The reason I have the limit of 600 yards is because that is how long we can practice at. The range we use has a very good setup. You can shoot 100, 200, 300, 600 yards.
Thanks for the input guys.
I have an LTR in 300 SAUM and am pushing the 180 Ballistic Tip to an AV of 2814 fps using 62.0 grains of IMR4350 in Rem brass and lit by a Win large mag primer.......that's out of a 20" barrel.
Can't see putting a heavier barrel on a magnum Model 7.....they already have the Remington magnum contour barrel......
I have a Model 7 in 7 SAUM in an HS Precision stock......I had to open the barrel channel for the mag contour barrel and it fits like a glove!! Don't think you can get too much heavier with the contour and still use the HS stock......
Just an FYI on barrel length and velocity...I'm running a APS built XP-100 w/ 17" barrel that is chambered in 7mm-270WSM. 162gr A-Max's are going 2825fps w/ 63.5gr H4831SC.
