35 Remington Primers

[tipiguy]

I saw in the Sierra reloading manual that they recommend Federal 215 primers for contender 35 Remington loads.  Federal 215 primers are for a large rifle magnum.  Anyone else using Federal 215 primers?  I can't find any of the other bullet manufacturers that recommend them.   Any ideas why they recommend mag primers?

All I can think of is to look at the powder, is it at the slower end? If not it very well may be a typo. I cannot think of an edition or writer that doesn't have one or two.

Sierra has recommended using F215 primers in .35 Remington handgun loads for several decades - this is not a typo.  Based on their recommendation I used the hot Federal primers for years, then several years ago I switched to F210 primers and saw little difference - I found I could use slightly heavier charges, got slightly better accuracy, and saved a little money.  

I'm not certain why Sierra recommends the hot primers in handgun loads when the same case in rifles uses standard primers.  Sierra loads for 7-08 and .308 handguns (with much slower powders) use standard primers too.  I see no good reason to use them now, based on my own extensive experiments.  BTW, almost all their .35 data seems to be 20+ years old; perhaps if they revisited their listed loads they would change their primer recommendation.

You may also find that alot of manuals will use mag. primers anytime a ball powder is used ... even if companies like accurate recommend against it.... Some old geezer lost in the 60's? Or some kind of safety policy???  At any rate The only load I ever had that changed much between mag and standard primers was a max load (by the book) of 1680 in my 357 Herrett that did NOT want no Mag. Primers .... Made a Pressure difference.. as for accuracy in almost all circumstances regular primers are preferred unless you are loading one of the "big" weatherbys ... they like Mag Primers.       Marty

This doesn't apply here, none of the powders are spherical.  And the .35 Remington rifle data lists some ball powders but uses Remington 9 1/2 primers - among the mildest made - for everything.  They recommend F210 primers for a case full of H380 in the .30-06 hangun data.  In fact, no other bottlenecked handgun data for large primer cases uses magnum priimers.....except for the .357 Herrett.  Very odd indeed.

I concur .. that is very perplexng...might just get curious enough to call .... Marty

Thanks for the help.  I'll stay with standard primers.

I used H322 and loaded some with mag primers and others with standard - AFTER WORKING UP EACH LOAD.   I was using CCI primers.  Then I did the same with H380.  There was no difference with my loads that I could visibly tell.  I never Chrono'ed any of them - that could have produced a velocity difference?  I did chrono the standard primer load and it flew the same fps that the manual was stating.  

Some manufacturers do recommend the mag primers with ball powder, but being in the South where temps are mild, my loads do just as well with the standard primers.
