect created by magnum primers in regard to consistent velocities. You might reach a maximum charge sooner with magnum primers also.
H110/296 is a completely different story, you must use a magnum primer, or risk experiencing a squib. I have a buddy who has insisted standard primers are just fine for 296, and it was for a long time. But it only took one event to changed his way of thinking.

My understanding is that while magnum primers provide a fairly small velocity increase when used with 2400, the increase in peak pressure is considerably greater than the small velocity increase would seem to indicate.
Since I'm shooting a 40 year old Smith '29, I dropped my load a half grain when WLP's were all I could find.
Better safe than sorry.
And anyhow, its STILL got more oomph on bowling pins than my .45 ACP's!
