Can't get under the bar

Squeeze your shoulder blades together and use those big traps as a cushion son!

Beech...good looking out.

Sounds like a shoulder mobility issue.  I get a lot of mileage out of doing dislocates, but YMMV.  There's plenty of good mobility exercises out there, so fire up the internets and get your learn on.

Word.  The discomfort goes away after a few sets, but at the beginning it is awfulsauce.

Dunc, you got an actual 10-15 minute warmup routine in your lifting life?

Have had this for 10 years since they cut my delt, yep, it hurts bad the first couple of sets.  I do shoulder mobility and cuff and all that, still hurts.  Price paid is all I figure.  Play through.  

Seems to me that addressing the issue, as opposed to just switching bars like people are advocating, would be the best course of action.

Something that hasn't been mentioned that happened to me.  I had the same type of thing happen to me over the years.  Started with the knee issues that turned out to be advanced arthritis and the destruction of the cartilage in my knees.  I can squat almost to hamstrings to parallel but any lower, I get bone on bone and the knees swell.  So I really didn't do much squatting from about 2002 and later.  I decided to try some squatting a few years ago and noticed that I had no shoulder flexibility and it was very painful to hold the bar in a back squat.  I simply chalked it up to mobility issues.  Well long story short, found out my shoulders have about as much arthritis as my knees.  Just about all out of cartilage on the rear portion of both shoulders.  This is why I began noticing an increasing lack of range of motion when I threw the hammers and any lifting overhead and back squatting.  You may also want to find a good ortho and have that checked out too.  The pain from the shoulder arthritis is horrible.  I can live with the knees but the shoulders have been much harder to deal with in the last 3 years.  At least go check it and rule it out.  I never really even thought much about developing shoulder arthritis until it was too late to change things.  Just my experience with similar symptoms.  

Paul beat me to it.  A powerlifter friend recommended middle finger on the farthest rings and thumbless grip.  Pushing up into the bar is noob stuff.  You don't need it if you squeeze your shoulder blade together and create a proper shelf for the bar.  I'd try a lower bar position.  I use the same low bar position for both oly and power style squats.  Granted I don't squat anywhere near your maxes so take this with a grain of salt.

Been doing a lot of stretching and stuff trying to get looser before I start.  Thanks so much for the input y'all!

Wing span is a factor

I can do OH squats.  I've got squats on the list today so we'll see.
