If you want accuracy, go JHP. I have never found a FMJ-RN that is more accurate than a JHP.
I just got in another order of 3000 PD 124gn JHPs.
If you want total reliability in a semi-auto, most people trust FMJ-RN. I have never seen a difference, except for some old .45 JHPs with huge hollow points.
I would order a case of Montana Gold, but Precision Delta are very good bullets and I shoot them all the time. With PD, you are best off ordering at least 2000 of any one bullet and placing an order for at least 6000 bullets. With MG, you only need to order one case to get a great price.
I see no reason when order quality bullets not to order several thousand. In the worst possible case, there is always a market for jacketed bullets.
