Brass inserts versus tubes..

[twitchstick]

Ihave had better luck using inserts and adapters for adding weight. I shoot 250 to 260 up front.

I have also had much better luck with brass inserts than tubes. The inserts stay put, the tubes never did.

I use 50 grain brass inserts on my GT 55/75 with 200gr muzzy phantoms and the penetration is fantastic. I also like the brass inserts since they are much stronger than the aluminum inserts and are tough to break.

Been using both 8gpi tubes with 50 or a 100grn brass inserts on both 350 carbon express and Gold tip 75-95. 28" arrows run between 650 and 750 grains. These hit with athority and keep that weight up for heavier bows.

I shoot GT 55/75 with 100gr brass inserts and 150gr points/broadheads. My arrows are cut at 30.5" and this tunes out real nice for my 50# longbow and my 50# recurve (both Sarrels bows). The 250gr up front put my FOC at 22.7% according to Stu's calculator. I am very happy with this setup and have taken lots of animals with it.

I prefer brass inserts hands down, over tubes.
