So far I have tried Sierra 75 HP's, Swift Scirocco 100's, Barnes TTSX 100's, Nosler 110 Accubonds., Berger 115 VLD's, Hornady Interlock 120's, and factory. I'm really concentrating right now on the Swift, Accubonds and Barnes mainly for the up coming Antelope hunt. The Bergers I won't use on Elk, but it's fun to see what they will do accuracy wise, it's just not a big priority right now. The 75's shot great , the Bergers I wasn't too impressed, BUT I haven't played with them enough to say yea or nay. So far the Barnes, Accubonds and Swift have all shot pretty good to really good.
I have tried a lot of powders from IMR-4350, RL22, RL25, H-4831, IMR 7828 long cut, and Ramshot Mag. I just got in some Ramshot Hunter to play with down the road not sure if it's really slow enough to get the velocities I'm looking for, might be OK for the 75's. So far the 7828 has given the highest handload velocities and pretty good groups. The biggest problem I'm having is copper fouling with the Sciroccos & Barnes pure copper bullets, and the unavailable load data for Ramshot mag powder. I do have some data , but I need to get it from the horses mouth. I'm running by the guess method and no where near max from looking at the cases. I have an E-mail in to Ram Shot for load data. H-4831 gave me the best accuracy just not the best velocity with all 3 bullets. I have about 50 rounds to test when the rain stops including a few Bergers. We will see hopefully next week in between monsoons if I can get to the pit without getting stuck. I kind of went with a wide varity of bullet weights to see if this rifle likes one weight over another. I could amost flip a coin between the TTSX, Sciroccos and Accubonds, one reason I'm spending so much time on the Scirocco is a slightly higher BC's and a little more velocity, the down side is they copper foul way more. I need to run about 3 more test on these 3 to get where I'm happy.
