Sticky Bolt

[bsekf]

I have a Savage 110 Single Shot action that I have taken the ejector spring out of. I have a 6BR barrel on it. I am shooting 95 Gr Nosler BT over 30 gr Varget/CCI 400 primer. (very accurate) Cases are trimmed to correct length and I am jumping the bullets. The bolt opens easily but needs a bump to move backwards. I have reduced the load to 29 grains and it does the same thing. The rounds load easily, no cramming when I close the bolt. Fired cases do not show high pressure, slight cratering but no blown primers. I have some with a lighter bullet and a max book load of Varget and they work fine. Any ideas?

6BR

CCI 400 , these flow to easy.

slight cratering but no blown primers

Change primer. The CCI 400 is only good to 40,000 PSI. imo.

. I have reduced the load to 29 grains and it does the same thing.

Different bullet, different pressure. Try 28.5 grs. Still there. Not the load, my guess.

Both my Savages Axis rifles in 223 & 6.5 CM do it. Normal for me.

Hitting the extractor cam does that. "Extractor cam" may not be the correct term.

My sierra manual shows your load is 1.5 gr over max for a 100 gr bullet but within safe load for an 85 gr bullet. Does the problem go away with a lighter load?
