I use powerbelts in all three of my end loaders! 2 of which are traditions, 1 an e bolt with a 22" 1:32 twist barrel I use the 245g arrow tip and 100-120g powder 777 works nice. I also have a traditions lightning bolt with a 26" 1:32 twist barrel that gun likes the 295g bullet and 130g of 777. experiment thats the only way to tell for sure end loaders are all diffrent but the powerbelt bullet is about as consistent as they come they shoot well in all my guns. happy hunting
