20BR / big 20

[Scooby-93]

Hi all,

I’m looking at a high capacity 20 cal, in particular the 20br.

i have a tikka T3 to use as a donor, has anyone gone this root and had reliable feeding from the mag?

alternatively I am thinking 20-250 or 20x47.

i think the 20-250 will be easier than the 20x47 in making brass but I like the idea of the small primer in the 47 case.

anyone with any of these calibres could you please share your experiences 

Im wanting to shoot the 55gr Berger

I used to shoot a 22BR and still shoot a 6BR, you will get reliable feeding if you use AI mags converted to feed the BR case.

Hi Justin, 

is this with a t3 action and is that 1 of daves converted mags or another smiths?

T3 with modified AICS mags should be fine, my 6BRA feeds flawlessly, even with the 40deg shoulder.

Yes a t3 and yes it’s one of Dave’s converted mags.

There is still plenty stock in the uk to keep me going, certainly enough to last the barrel life

That's good.  

My mate is using one of the new Mdt 6mmbr mags in his Remmy action 6mmbr rifle and it feeds well so they should be ok for the 20br as well

That sounds promising 👍🏻 I think they only do a 12 round mag shame it wasn’t a 5 but it could be a option
