Haven't seen the actual number from Hornady but second hand info was 1.640. Seems close as the 180 ELD is 1.538 I believe.I can't seem to find the length of the 190gr A tip..
Can one of you who has some measure one for me and post the measurement..
It's so I can enter the figures into my ballistic calculator.
Thanks NID
Yes...that is what keeps me interested. However they must shoot as well as a 184 vertically to be competitive. If the vertical is twice a 184 the points ‘leaked out the corners’ may be more of a disadvantage. Time will tell.My bal cal tells me that the 190gr A tip would shoot inside the 184gr hybrids by around 8 inches at 1000yds in a 10mph full value wind..
That's quite a saving

Depends on the neck length of the case used. I plan on testing them in a 7 Sherman Short mag; it has a bit longer neck than the parent RSAUM case or .284 Win. I spec’ed a reamer for .245” to run Berger 190’s but hope it keeps the A-tip bearing surface within the neck.What length freebore would the 190gr A tips need to be..??
0.280 ish..?
I checked the CBTO to lands in a .284 (straight) in a barrel with 420rd count. Original FB of .225" and has pushed out about 0.006" since new. At touch the bearing surface/boat tail junction was about .025" past the base of the neck. Based on this and the neck length on a .284 Win I would need .275"+ FB to have room for off the lands seating depth but still keep the bearing surface completely in the neck. I spec'ed my 7 Sherman Short reamer for .250" freebore; considering the long neck on this cartridge it should provide plenty of freebore for the 190's of any make.What length freebore would the 190gr A tips need to be..??

Hi Dave.Long bullet.
So are you saying you need way more freebore than you have then..?The seating die had to be cranked down for the A-TIP’s even below their own ELDM which already requires a lower adjustment than even the 195 Berger.
Not if you are using a Wilson arbor press die. I cannot answer concerning other brands or types.Hi Dave.
Did you need a different seating stem for the very pointy 190gr A tips..??
