If anyone knows of any HSM 140 Berger ammo in stock please let me know!!!! I'm heading to Nebraska in 3 weeks and only have about a box left and still need to work some drops.

get a pound of H4350, a box of bullets, fed. 210M's, load them to the same velocity, they'll shoot the same

I'm going to also do that but I still don't have much brass either. Was gonna shoot the HSM and then load the brass. And then there's the time to get it done element also...

the method I use for dope charts takes around 20 shots or less to get the dope out to around 750-800 yards. just use a good ballistic program and keep all the data as accurate as possible, a barometer will save a lot of ammo during testing and at sight in in your hunting area.

I have the Nightforce/Exbal program so I'll use that or maybe even the Berger calculator. I thought for sure it wouldn't be a problem finding 6.5x284 ammo so I didn't look till today and now can't find any!!!! lol

I really like exbal, once I get my actual data in its good way out there, don't believe the published BC's to get my charts to match my trajectory I run the BC of 140 bergers from the published .64 to .7 and its dead on to 1100 yards, yours may be a tad lower since the gibbs will run them around 250-300 fps faster than the 65/284
