This is only related to bullets used by 'other' companies.
I got 1 or 2 (?) boxes of Winchester 6.5 X 55 with 140 gr 'soft point' with the purchase of a Win 70 FTWT.
I killed a few deer with them and they worked -- I graphed them @ 2750 fps.
I shot a few into my pond dam and recovered them. They expanded back to the "Interlock". You could see it plainly.
I took pix and posted them @ 2012 or so. UNFORTUNATELY those pix are on PhotoPUKEIT and I can't upload them to
any site today.
Those factory Win 140 were Hornady Ils.
