Coated Bullet Profile - Does it Matter?

[cjmill87]

I'm looking to start reloading coated bullets, specifically Blue Bullets, and wondering if profile (Round Nose vs. Truncated Cone) matters?  I'll be loading in a Gen4 Glock 17 and looking to load something in 124/5 grain weight.

When in doubt go round nose.

You may find TC to be more accurate.But may not feed as well.

With the Blues, I found I could load the truncated nose longer than I could the round nose. This was in my CZ barrels. Didn't see any appreciable difference in accuracy between the 2 profiles.

In my Tanfoglio the TC is more accurate. 

In my M&Ps the RN is more accurate. 

My CZs & Glocks don't seem to care.

They sell small sample packs so you can get a variety of profile/size/weight combinations and work them up to see which you & your gun likes best.

If your Gen IV is throated like previous gens, you should be able to load any of them to your desired OACL. That must be confirmed by plunk and spin.

 

For those who want a longer load, but have a pistol with a shorter chamber in the barrel, here's a bullet style that will allow you to do that. The bullet above the shoulder is smaller diameter that won't touch the lands. Just set the shoulder a bit above the case-mouth as you would with a SWC in .45 ACP.

Thanks for all of the info, I went ahead and picked up sample packs of each to play with.

The bullet profile K-Texas linked is what I use on my Tanfo, Glocks (Gen 3,4,5), and Walther.  Works great & accurate.  I get mine from Brazos.

I can usually load the TC types longer than RN , and they make cleaner holes in paper. Accuracy seems about the same to me,but I’ve never really done any controlled experimenting on that fact.  Both are more accurate that I am offhand.
