20-250 or 20 dasher info?

[hammerdown22]

does anyone have any experience with either of these?
I have 2 bartlein 20cal 9 twist barrels, 1000 50gr, and 1000 55gr berger bullets.
I want to build a long range 20 cal and trying to decide on a chamber.

I built a 20-250 years ago. My goal was to get 20BR velocities but feed slick from the mag. It worked. Ended up with Varget as the powder

I played with 20BR for a few years. I built with a 10 twist barrel to shoot Berger 50's. Then Berger quit making 50's. 55's don't work in a 10 twist. When I tried 39 Sierra bullets they disintegrate at 4200 fps so I went to 40 vmax and shot them at 4500fps. I shot some 800+ yard prairie dogs.
I constantly struggled with forming brass and working up good loads.
Next step was a 20-250 in a 9twist. I love it! Easy brass forming, feeds well if I want to use it for coyote and not too picky working up loads. It shoots the Bergers real well but really shines with custom made 48 and 50 grain bullets. I have 3 rifles in 20-250.

I have a 20BR, sitting neglected and wanting attention. I went with a Shilen select match 1-9" twist, 55 Berger's I hope will fly.

At AS there is a discussion on the 20 Dasher or BRA.

I've got a weatherby vanguard 22-250, and I load 55 gr nosler ballistic tips with 38.0 gr h380 powder and can touch holes on paper, it's a tack driver on coyotes too.
