I have a Contender Carbine in 30-30 with 21" barrel and need loading data to this bullets:
Hornady V-max 110 gr
Hornady Interlock 150 gr Boat Spire Point
Hornady 150 gr FMJ Boat tail

Or is it someone who know in which velocity they will work best?

If your going to reload I suggest you get a Hornady reloading manual before you blow your hand off ,or worse ! What is the twist in your barrel ? 150/Gr will probably shoot good 110Gr is for a 1in14 twist .

I would agree, get the Hornady manual. Better yet, get that manual and a couple more to compare.

If you don't want to invest in a manual, you can get load data at the Hodgdon powder web site which if I remember correctly is at:

www.hodgdon.com

Contender factory barrels usually are 1-10" twist for .30-30. There is lots of published data for the caliber and most powder makers have free guides and the starting data for the 150 grain loads should work for the ones of the same weight. The lightest bullet I use in mine is the 125 gr. Remington PSP. My chrony show loads getting it the 2400fps range as I recall and 2200 for the 150 grain loads.
