20BR barrel length

[Sharpshooter243]

I've decided to build a 20BR with the savage 510 I've picked up. What barrel length should I go with to make sure I'm getting decent performance out of the cartridge?

I've been thinking the 14-16" will be fine but would 18" be worth the extra weight. I plan to keep it center grip at this point and a light varmint contour

I run a 26" on my 20BRAI. Every body I know who runs a BR case uses a 26-28"

 

[Ernie]

Mine is a 15 inch barrel, and I shoot a 55 grain Berger at 3173 fps using Varget.
14-16" would be great.
I have shot steel with it past 1000 yards.
This picture was taken at a PRS match about a year and a half ago outside of Sheridan Wyoming. It was kind of fun shooting a single shot XP against rifles

Does Berger still make the 55gr in 20 cal?

Does Berger still make the 55gr in 20 cal?

To my knowledge, they quit making them, but I was fortunate to get a good stash

 

[L.Sherm]

They still do 1 run a year through Grafs, they have them now.
I run the 55's in my BRAI at 3750
I've tested some custom 46grains for a guy at 4050 all in a 9 twist.

This is great to know-Thanks!

What's the average barrel life for a 20BR?

 

[L.Sherm]

Not sure ive heard 800 - 1000.
I've only got about 200 on mine.
A mod 400 steel from Bartlien i would really consider.

 

[Ernie]

Don't know...I have 400-500 on mine so far. Only shooting the 55's though...More bullet, slightly less powder.
Mine is a McGowen 8T

 

[L.Sherm]

I do know one thing, mine is a laser.
Would be a coyote killing machine with the 55's.
There is a couple guys who shoot the 20BRAI in 600 BR that do pretty well.
I know one guy who shot his at 1,000 BR and it was 3.5"+

 

[L.Sherm]

25.6" drop at 500 is pretty good, with a 200 yard zero.
29.1 with a 100 and sea level

 

[Ernie]

6.9 MOA or or 36.1" of drop for 500 yards (20BR with 8T 15" barrel).
Mine is NOT a AI

I was probably going to have McGowen do mine as well but I am hoping for 1000-1500 rounds of life shooting 40gr Vmax's but may have to get some 55's while they are available.
