IIRC, the Lee Internet site has up-to-date the list about which primers are ok to use. They now seem to one out FEDERAL precisely:
Insert to estimate Only clearly show this user #three · Oct 2, 2006 The one thing diverse in between the two will be the name. The Federal's Can be just an exceedingly slight touch hotter, but question severely if you will find enough variance to worry about. I've applied equally interchangeably and in no way experienced a problem.
Have also browse the Federal primer warning in Lee's 2nd ed. handbook, and am guilty of utilizing the Lee automobile-primary tool to seat them. It really is kind of frustrating the warning does not make clear why the CCI's are Harmless and also the Fed's will not be.
These adjustments in "blend" do make an exceptionally slight difference in primer functionality but is so negligible that it makes primers "common", assuming you Examine precisely the same kinds.
Centerfire rifles are inclined to obtain much more firing pin energy. I've had Federals rupture but never Winchesters or CCIs. I Particularly like CCI small rifle primers when loading for ARs. Their harder cups tend to be more immune to slam fires.
This can be an older thread, you might not receive a response, and could be reviving an old thread. Remember to take into account making a new thread.
If I'll, your understanding is incorrect. There is absolutely no these types of thing a 'hard' or 'gentle' primers. Mil spec primers are magnum grade and fewer delicate towards the firing pin strike.
(I'd only mentioned which i was having to use plenty of tension around the manage to seat primers in commercial cases.)
Incorporate to estimate Only show this person #eighty four · Dec 22, 2023 We experienced a shortage before the war in the Ukraine started off. We've experienced other wars prior to now. This long scarcity and also the exorbitant costs on what's offered certainly 210m federal primers are a new phenomenon.
Never to hijack this thread but a buddy of mine that creates ammunition suggests the Federal 210M primer. Why, I have no idea as he was attempting not to provide me proprietary details. I'll use the Lee Hand Priming Device Once i get all around to using the Feds. Ken, the box is baaaaad.
My guns are extremely exact and i have had no hassle. I do recommending Operating up masses equally as you'd probably any new load.
Personally, I use 210M’s or 215M’s After i go searching, with regards to the cartridge. It presents me assurance. But I don’t know in case you’d ever see a measurable difference between the two. Primers are certainly one of the cheapest elements we invest in, but might be critical to constant muzzle velocities … so I generally don’t check out to save what only amounts to several pennies for every round by selecting a standard primer over a match primer.
Now as for that caution not to employ Federal primers in Lee instruments Here's The main reason for it. If you employ plenty of Federal primers you can detect a lime inexperienced residue Establish up from the primer flip tray.
If firing pin energy is at or previously mentioned the edge, the primer will detonate reliably and create the utmost intended ignition price. Stage is ... primer flash will not be at its entire possible until eventually firing pin Electricity fulfills or exceeds the sensitivity threshold. With rifles, This is certainly rarely a problem due to the fact there is usually an extremely robust firing pin strike. Armed service rifle ammo has "desensitized" primers to forestall slam fires but most primers designed for the civilian industry will not be desensitized.
