6br necked down
It is the 6mm BR Remington necked down to 224. It wiil shoot a 40 gr at 4000fps or the 55gr at 3600+. It is a very accurate varmint round and a very good one.
But if it were me I'd get the 6x47 Lapua. Which is the 6.5x47 Lapua necked down to 6mm. This is a better mid range varmint round with a slow twist and light bullets and a better long range round with fast twist, long barrel, and heavy bullets. I would love to have the slow twist in a light carry varminter and the fast twist in a heavy long range rig. The 6x47L is highly accurate, fast enough, and has long barrel life. I think it will be a very popular round going forward.
