Well, I bought the 18" barrel upper from Tim, so I'm not sure if the 130s will get the velocity and trajectory I want for hunting. The 110 TSX will be quite sufficient, though, when I handload them.Southern Devil Dog said:I load 130 gr bullets, that is all i can get my hands on right now . They do have a great nock down power compaired to the 110 and 115. I belive it might be in the length of the bullet. Plus i do have a 24" barrel.
so the Speer Hot-Cors in 130gr. will get me the same trajectory as the 110 Pro-Hunters? I can handle that. If I'm putting the right info into the JBM calculator (Speer 130gr Spitzer SP @ 2500 and Sierra 110 SPT at 2600 ), then there is only a .5" difference at 350yds (sight height for ARs is 2.6", correct?). However, I like the idea of having an extra 230ft-lbs of energy at that range.Tim_W said:With an 18" you can get them to 2500. If you look at the Speer 130 SP they have BC over .4 and they are 1.03 and 1.08 With that BC they will have the same trajectory as the 110 Pro Hunter out to 300+ but with more energy. 130s are really at the very top end of what can be used in the 6.8 ans there are only a few that are practical. The issue I think with SSA loading them is the powder they use now may not have the right burn rate for the heavier bullet. But it may. In all honesty there is nothing that a 130 can take at what we can drive them at, even up to 2600 fps, that a 110 Barnes TSX won't drop. I like the 130s and that is all some people can get without special order. If you want to try loading them I suggest IMR3031, H335, Hodgdon BL-C2, Accurate No.2520, Rel 10x One of those should give you a good load at 2500+ Again this only applies to the shorter 130s. You need to stay below 1.1 in OAL of bullet otherwise there is not enough powder room.
I'd like to know this too. I've given some thought to loading some of these and Lee dies are what I use too.eta: I just noticed that my Lee 6.8 dies aren't supposed to be used with Speer bullets. Has anyone had a problem loading Speer Hot-Cors with the Lee dies?
