2400 with CCI 350 primer

[lead chucker]

Does any one here use mag primers with 2400 in the 44 mag with 300-310 gr cast bullets? I got a hole brick of these primers and would like to use them. The rifle will be a ruger 77/44. Bullet seated to top crimp groove so as to fit in magazine.

[winelover]

Exclusively! Start low and work up, slow, striving for accuracy. Heaviest boolet I use in my Redhawk and Marlin is the 280 grain WFN. Anything heavier requires site correction, if you switch to lighter boolets.

Yup, work great for me.

I've used 21.5 grns 2400 with a 240 grn GC and mag primers in my SBH and DE in the past. Experimenting with a 260 grn bullet right now. Made for a real stiff load. Wouldn't want to try it in a lighter gun.

All I'll say is that Alliant recommends standard primers only with 2400.

[429421Cowboy]

I'm with Rocky, i have only ever used standard primers in my 2400 loads per Alliant's warnings and never had an ignition problem.

[dubber123]

Alliant and Brian Pearce both warn of some strange pressure spikes and weird velocity variations when using Magnum primers with 2400. One or both actually reported getting higher velocities from the standard primers also. I would just pick up a pound of H-110/296 for use with the Mag primers if it were me.

[Alchemist]

Rocky & dubber are tellin' it straight. Lots of guys use mag primers with 2400 (and I used to), but standard primers work fine for me and I'm sure that Alliant knows a thing or two about the subject.

[bigboredad]

I have done it but I have done a lot of things when I was younger that I would't care to do again. I agree with by a pound of 296/h110

[LUCKYDAWG13]

+ 1 on the H110 yes i have in the past but dont need to now

Actually it's gonna take 3 1/2 Pounds of H110 to burn up that brick of primers. :Fire:

[lead chucker]

Thanks for all the info I will stick to my cci 300s with my 2400. I have allot of it so was looking for a way to use these mag primers. One thing though I have load date for my 45 colt with 2400 and mag primers. Any one use Mag primers with 2400 in there 45 colt. Mine is a new model black hawk convertible. The acp cylinder will out shoot the colt cylinder. It's a fun gun.

I also use the CCI 350's, exclusively in Ruger only 45LC loads with 2400, in my wife's Blackhawk. Come to think about it, I also use the 550's for 357's with that powder!

I tried 350s with 2400 to reduce the unburnt powder kernels. No improvement.

[429421Cowboy]

Rocky & dubber are tellin' it straight...
Yeah you wouldn't want to just take my word for it lol

[gofastman]

but standard primers work fine for me and I'm sure that Alliant knows a thing or two about the subject.

that is sound logic.

I like WLP's for almost all magnum loads.
I prefer to use CCI350's with W296, but even then WLP's worked fine in the 100 or so rounds I tried them in.

[Lloyd Smale]

Ive used them and still do. I work up a load usually with standard primers but about allways fool a bit with mag using 2400 in a new gun. Ive got some guns that just shoot better with 2400 and mag. But for the most part standard primers do the trick. Sure doenst hurt anything though.

[LAH]

I'm with Lloyd on this. My SBH loved the Lyman 429421, 21 grs. 2400, & a CCI350.

[Rocky Raab]

Casting no stones here, but if I'm faced with differing opinions about reloading safety and the two sides are:

Joe Reloader who reads the interweb and has a chronograph and a degree in the History of Musical Basketweaving

Versus

A team of professional ballisticianss with a million dollars of state-of-the-art testing gear and degrees in engineering, statistical analysis, and chemistry

Ya know what? I'm gonna go with the opinion of those guys.

(The Joe Reloader profile is for humorous effect, guys. Flamethrowers off.)

[LAH]

I understand Rocky but I could probably dig up a few manuals that used mag. primers with 2400 but not sure of finding one with a bullet as heavy as his. Besides you're better off listening to the big boys than listening to me. I have no trouble saying that.

I like the Joe Reloader Profile

[Lloyd Smale]

I have alot less problem giving out of the box loading suggestions to guys here then on any other fourm. I figure if your into this hobby enough that you are casting your own bullets your intelegent enough to work up to a max load. I know this sure isnt wrote in stone though.

[Rocky Raab]

Very true, Lloyd -- and you are one of the more trustworthy.

(Your experience notwithstanding, I wouldn't use magnum primers with 2400.)

Hmmm, I'm surprised this didn't get more attention![smilie=s:

surely I'm not the only one that sees the merit in using WLP's with 2400.
they seem like they would be the perfect match (I think there may be a pun in there somewhere) for a high volume case loaded with 2400.
The're more powerful than a standard primer, hot enough to set off a big case full of powder even in less than ideal conditions, yet are not quite a full throttle magnum primer
(this is what I gather from their packaging, someone correct me it this isn't true please!)

[Lloyd Smale]

Ill use aa9 as an example here. aa and a few gunwriters that do more typing then shooting claim that only std. primers should be used with it. Everyone i know thats actually worked with it and has a chonograph will tell you that it does much better with mag primers and as a matter of fact in my testing does its best with cci350s. two reasons come to mind why aa claims this. One is they worked up there loads with std primers and know that if you substitude a 350 pressures are going up and it would cost them money to redue all there data. The other is that theres a tendency in alot of loaders heads that max book loads are really starter loads. I know loaders who will routinely add 2 grains to any book load in about any gun. If there loads are really allready near max and again you substitute a 350 instead of a std primer and add 2 grains of powder on top of it your going to be in trouble. Much easier to get someone like brain pearce to claim mag primers arent any good in it. Anyone who actually put in the time with it knows better. Especially if your using there starting loads. Ive seen sd variations of 300 fps with standard primers and there starting loads and have even had hangfires with it. When they do there testing whos to know what the temperatures were ect. Combine a stand. primer a starting load and freezing temps and you will see what i mean in 5 minutes over a chrono. Im sure not saying that you shouldnt pay attention to what recomendations a loading manual gives you but to me its a starting point. It doesnt mean a guy is stuck with whatever they say. Thing is you just have to approach it with common sense. Something thats lacking in this world. You are not going to blow yourself up using mag primers with 2400 using loads that come from a loading manual. Anyone thats been around for a few years with the 44 mag knows that most of the data listed in manuals these days has been watered down quite a bit anyway. Get yourself a manual from the late 60s or early 70s and see.

I use standard primers (sometimes the WLP's) in 45 colt with 2400. My degree is in underwater candle making with a minor in duct tape art..

[30hrrtt]

I've used both depending on what I had and seen both in manuals. My first manual was the Speer 12. Only been reloading for a dozen years. It specifies mag primers for 2400 in both the 357 and 44.

Now using standard as they've been working great and I bought a case of them.

[leadman]

I use WLP in the larger revolver cases (44, 45). For the 41 I use standard. With the 180gr Saeco boolit in the 357 I get less velocity variance with the mag primer, but the 158s seem to like a standard primer better.
Still see many that still want to load the "Keith" load of 22gr of 2400 with a 250gr cast SWC. There is an example of Loyd's "add 2 grs". Here in phoenix in the summer 18grs is plenty of 2400.

[paul h]

In the 44 mag and 480 I've used 300's with 2400 and 350's with H-110 per the manufacturers and gun scribes recomendations. I'm often up for tweaking loads, but when I see specific recomendations for primers with a given powder, I follow them.

I'll also suggest that H-110 is really a better powder for the 300gr and heavier bullets in the 44 mag. 2400 is my choice for 250's and lighter.
