Primer for 4350 or slower powders

[mander]

Does anybody use a Fed 215 (or similar) primer for 4350 or slower powders.

I was reading this site and they list primers based on the type of powder and was interested in finding more info on this topic.

I normally use Fed 215 when I am loading more than 60g of powder.

Use whichever primer produces an accurate load. That simple.

As far as using a magnum primer when loading over 60gr of powder, that is a good rule of thumb, but not necessary if not shooting in cold weather. In warm weather, most any primer (magnum or standard) will work reliably with charges over 60 gr.

I have seen a 'force' test where a pendulum is swung from the primer explosion; another captured pictures of the flash and produced load data from a strain-gauge-equipped rifle supporting 'low' flash/brisance primers (Tula/Wolf/PMC) with mid-range powders while another tester using a strain-gauge-equipped rifle found that 215 magnum match primer was necessary to ignite H4350 completely in a modest chamber (6mm-250 I think) otherwise there was a secondary pressure spike near the muzzle.

I, too, am honestly confused by the seemingly conflicting data but there is no clear winner - you must try several different primers. Fed GM210M's seem to do well enough in my 9.3x63 for cold-weather hunting loads using RL15 to A4350.

I'm using 215M primers in 284, 6-284, and 6mmXC.

Mander -

Howdy !

F.W.I.W. :
In my wildcats and w/ powders like I4350, WW760, AA3100, RL-22, and I7828; most of my best results have been w/ Fed Magnum match
primers ( whatever number designation those are ).

My gun(s)... my loads.

357Mag, that would be the 215Ms. Same ones that I use.

I think this is a simple one - follow the published reloading data for your caliber.

I have heard some "chatter" at the range about using magnum primers for 4350 loads that normally call for standard primers when extreme cold temperatures (below zero and beyond) are encountered. The theory being that magnum primers ignite 4350 more efficently than standard primers at these extreme temperatures. It sound right but I've never tried nor do I intend to - I don't like going off published data - besides, you won't catch me out shooting or hunting in extremely cold temperatures - not my idea of fun.

If you did hunt in these extreme weather conditions - perhaps an alternative to using magnum primers (where standard are specified) would be to keep you ammo inside your coat, next to your body until you are ready to shoot.

IMR4350 and faster I used std primers. Anything slower than IMR-4350 I change to Mag primers

 

[bigedp51]

Its a "loaded " question, in the manuals even with some of the short magnum cases standard primers are used with 4350 powder.

Paging through my Hornady #7 manual the first magnum primer I find being used is for the 257 Weatherby magnum and that case holds over 60 grains.

Is this for hunting or competition?

This would be for targets and some competition.

This is an interesting discussion on primers. I recall talking with a custom action maker, who shall remain anonymous, about loading for the 6br and I asked which primer is best. His answer was "Whatever lights the fire!" With that being said, there alot of guys using cci 450 magnum primers loading for the 6br and it isn't because the powder charge is massive. It's because they have a tougher cup and are more consistent! I know another old timer that all he uses are magnum primers loading for .260 Rem and .308 Win! It's whatever works best for you!

Thanks,
Mike

Really like all the answers you are getting.

In summation they basically say what I would say - "It's all right if you like it"

Try and you will find out. There are no rules "in stone" on this issue.

I use Federal Match Primers for my 6.5 loading IMR 4350 and it works really good for me while shooting paper.

Use the mildest primer that will give low ES numbers. Russian and CCI are generally the mildest. With a large powder charge, a little hotter primer may be needed. Remington and Federal are on the hot side. There should be no need for a magnum primer in your application.
