re: 17 bmag
I'd recommend a trip over to rimfire central, they have a dedicated "complain about the b mag" section. Its titled the 17 wsm sub section, but it should probably be renamed " all I hate about the b mag" : )
The B mag let a lot of people down from what we had started to expect from savage. Longer term memories remember sub par quality savage, but they had really stepped it up in recent years. The axis, edge, and now b mag seem a little less than where savage quality had been going the last 10 years. I've noticed that savage customer support is slammed right now, in all fairness it seems that everybody in the firearm industry is either backlogged, out of stock, or putting you on hold.
I'd hazard a guess that your the first one to complain about it being hard to open, most are amazed at what it takes to cock the firing pin on close. That hard on open would lead me to believe an improper headspace causing the brass to swell and stick. How does the brass look when it ejects?
Sorry It was such a let down. I remember when the cryptic announcement was made, even waited up all night for their new year launch last year ( it was delayed till the 13th ). Then the extreme delay in production, my gun slush fund money set aside for the b mag literally had dust on it when they hit the shelves. I got down the lower 48, called every store in OR, WA, and Id to find one in stock, drove 271 miles to look at one. Left the store as my wife describes it "looking like a 5 year old who found out the Easter bunny, Santa, tooth fairy were fake and that my puppy had just died".
But the inner 5 year has a lot of hope, Savage seems more than willing to replace malfunctioning guns. My shot show fingers are crossed that the Winchester and volquartsen 17 wsm's are out and blow my socks off.
