20BR or 22BR

[Browning442]

Which with a 20 Br is not a ton!

I “had” a 22BR… limited yardage with any bullet-… well, I did shoot a bunch of varmints Fromm 100yds-300yds..Seems the 53gr Vmax was the best bullet I found in mine…LIMITED case capacity for competition, hence the 22DASHER set a record, by James Phillips..

My 20BRAI is a different animal.
The 55gr Berger bullets running 3650-3750fps, is a laser.
I’ve even cared it to 600YD competition and whooped some 6mm butt.!!! It agg a 1.98” in LG on 4 targets.
Stan Taylor & His boss set some Range records w/ a 20 Dasher….shooting there 56gr bullets
VolDoc carried his SAVAGE 20BR with 55gr Berger, to shoot prairie dogs out west, I believe it was close to 1100yds with a kill, memory slips me…
Terry Balding shoots his in every competition, and hunting adventures he goes on..
I’ve yet to set a barrel back, and clean after 22 to 25rds..
those are my thoughts.. I think the 20Dasher is over bore, the 20BR hitting the sweet spot, 20BRAI- best of both…
22BR, not ever again…..

This just my experience….

Well if a 20 BRAI would be better why not 22 BRAI for heavier bullet and longer range?
The OP said he wanted to stick with the BR case though.

 

[Gabe22BR]

Haven’t seen one in action….

In theory it should , that 1.5gr the dasher holds over the BRAI , might be the key…????

The B.C of the 20 cal. 55 is were it shines, not that B.C is everything but in this case its a laser. I think you would have to get up to the 90 in a 22 cal to get close.

What barrels are you running and what are the twist?

 

[Gabe22BR]

Kreiger Muller works 1-9

I've decided to go with a 20BR . I have had a couple Dashers, several 6BRs and a couple 22BRs so why not try a 20 ?

 

[AlNyhus]

A 20BR with the BIB 40 gr. bullet is pretty impressive. A .290 B.C. @ 4,000 fps is almost like cheating. Adjust to your probable velocity and run the numbers on drop over your likely shooting distance and compare that to the 55's before committing. The 11 twist barrels are perfect for anything but the 55's.

Good shootin' -Al

I've had several 20BR's through the years. All 1:9 twist Bartlein or Kriegers HV on custom actions set-up for the Berger 55 gr. They are easy to tune and very accurate at the longer ranges. Most barrels last 900-1000 rds. Had one that went 1500 rds.

Should make a dandy XP-100 long range pistol. I'd like a XP-100 pistol in 20PPC, but XP's are becoming more difficult to find at a reasonable price as a donor action.

Best of luck on your upcoming build.

I wonder how those 40's would hold up in a 9 twist?
I tested some 46 gr bullets in my 9 tw 20BRA at 4050 and they did fine. I didn't even run it up pressure to see if there was a higher node just shot really well there and stopped.

I did some testing last week with the 40BIB

The 20-221AI 1-8” barrel. loved them!!!
20BRAI. 1-9” not so much.. they’re barely in the case neck. I got’m to 3917fps using the same load as the 55grs, keeping the base of the bullet the same as the 55gr base in the case..

They’re best used a Varmint bullets as they are designed to be… I guess that’s why the little 20-221AI punched a single hole …

What powders are you guys running in the 20BR and 55’s?

 

[Gabe22BR]

203B/RL15. Is my best load density / accurate powder.. I’ve tried a lot of different BR powders, & wild powders..

Absolutely gorgeous SP in a great cartridge.

My 20 BRA loves RL15 like Gabe with the 55's. I tried RL16 wouldnt go anywhere as far as velocity no matter how much powder I put in the case.
If I can get my hands on a lb of 15.5 ill have to give it a better try, when it first came out took .2 more gr to achieve same velocity as 15.

I've had a XP for sale for a while with very little interest so I'm considering a rebarrel to something else I would enjoy shooting. My favorite XP I have owned was a 22BR slow twist shooting 52 gr bullets. My thoughts now is a fast twist 22 BR or 20BR to have a little more range than the 52's had . Any thoughts on these two in an XP platform will be appreciated.

I put together a custom 22 Dasher and it is amazing. I cannot say enough good things about the new Berger 85.5 gr Hybrid Target!!! There is alot of work in making brass from the Lapua 6 BR brass however, I bought a box of Alpha 6 Dasher brass that I will neck down and turn.

-Krieger 7.5 twist at 21 inches
-Lapua brass
-Wolf Small Rifle Magnum
-2930 FPS single digit ES
-34.3 H4350
- .022 off
I am capable of running to 3100 without pressure; all the accuracy and precision is between 2900 and 3000 with the Berger.

Worked up loads with 80 gr SMK and 80 gr Nosler Competition J4 that were no comparison to the Berger, wasted components and barrel life because I couldn't source the Berger bullet that my reamer was based on.

Attached are some loaded rounds and a nice 5 shot 500 yard group.

This little Dasher amazes me and I regret not getting into one sooner.
