Had a Savage 110 in .270.Was at the range with a bud.Everything was going fine let my bud shoot one .Seemed extra loud, Then he got the strangest look you have ever seen.

Ask me WTF.Said it kicked some kind of terrible.Looked through the spoting scope and it hit about 8" high.Went to bolt another round and did not happen.Had to take a nylon hammer and beat the bolt up and open,Then had to use a steel rod to beat the brass out of the chamber.Primer was glued to the bolt face .Took out the extractor and ejector.Savage sent me new parts (springs ,detents and the like ).When I got it back together it woud not cycle hand loads anymore but worked fine with factory stuff.Evidently some how I got to much powder in just that one round .Could not have been a double charge case would not hold that much so I WOULD have noticed.Don't know if it was 1 grain or 10? Lucky nobody got hurt.I always hand weigh each of my bolt rifle rounds.Still to this day don't know how or what I did.This could have just as easily been a REAL horror story.
Spaniel,Not bragging but threw this out for everybody as a warning for new AND experienced loaders.PLEASE BE VERY CAREFUll!!
Just goes to show anything can happen at any given time.I just hope maybe this will possibly help or save somebody down the road sometime..............Alton
