Magnum primers are recommended for the .204 in all the loading manuals I have ever seen (six different manufacturers' manuals) |

would it be safe to assume that the start load would be safe with a magnum primer? i.e. this is according to berger's load chart for thier bullet 40gr Berger BT (bullet) ruger 204 H414 powder start load 26.0 gr (safe to use magnum primer starting here)? Max load 28.8 gr |

While I strongly agree that magnum primers should not normally be used in non-magnum cartridges, as with most things there are a few exceptions. One of these is when using ball or spherical powders. These powders usually have a heavier protective coating than "stick" or "short-cut" powders and often give inconsistent ignition, particularly in cold weather. It should be up to the individual to conduct "due diligence" and research the powders with which they are working to see if this is a fit for their application. And, as always, if making a change to magnum primers, be sure to reduce the load and carefully work up. |

Hey MacD I use magum primers in both my 22-250 and 308 loads WHEN I am hunting in 0 degree F or below weather. I have found that using the magum primers in warm weather throws my accuracy right out the window. And as I am in brisk old Saskatchewan, I have had plenty of experience with the benefits of mag primers. |

Here was my thought and I could be all wet... but I have "heard" in the 204 partially compressed loads preform better with a magnum primer and that the 204 seems to just like partially compressed loads. So I specifically started working with a load that once worked up to max (as long as no over pressure signs where present) would end in a 100% plus fill ratio. My current test loads are with the standard CCI 400 primer. With that in mind I was thinking that a magnum primer would work better to fully ignite all the powder, thus giving better performance... Am I on the right track? FYI, I will also be testing the 35gr Berger and the 32gr Hornady V-max Thanks Dave |
