.20 Cal Berger 55gr, any one using?

[L.Sherm]

I know where you can get some custom 55's that shoot well if anybody is interested. I've shot them and they are just as good as Bergers.

I did not read every post. Sorry. I shot 55 Bergers out of a 9 twist and a 8.5 twist with zero problems. That being said the 55 Berger is on its death bed. I could not get faster with 39s in a 20br than I could in a 204r. I think that case thrives with large bulelts. I was seeing some great results with Black Hole Bullets 55 gr when I let my 20BRs go. One barrel liked RL17 the other RL15.

Thanks for your observations rfurman24. I too found that I can push 40g and 39gr bullets in the .204 Ruger with a 26 inch barrel, just as fast as in the .20 BR. I will get hold of Black Hole and purchase some of their bullets. Reloader 17 was a winner for me with the 55 gr Berger. I tried VV N-550 (my second choice), IMR 4451 and from Alliant 2000MR and Reloader 16. I am curious about the Black Hole bullets. What can you say about them?

I was not done with load development but they were shooting under .5moa already. I had the Bergers shooting in the .3-.4 at 100 and staying under .5 out to 500(farthest I shot them on targets). They buck the wind like crazy but offer little splat on prairie dogs if that is your thing. I tried h4340, big game, rl 17, rl15, varget, and 8208.

I shoot 55's in a 9tw with zero problems out to 500 yards at 3750Fps in a 20 BRAI using RL15.
In my opinion you gotta have a BR or 250 type case to take advantage of the 55's longe range capability.

You must be standing on the gas pretty hard if you're getting that kind of speed from the 55's in 20BR improved and RL15

Nope I'm not, worked up to this node shot so well I stopped.

 

[L.Sherm]

Just a little over 31.0 of RL15

 

[L.Sherm]

I tested some custom 46.5gr custom bullets from the same guy who's 55's I switched to at 4050 Fps

I have been impressed with the velocity from the 55gr (HBN coated) Bergers with Reloader 17. 31.0 gr will give me just over 3600 fps (28 inch barrel) and the pressure is mild enough I only half neck size, as designed, with a Wilson neck die. No body swell.

That is why the 40 gr bullets are not as impressive from the .20 BR at under 3900 fps.
