Hello All,
Thanks for the reply.

Here is a quote from a man on a different forum ...

"... A great caliber that suffered the ignorance of the shooting world in its day.. They produced the wrong bullet that continued to fail and blamed the caliber as we still do at times..

I hunted Buffalo and Plains game with it some years ago.. the good Hornerber brass was available and good Woodleigh 347, 350 and 400 gr. bullets were abundant.. The 347 and 350 got me 2300 plus a good bit, and the 400s were good for 2100 to 2200.. Worked on Buffalo and PG just fine and gave you an extra round in a good 98 Mauser with 5 down in mine and one up the tube...."
