Magnum Primers Needed for H335?

[Classic]

I am loading 5.56 and plan to use H335 powder with a 55 gr. FMJBT. I have consulted several manuals and some say a SR magnum primer is necessary, some do not mention it. Anyone have any experience with this issue?

 

[Yeah]

Only Powder Valley's customer service department could even hint at how many 8lb cans of H335 I've burned, but it is a bunch and I've never done it with a magnum primer. CCI 400s have done it all.

I've had the same experience. I've used both CCi 400s and the older Winchester WSMs with the silver cups with no problems. Since I load mainly for an AR now, I've switched to the CCI 41 but not because of any problem with the CCI 400s.

I have always used regular small rifle primers in my 223's. Mostly WSR with H335, H4895 and AA2230 with no problems.

Regular primers are all I have ever used behind 335 and I have never had a problem.

Standard primers will be fine.

You can use either no problems,consistant ignition is important,thatswhy I DO use mag primers in 223 & find it has better accurasy.

Thanks for all the input. Appreciate everyone taking a minute to respond.

I load H335 for both the .223 and .30-30 and I have never used magnum primers. Standard CCI and WW primers have worked fine.
