[Which Low Cost Bullet for Glock 17?]

17 hours ago, Brewski said:

Keep in mind that Blue bullets are .355 as the default size, although you can special order other sizes. Most others - such as BBI and ACME - are .356. 

 

I wonder why they size them at .355 when just about every other plated or coated bullets are at least .356?  I would think it may cause some leading issues.

Here is some data I collected this past winter. I normally fire 10 shot groups, so I don't why these are only 5 shots.
