Mostly interested in Nosler 260's and various 300 grain bullets. Thanks I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally

The 92 grain charge will shoot under an inch for three in calm winds, haven't hit anything BIG with it yet but should be very predictable out to 400 long yards. Trump Won!

The Dave Manson reamer is a .375" freebore. Really? Looking at PT&G's book of chamber prints for the .375 Weatherby, the parallel portion of the freebore is 0.735" long. If we consider the parallel portion and the gentle 1*-19-0 entry into the rifling it is 0.996" long. Looking at PT&G's chamber print for the .375 Ackley Mag. Improved it shows 0.200" long. Please note: I did not say the .375 Weatherby was "based" on a long freebore, I stated the data in Alphin's book Any Shot You Want would have been collected from a test barrel using a .375 Weatherby reamer, thus "assuming" a long freebore/parallel throat (whatever you want to call it).

Ringman Campfire Ranger Joined: Nov 2003 Posts: 28,834 Grants Pass,OR	If a .375-.416 Rem Mag is the same as a .375 AI then I have a few loads. This rifle has a 28" barrel. All use Federal 215 Magnum primers. These loads regularly make groups under 1 1/2 inch at 100; often way under. The Barnes TTSX 250's go under 3/4" all the time. All these are accuracy/hunting loads. Of course they are the highest velocity accuracy loads I could get. Sierra 300 - IMR4350 @ 87.0- 2,700 feet per second Sierra 300 - RL22 @ 98.0 - 2,918 fps GSCustom 265HV - IMR4320 - 83.0 - 3,055 fps GSCustom 265HV - IMR4064 - 83.0 - 3,034 fps Barnes TSX 270 - IMR4320 @ 84.0 - 2,987 fps Barnes TSX 270 - H4350 @ 89.0 - 2,875 fps Nosler 260 - H4350 - 89.5 - 2,976 fps Nosler 260 - Varget - 82.0 - 2,983 fps Barnes 250 - IMR4320 - 84.0 - 3,098 fps These are smokin' hot for accuracy!
