the barrel on my blr in 308 likes to get pretty warm after it shoots

which means to be accurate 3-5 minutes between shoots is a must. i developed a load for it that will group at about .8" but i just can't sight it in because of inconsistencies in the barrel temperature

but if i shoot the gun, leave it for 30 minutes then come back and shoot it again, then do the same thing once more it'll shoot a near perfect group...

any suggestions... what should i do
