Hi all- first time poster here... I "inherited" smome various reloading supplies from a relative. Among the loot was a box of 1000 Winchester Large Rifle Magnum Primers. I do quite a bit of reloading / tinkering with 30-06, mainly with IMR 4350 and 4064 for my Model 70 and 7400 carbine. Is it safe to use the magnum primers with my IMR? Anybody already done that experiment? "Dyin' ain't much of a livin" | ||

I’ve used mag primers in 308 win although both accuracy and velocity suffered. The only exception to the rule I have seen was with a well compressed charge and CCI mag primers. If you “must†burn them start with the min charge and work it up SLOW. Sic Semper Tyrannis | |||

WOW that's pretty fascinating, should have new respect for trying different primers. Those remingtons were really hot! | |||

Absolutely.....just work up as usual. /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery." Winston Churchill | |||

You'll likely find little difference between WLRs and WLRMs, particularly in a case as large as .30-06. As Vapodog says, work up just as you would with any load. | |||

Not that I don't find the photos of primer flashes that Rex Rat posted interesting, but looking at the flash is like looking at the light produced by a light bulb and inferring how hot the bulb is or the amount of electricity going through it. To some extent there may be a correlation, but it is doubtful that it is in linear proportion to the apparent "flash". The actual energy produced by the primer and its effect on the perfomance of a given load cannot so easily be inferred. | |||

I use magnum rifle primers in all my '06 length & 308 length brass that use ball powder. Been doing it for years. Somewhere along time ago I was told that ball powders can be hard to ignite in cold weather. Whether true or not it became a practice with me and I still do it to this day with good results.

My Sauer 202 has 7x64 and .30-06 bbls. Both average <.75 MOA with Sierra GK and N 160 powder : 7x64 : 160 GK / N 160 / 56.0 (CCI 250 primers ! NB. : std. primers produce vertical stringing); .30-06 : 165 GK / N 160 / 60.5 (WLR std. primers for nice, round groups). I'm not more surprised than that as I'm a firm believer that each rifle/bbl. is a law upon itself.

I was think that too. And duration is an issue that may make flashes look "bigger" when they just last longer. But the larger particles burning in the Remington & RWS samples were a surprise. Looks like a really different design philosophy than the others. "Experience" is the only class you take where the exam comes before the lesson. | |||
