Re: I think I maxed out the velocity on my 26" barrel
It is a Hall E Action, glued into a McMillan McHale stock, Kelby rings/bases, Nightforce 12-42, Jewell trigger, Douglas 26" barrel (#3 taper I think). All of this was smithed by James Messer.
Best load is 93gr of RL25 and .030" off the lands. It will go into one hole depending on the shooter. RL25 seemed to be the only powder (RL25, IMR7828, RL22) that was predictably accurate from group to group in the 3400 FPS velocity range.
My brass is the necked down .338 Lapua brass. I use Neil Jones bullet seaters and the Redding FL dies for neck bumping and a body dies I made from another Redding full length sizer for the cartrige base die.
I actually shot them into a .060" group and had to pull the target to verify that I had indeed not missed with the group shots. At 42 power, it looked like one bullet hole...... The reason was that it was one bullet hole. It actually did this with 94 grains as well, but the bolt is sticky when the temps climb up above 90 degrees.
Even a poor shot like myself can have periods of glory with good equipemnt.
