I've shot more Montana Gold Bullets than I can count and have never had a problem with them. A friend of mine will buy their 'seconds' and load those and they shoot great too.
Many of our local sporting goods stores sell the MGB and can't keep them on the shelf in any caliber. For an inexpensive bullet I don't think you'll have a problem with them. And I don't say that because I live right down the road from their production location either!!
