7mm TCU barrels
« on: April 05, 2008, 07:23:01 PM »
  I see the guys here are talking a lot about the 7mm TCU.  My Question there is about powder types.  Have been using slow burning rifle powders but, it's only a 10" barrel.

With cast bullets (gas checked), what powders are being used nowdays? ???

I use the Blue Dot, AA#2015BR, AA#2230 with good results from short barreled Contenders(10" and 14").
I use Varget and RL-15 for the longer barrel(21") carbine TC.

I'm not sure about cast bullets, but I've had good results with H322 and IMR 4198 with jacketed bullets out of my 10".

 Thank you , Scott
   I appreciate all the help I can get.  I love the calibre but, it's wanting to eat me alive at 200 meters lately.

WW748, H4895, VVN133, and H322 are excellent powders for this gun.
I use 748 and have some N133 loads to try.  RCBS 145 Sil bullet.
