Hello,

I'm putting together a 300 win mag and have a Krieger Heavy Varmint barrel with a 5" breech. What is the difference or the benefit of a 2" vs a 5" breech? I want to cut this down to 26" and will be my 1500-1800 yd gun. The shortest distance I'll shoot it will be 800yds or so since I have a Scar 17 and LRP for 1200 yds and under. Does the breech length matter for any of this? I can always save this barrel for a .308 build and get one with a 2" breech.

Thanks.
