Barrel set back.

[WIB3]

Does setting your barrel back 2” change your original load and bullet seating measurement.

It can, but typically just some fine tuning is all I needed to do.

It may some, but a few groups will tell you if you need too tweak the load some.

The slightly shorter barrel may require a bullet seating depth/jam tweaking...If the same reamer is used you can start right on your old settings from when the barrel was new. I had one 243Win shoot better than original. My first 6mmbrx does ok & now it is just for fire forming..The BRX had a really hard life. grin mike in ct
