Winchester model 70 243

[Flyeralan]

Many years of hunting with a model 70 in 243. First whitetail and then PA groundhogs. Always had great success with IMR 4350 with everything from 60 to 100 grain projectiles, did bed the action and float the barrel but other than that it was stock. The single thing that made the most advance in accuracy for me was the OAL. That thing shot great with 10-15 thou jump and anything else opened up the groups big time. Sadly, the throat is gone in that model 70 and it sits in my safe and I'm not sure what will happen to it.

I just neck sized and set the next batch at 10 thou off. We’ll see how this goes. I only have a lee neck sizer in this cal and I’m not sure if I’m a fan or not. Neck tension doesn’t seem tight enough.

As always, if you are not real experienced with loading the bullets close to the lands, please be aware that being against or into the lands can cause pressure spikes. Also, make sure you have enough bullet inside the case, especially if you are already questioning your neck tension. Loading only one in the chamber will help avoid setback. Let me know how this works for you.
