H414- Should I Be Using Magnum Primers ???

[robbobsam]

I have been using H414 on some home loads with some mixed results, I mentioned this whilst at Norman Clarkes (Local Top Draw Gunsmith) and was told I should be using Magnum primers on H414 as its a ball type powder.

Has anyone else in here had mixed bags using H414 without magnum primers ???

Can anyone recommend a primer they have had good reSults with on H414 ???

I use 414 in my 243, 260, and 7-08, all with standard 210's.

I have always used CCI 250s with H414 most loads in 243 and 25-06.

In a 243 Ackely, I use 200's. I tried 250's because of a hang-fire and the ES was all over the place. I went back to 200's and haven't had another hang-fire and nice ES again.

I've used CCI 200s in my 30-06; with good results in winter with a hottish load. When it gets above 32 degrees F, the powder gets too temperature sensitive so I switch to IMR 4831.

i was told 20 years ago to use a magnum primer for ball powders which 414 is so i do and actually i shoot a magnum primer out of everything except 223 of course. also i only have to buy one kind of primers.

Is there a down side to using Magnum Primers for everything?

I started using magnum primers in my .308. Seems to work well. To answer the question above. There is nothing wrong with using mag primers in everything. You just have to adjust powder combos a little to match up. A max load in a manual will be a little lower when using a mag primer.

Lapua sells 308 brass with the small rifle primer. I believe it also has a smaller primer hole. This is for the target shooters who need premium accuracy. So the way I see it is that a hotter than necessary primer might mess with accuracy, SD and/or ES.

That is a good point and I am inclined to agree with your line of thought.
