My Tikka T3X hates a clean barrel and takes a dozen or so rounds before it starts shooting amazing again. I hate cleaning it but keep a cheap box of round handy to foul the barrel before shooting my reloads. I thought I was the only one.
I use 140 ELD-M’s out of my 6.5CM with great success on antelope and deer out to 700 yards. That being said they have been broadside shots and exploded inside the animals. My last antelope at 660 yards the bullet did not leave the back side.
I have a 7mm Remington Magnum I load with Barnes 150...
Little late to the thread but I load up 10 rounds in increments of .4 grains. My lowest charge is middle of the road book data. My highest few will be over book max. I’ll start looking for pressure signs as I get close.
Here is a pic of my last one for my 7 REM Mag with my Tikka T3x. As you...
