Probably a dumb question but......

So 2a life in 'merica is kinda sucking right now and I shot my last bit of ammo at a match this past weekend. I shoot a 6.5 CM, handloading Hornady 140gn ELDM. I've had projectiles on order since November.... we all know the drill here.

Anyway.... a long while back in my days of ignorance I accidently bought 500 rounds of the old Hornady 140gn match bullets (pre-red plastic tip). They've been collecting dust because I've wanted to stick with what I know works. I'm at the 2,300 or so round mark down the pipe, so a new barrel is happening sooner rather than later, point being, I would rather not do load development this late in the barrels life.

So my question is this, can I use the same recipe that I used for the Hornady 140gn ELD's with the older Hornady 140gn Match BTHP's and simply adjust the BC? Or is this extremely wishful thinking?

It will be close enough to start with.

I would use the same powder charge. Those Hornady 140 gr. HPBT Match bullets shoot quite well through my Impact action Hawk Hill barrelled rifle.

As long as the charge isn't pushing the upper limit, I would just load them and see. Odds are they will do 1 moa or better as the 6.5 CM is pretty forgiving.
BTW, you might want to order that barrel now. They tend to be about a 5-6 month wait once you order them.
Good luck!

I switched to the 140 BTHP when ELD’s became hard to find. Same powder charge, brass and primer. Just check seating as the ogive is different.
