200 fps won’t make enough difference with either of those bullets as far as energy goes at the speeds you will be shooting. About 200 pounds at the muzzle or 150 pounds at 100 yards. Where as hitting where you point makes all the difference in the world.jtaylor996 wrote: ↑Sat Nov 14, 2020 5:19 pmFor the barnes I think I could probably pick something and just go with it (defense loads should be fine at 2MOA). I did notice that my start load on the ladder was putting 3 of the sighters in a touching group... but I sure would like the extra 180fps for defense purposes.dellet wrote: ↑Sat Nov 14, 2020 4:27 pm You should match the data to a target to give it some meaning.
You have a couple loads that look like with a little work could do well in the chrono/data competitions, but they may not be the best for group size or points on target.
Then they all would need to be repeated a couple times.
For more accuracy on the TNT, I'd like to figure out if there were any nodes there, then load 5-10 at each node found and see what groups best.
I did that for my Grendel rifle, and it seems to have worked out (velocity node seems to have equaled small group). I found 2 nodes, one grouped better (.7moa ish). My next thing is to play with COL and see if I can get that a little tighter as well.
If I had to guess maybe there's a node of 19.5gn Lil Gun on the TNT, or do you think that might just be noise? Maybe I could run another ladder between 19.2 and 19.8 at .2 increments, and do 5 of each to shoot groups at the same time.
Then all your statistics are meaningless other than velocity.pj-schmidt wrote: ↑Sun Nov 15, 2020 11:02 am My home defense load with Barnes 110 & lil'gun is 20gr. I bias towards power for this load with adequate accuracy. If I can make a head shot at 7yd and chest shot at 50yd, I'm happy.
My plinking/training load for for 125TNT & H110 is 18gr. This gives adequate performance for those tasks while being a backup option for my primary defensive loads.
Either case I only need usable accuracy (2moa'ish). If I want to make small groups or shoot long distances, then I break out my 6.5 Creedmoor.
I'm not the OP.20X11 wrote: ↑Sun Nov 15, 2020 12:22 pmThen all your statistics are meaningless other than velocity.pj-schmidt wrote: ↑Sun Nov 15, 2020 11:02 am My home defense load with Barnes 110 & lil'gun is 20gr.
