Most reliable heavy Glock 20 with standard barrel loads for bear?

[Ramjet]

the 100 lbers are the worse young hungry and stupid.

I researched allot of testing in ballistic gel and really like the 180 grain xtp but my 220 grain WFN hard cast run well and go deep.

My suggestion with regards to defensive use is this use a bullet that has good track record and what you shoot very well in high stress drills.
