[QUOTE="B23, post: 454199, member: 13222"] Because my Remmy LTR already has the big barrel channel I was actually thinking about using one of Bettin's or ABS carbon wrapped barrels. Not sure how much stock you all put in Quickload but after running the numbers, per Quickload, there is only about 50fps difference between the .223ai and .223 I used multiple bullet weights in the mid 50's range and used powders that kept load density right around 100% give or take and kept the pressures the same for both. I compared 24 vs 26 barrels with both too. I used theSAAMI .223 and .223Ackley Imp. from their list. Quickload also showed another .223 Rem but the working pressure for that one was over 62,000 psi so I didn't use that one. Not sure why it showed so much higher PSI and the case capacity was the same as the SAAMI .223 [/QUOTE]
