243AI load info please

[TEAMSENDIT]

I currently have an FN SPR action at my smith and he is building me a 243ai 3 groove 8 twist 28" barrel to shoot the 105 class bullets. I am looking for peoples pet loads with velocities. I have not picked a specific bullet that I want I just know I want at least 100gr and yes I know to start with standard 243 info and work up from their.

I could also use some fireforming loads if you desire because I have 400 lapua cases that need to be formed.

thanks for your time and info I appreciate it

in my sps varmint .243 ai i fireform with 45gr of h4350 in hornady brass with a 70gr smk. works well for me. as for pet loads i can only help with lighter varmint loads as that's all i use this gun for. hope that helps.

Re: 243AI load info please

fire formed mine with the same bullets that I was going to use
ie 107 smk's and 105 amax's and developed drop charts for both based on those 2. One of the best groups I shot was when fire forming so that made it nice however with the ai version I now have a drop chart for fire form loads and AI ...
rl 22 is what this tube likes I would try it

I would but my loads are "warm" so start with 45 to fire form or lower and do your
version of a "ladder" test and see what you get
fed 210m primers and
I'm using a type s bushing die

good luck
