My 308, as of yesterday, has 200 rounds through. I was testing some loads yesterday and was having some sticky bolt situations. Even seeing ejector marks on case haed. The powder was IMR4064 with 210m primers in Rem. cases. One batch was loaded with 178 gr. A-Max loaded from 39.5 grs. of powder to 41.3 grs. 41.3 grs. is max according to Hornady's book. Bullets were set 2.200 OAL by the ogive.
Second batch had the same loads as above but had 175 gr. SMK. Didn't have as much of a sticky bolt as with the A-Max's. These bullets were set 2.227 inches by the ogive.
Even the factory rounds I was using for fouling shots were some what sticky.
When I tried Varget (41.4gr.- 43.2 gr.) and Reloader 15 ( 39.6 -41.4 grs.) last fall, I didn't noticed the sticky bolt. That time I was loading for the 178 A-Max with the same measurement as above.
I am going to try Varget with the 175 SMK when I get a chance.
The gun is a Rem 700P with a 26 inch tube.
What is going on? Should I be concerned?
