Snowman i just tried what you said and all i can say is WOW!!!!!.I filled one of my Carbon Tech arrows with silicone and shot it out of my Allegiance and it made my already quiet bow more quiet,but the real test was when i shot it out of my Gamemaster and it made that bow almost dead quiet.. The arrows weighed 352 grains before the test and not sure what they weigh now but Sunday morning i will be at the range and if it shoots as good as it sounds i will be filling all my Beman Classics.
