I'm new to the 5mm round and I've been researching like crazy to get caught up on it's capabilities. Just acquired the gun last year and finally got it cleaned up and put back together recently. I'll be putting on a scope this week I hope and will be ready to put it to work soon.
Ok a couple questions...
1) what was this round meant for? i'm guessing varmints and coyotes mainly
2) what type of round would be preferred for coyotes, the JHP or SJHP? I ordered several boxes of both types of ammo but have a feeling i'll be using the JHP mainly...unless the SJHP is more accurate but I would assume they would be comparable.
In my area back when the caliber was rolled out it was a better choice over 22 magnum for ground hogs.
The gap has narrowed a bit now since better bullets and more choices weight wose are available for 22 magnum.
5mm is balisticallly superior on paper as far as ballistic coefficiency and wind effects.
The round back when didn't garner a good liking overall due to being metric caliber. Americans the 7 mm magnum did a lot better interest wise later on.
Seems the 6.5 creedmore has huge interest. Lower recoil yet can run trajectory wise with the magnum. Hence the grand 300 magnum is for all practical purposes history.
The 6mm suffered too back when for same reasons as 5 mm did.
It is superior round to 243 Winchester, but folks just wouldn't bite on the metric caliber.
Younger generations are far more interested in metric calibers.
They are not looked upon as old balls like yesteryear.
Notice the 204 ruger was not deemed or called a 5mm.
I don't think this is no accident.
I think Hornady and ruger were afraid if they called it a 5mm it may have suffered with interest.
So far seems it is popular so maybe they did the right thing calling it a ruger 204.
