Converting a Browning BLR Lightweight '81 Takedown

Hi Forum,

I would like to know if it is possible to convert a Browning BLR Lightweight '81 Takedown in .300WSM to 510WSM?
Essentially, the 510WSM is a subsonic round using a .51 caliber bullet inside a 300WSM case that's cut off at the shoulder to 1.665", with an overall length of about 3.350". Assuming the bolt face will stay the same, will the round feed and chamber from the magazine? Or is this just too long of an overall length?

Here is more info on the 510WSM: ... rint_topic

Kind Regards,

Looks pretty straight forward. A mate has an BLR takedown convert to 416 Ruger and it works well. Thou muzzle blast with the brake is ridiculous.

Only issue I can see is if you want to load up flat nose proj as they will catch on the back of the chamber

Pointed monks like the one picture should work fine.

I had a big bore wssm and it was a hoot but also a pain due to not feeding half the projectiles I would have liked to use
