Is anyone reloading for this cartridge?  What powders and what bullets do you have experience with? How has the cartridge performed as a varminter?

Denver Steve

I have one in a cz527
Phenomenal cartridge for varmints.
The 35 grain Berger bullet is my favortie. It is a flat base design and seems to work the best on coyotes/foxes. I have used the 32 grain vmax and nosler varmageddon. The varmageddon I would give the edge to. I also have used the 40 grain Berger with good success out to some extreme ranges.

Mine likes H4895 powder the best. XBR8208 and H322 are great performers as well. If you want the most speed CFE223, TAC and Leverevolution are the top but at the price of temp sensitivity.

Basically any powder in the H322 to Leverevolution burn range will work. The go to "bench rest" powders seem to do the best and most consistent. I have heard great things about Varget in the cartridge, especially shooting bullets on the heavier end.

What would you say is the max reliable distance with the 40 gr Berger. Will it do prairie dogs at 500 on a tuned load with minimal wind?

Its funny you have brought up the 204 ruger.. i have been shooting a little howa mini action 204 ruger the last two days.. i shoot the 39gr blitztking out of this rifle with rl15 for powder.. great varmint round inside 400 yards.. killed 4 coyotes with it from a 100 yards to 350 yards and they all dropped dead in their tracks.. i had a 24 inch savage barrel screwed on and shot the 40 gr v-max in it with h4895 and it was a laser.  Still got the barrel just dont have it screwed into anything at the moment.. cool little round.. tedious to load but fun to shoot..

Its possible jerry but that would be pushing its limits in my opinion.. its really losing steam out there.. which the higher elevations your at would help that some ..

A little data from my applied balistic app. 
At 3800 fps with a 40 gr. Vmax and a 100 yard zero. Its dropping 7.5 minutes at 500 yards with a muzzle velocity of 1800 fps. With a 5 mph cross wind it needs 3.5 minutes of correction.. at 500 its carrying 294 ft. # of energy..

Similar results from Ballistic Arc.

The Berger 40 has a lower BC and not as good of results.

I like shooting this cartridge.   I use CFE-223 for powder with 32g SBKs.  MV is beyond the range of the Labradar.  Have shot it out to 300 yards with really good results.   I have a Savage 12 LPV with a factory 26" barrel.   I am in the process of putting a 26" Krieger barrel on a Browning X-Bolt.

It will be able to do that. You won't get as explosive results as you would at closer ranges. Starting to push the envelope at 500 where the bullets opens up nicely.
I have hit and killed a coyote at 700 yards with the 40 grain Berger and the bullet just pencil holed in and out. It killed it, a bit delayed though and a bit too far. I have had good results up to 450 yards on coyotes though.

This caliber gave me an excuse to build another AR15 platform! I'm only shooting factory loads (Federal/Nosler 40gr ballistic tips. Chronographed them on my LabRadar at just under 3,700FPS. (Barrel is a White Oak Armory 26" H. Varmint barrel). This rifle is a hammer, but it is pure hell as far as copper fowling. All that said, I would not said hesitate taking pokes out to 600+ yards on a calm day with this set-up!    8)
Yes, I realize speling is a chalunge for sum of us...I am inkluded in that grup, so pleze fourgiv me. Ski-U-Mah!

I had an opportunity to pick up a M77. It's a 1:12 twist which makes me concerned about pushing a 40 gr bullet.

gman47564

That would make you a nice rifle jerry.. the 1 and 12 twist will handle the 40 gr. V-max just fine..

Looked at the Berger Stability  Calculator with the 40 gr Berger using a 1:12 twist at 5000 ft altitude and 3600 fps MV. It said - not stable. I'll go back and look at it again to make sure I put in the right numbers.

jvw2008

Repeat calculation is 1.32 marginal stability.
