They don't change burn rate of the powder, just add a little pressure to a a cartridge that may be near maximum as it is.They are a "hotter" primer, designed to ignite the larger capacity loads in the magnum cartridges. They will work, just be sure that you work your load up. They can change the burn rate of your powder, so work up and watch for pressure just as you would when changing any component.
Its POSSIBLE to use a FEDERAL 215, which is a MAGNUM PRIMER in place of a Federal 210, BUT WITH EXTREME CAUTION! The 215 will IGNITE the powder charge COMPLETELY in the CASE, instead of a COMPLETE BURN down the BARREL. SLOWER Burning powders as Hogdon 4831 can be used SAFELY with REDUCED LOADS! ALSO, when doing this YOU'RE BREAKING the RULES OF SAFE HANDLOADING & MUST PROCEED WITH EXTREME CAUTION! MEANING you MUST BE EXTREMELY AWARE or TEMPERATURE WHEN FIRING THESE LOADS! There are NO PROVEN SAFE GUIDELINES or MANUELS to show you MINIMUM to MAXIMUM Charge weights! Therefore its NOT IF AN ACCIDENT HAPPENS, IT'S WHEN IT HAPPENS and IT WILL, YOU have NO ONE to FAULT, BUT YOURSELF! I'd STRONGLY RECOMMEND NOT DOING IT! TheosmithjrHave no Federal 210 on hand, have a ton of 215 specifically GM215M. I use them for my 300 RUM. Can I use them for my 30-06, 243, and 7-08? Thanks.
We're already publishing that book, "Long Range Hunting On Line!"Very good topic with many meaningful insights to the issues of 210 to 215 primers or any standard to magnum combo. I take the most of this from a perspective of SHTF or the more likely I don't have income any and still have to shoot and reload with what I have. Mabey we should get to together and write a non-conventional loading manual all safe loads with no legal basis. It could be put out as an information guide line only and not as a preferred method of reference. Just thoughts some day may come when we no longer have the components we love or prefer or we may run into the legal means to buy any more.
