Prwlr,

The Federal 205 isn't the mildest and softest-cupped small-rifle primer, but it's definitely toward that end of the spectrum. It's primarily meant for relatively small charges of the small-grain extruded powders favored by most short-range benchrest shooters, which are easier to ignite than spherical powders like Li'l Gun and 300 MP. In a test I ran on different primers in the .22 Hornet a few years ago, the F205m resulted in by far the slowest muzzle velocities and widest velocity variations with Li'l Gun.

JB, do you think CCI 450's would do a better job igniting 300MP, versus BR4's?

Tex,

Not JB, but I think I can summarize; JB can correct me.

The hotter primers, like 7 1/2, BR-4, 450 do a better job igniting slow burning powders like Lil gun and 300-MP, with 450's edging others for top spot.

Gunner agrees with that, so I guess it doesn't matter what JB thinks... shocked

It's not supposed to work but Winchester small pistol primers are the best I've tried in my hornet.

No tube, using a cheap lee kit and throwing the charge in the top. fills the case up almost to the top. I'm almost convinced I could just dip cases, strike off at the top and seat a bullet.

The K Hornet case definitely has more room. 13 gr. drops in with room for the bullet.

I've not had issues seating but its definitely compressed. Standard has been good to me, K doesn't intrest me much.

Would like to hear more about your tests!

Nothing elaborate. I started with Remington 6 1/2s and was getting groups 1.5-1.75". Tried CCI small rifles and got the same. Read about small pistol primers and all I had was winchesters in stock. Groups immediately shrunk at least in half and best groups are now running around 1/2". Nothing else was changed but primers.

How many shots in a group? Did you check your handloads for bullet run-out?

LOL, think I'm getting in 13.5 grs with only neck sizing about 1/3rd inch of the neck or measured bullet shank in the case, can't remember the exact number, but size die is set to do so. smile

That's why I started and finished with the 450 mag primers, I knew early on I'd be trying to ignite a heavily compressed pellet of lil-gun,cool I need HEAT and a tough cup Man. lol

There's also a difference in how much different kinds of brass will hold. Prvi cases are heavier, with less capacity than the Winchester cases I mostly use.
