Hey Guys,
A general question.... Is there concern or special precautions loading plated bullets for G20? Issues leading the polygonal barrel?


Just recently started running Xtreme 180s HPCB  ( heavy plated concave base ) in a stock G20.  After 200 rounds there was no problems at all, seemed like shooting a fmj.  Good price and accurate, oal lenght of bullet shorter than remington fmj.

Yes ,
 There is data for the RIA 5" gun and some data for a Kimber 5" . As a general rule the difference  between 5 and 6" barrel is 40-55 fps.

I'm taking it you don't have a standard 5" barrel gun here. Bummer, I want to know the difference between my 5" 1911 and my 6" long slide 1911.

Has anybody tried using 40cal/10mm 180gr RNFP pulled bullets.These bullets have been commercially pulled by an ammunition dismantler to reload?

Pulled bullets I've used work just fine... you'll usu find a pull mark/ring near the top of the bullet, those I've seen had slight mark but its a non-problem.

I have also used the Pulled bullets from Rocky Mountain Reloading.  They get some good quality premium bullets at times.

In my opinion, most of these figures come from ballistic calculations and not actual firing a gun or bullets from a gun.
Make believe pressure calculations,barf, MUZZLE BLaST-VELOCITY FROM MUZZLE  no way- MARCH 17,2016.

slicelee please understand, 475/480 made the original postings here and were tested from the Guns: Caspian 6" Custom , STI Perfect 10 , G20SF w/extra LWD 5.47" barrel.  So his velocities are as good as his Chronograph readings...

He also has the Quickloads Program and has taken the time to run the info across the QL program to add the estimated pressure values in another post.  The values for small cartridges can be slightly off, but short of having a true pressure barrel to test with it, the values are there for study purposes.

As The Shadow has stated ALL of the velocities on my posts were fired thru my guns.

How does their price stand compared to my Precision Bullets 185 grain coated RNF's I get for $90 shipped per 1000?
Some people think I'm paranoid because I have so many guns. With all my guns, what do I have to be paranoid about?

prices aren't my reason for buying from them, but the reason is you can get pulled heads that are hard to find like Gold Dots, Hydra shok, etc

Does anyone know which powders Doubletap Ammo uses to achieve their velocity

Thanks. I left the most important info out of my question. I use the 135gr for carry and the 200gr hardcast will be used for hunting this year.

Gents,
Thanks for your replies about loading plated bullets. The article in Blue press a couple issues back was also useful. I have been crimping way too much which resulted in the most inaccurate loads I have ever produced. I had completely given up on plated but maybe it's worth another look.
