can't recall what the twist is of my 7 Mashburn tube, this is my 3rd one and they've all been the same but can't recall...
I couldn't get Bergers to shoot in this barrel but then again I've yet to get them to perk in any of the cals that I run....?
With the 175's I run R25 and with my 25" barrel I can push them to 3100, but prefer to run them a bit less. 3K-3050 seems a bit better to me in this barrel.
I've found I can run the 160's to 3300 but that's leaning on it awfully hard. Lot of powder depending I normally run them tween 3150-3200 on the top end. 7828 is the powder I use with 150's-160's.
My fire form load I've used for all 3 tubes is IMR 4350 with a 139 Horn flat base, it runs @ 3250 and is wicked accurate!!
4 me, it's a fun round. I was fortunate to know Hagel and called him a friend and that's why I run it.
If you've never read "One Mans Wilderness" by Page you should it's one of the greats!
