[QUOTE="Capt RB, post: 2803453, member: 85987"] Rebated 115Dtacs run fine in an 8tw. The original DTACS need a 7.5tw for me at sea level. I only shoot in the winter in colder temps my club range is 34' above sea level. In my 243AI I've run 107smk's to 3280 with Rl25. H1000 is easy to keep that class of bullet at 3150 for PRS It will push the Dtacs that fast but with more pressure. 26 or 27" barrel can't remember what it was. Now it's wearing a 18"308 for a truck gun [/QUOTE]
