Thanks Kirby, I am just trying to inform those who might be interested in a rifle like this. I am just reporting the info from the guys who are using this set up. It seems to be performing very well out to 800 yards with this bullet.
I am going to make my 300 Varminter into a switch barrel set up, so when I shoot past 1000 yards, I can switch over to using a Krieger 30", 1-11 twist barrel using the 208grn A-Max. This will save me a little money down the road.
Anyhow, It sounds like your 375 Allen Mag is performing well. Look forward to hearing more about it.
