MD,
I’m surprised to know you hadn’t heard of the Cavity Back Bullets! I’m also very glad to know you will be putting them to the test. I too prefer a plastic tip in my mono bullets (I use the 129gr. LRX in a 270Win and a 270 Wthby.). This little 243 will be used primarily as an antelope/deer rifle out to 300 maybe 350yds and my original plan was to use the Nosler 90gr. Accubond. I would love your opinion on that bullet as well!
Can’t wait to see your results and read the review!
