But again, if speed isn't the absolute end all, 2400, will stop the sooting, and give slower speeds, than you are used to, with bullets in the 230-325 realm. Even with those slower speeds, there is enough residual Umph, to get any job done and accuracy is off the rector-scale. Wanna see 1/4 MOA @200yds? Use Hoots suggestions on crimping and use either 250gr FTX's or better yet use the 200gr Barnes XPB's (http://barnesbullets.myshopify.com/prod ... fb-460-s-w) or better still, use the Barnes 275gr (http://barnesbullets.myshopify.com/prod ... fb-460-s-w) with 1680. I was rewarded with sub 1/4 moa @200yds. with these and I think one should really try 2400 with them as well. Speed won't be so great, but world record groups might be in the offing and you'll still easily kill everything out there.
Fyi, though I like my crimp the best (The LeGendre-Side-Crimp), over-all, for getting the powder to cook well, before the bullet leaves the case, Hoot has better suggestions for Barn-Stormer Accuracy Crimps, for when a warm-fuzzy is better than a Group Hug..

I know it can handle what ever load is in it. My twist rate is 1/16 and had zero issues with heat or the brass, looks no different than the hornady. I don't shoot one after another like some with ARs do, its a bolt and heating up due to higher velocity + 1/16 has not been a issue so far.
No Im not going to try to hit that load on the first shot. I know its been done in a factory load.
I won't be in uncharted territory because I already have the ammo that does it and works fine with my gun.
The unknown is the powder they used. I suppose I could pull one of the bullets and weigh the powder, take a photo of it and even flash test it for burn rate.
So the goal is just to come close to matching already readily available factory ammo that has a 240gr .26 BC at 2400 to 2500 fps.
1. Early goal is just to get acquainted with the round and load cheaper 240gr interlocks at low loads.
2. Final goal is to match the ammo I already have and shoot with a 240gr higher BC copper bullet.
This is well under what someone else on this forum did with s 2800+ fps and 4000 ft pounds. I think he said he ran out of room to put more powder in and still did not have issues with the gun. I don't intend to go that far, but a little more than AR loads.

I think that was Wildcatter that pushed the 230 FMJ to 2800fps in his lab.
In other words, Timothy LeGendre in his ballistics lab. AKA, The father of the 450 Bushmaster.
No way would I push that speed. LOL.
I did my 2700+FPS quite by accident. It was spooky.
