75gr .223 pet loads?

[maroonandwhite]

I am wanting to load up some 75gr boat tails and am wondering if any of you have some load data on a starting point. I don't have my backyard range setup yet so range trips are valuable. I have shot the minimum 21 grains and they are as expected pretty weak. I have loaded a few at 21.5 but haven't shot them yet. I guess I can load a few at each .5 interval but I'd like to load a good number of rounds and if I could get a good idea at what may work best I will load more of those.

 

I have also have some 55gr VMAX that I can load if you have any ideas on those. I want to get rid of them as they are a pain to seat.

 

I'll be using H335. I also have a pound of CFE223 I can use.

I'm not much help, but I really like 25.5 grains of cfe 223 with my 60 gr vmax.

I have a load for the 77 and 80 using TAC.  The 77 load matches the MK 262 that the military uses.  Unfortunately the info is not with me here.  I should be able to dig it up Monday.

Worked up a load for my sig 5.56 using 75gr bthp and 25gr of blc-2. It runs really well in that gun. One if these days I will remember to try it in one of my AR's.

That is really close to max so I would edge up to it. For some reason the sig really likes hot rounds. Don't know if it has to do with the gas system or what but it really likes hot and heavy (no comments from the pervs please)
