when was the smk 168 boat tail changed ?

[6bra1k]

ok the original 168 was a 300 meter competition bullet with a SHORT RANGE boat tail.
some where in its life the boat tail was changed to a long range boat tail.
my guess is some time around the introduction of the 175 mk.
sierra is closed, so i cannot ask the source.
thanks

They have the new 169 for long range with longer boat tail and closed nose. Stays stable at 1000 yards.

The 168 MK boattail has not changed since its inception to my knowledge.

The 180 SMK boattail was changed back in the late eighty's I think it was. Shooters were not real happy with the change. The 168 has not changed to the best of my knowledge.

@6bra1k any chance you mean the other 169 version (SKU2268C) rather than the old 168 SMK (SKU 2200C)?

They made a 168 match king # 2200 then introduced a 155 match king # 2156 which was for longer range per Sierra. The 168 has a dedicated machine just for that bullet only per Sierra.

As I understand it, the boat tail 168 called the "International HP" was the precursor to the current 168 SMK, both share the 2200 part number. It was the original 2200 bullet, the "International HP", that was designed for 300M shooting.

Here is a visual comparison and a few more nuggets of information:

i think the 2 look diff in oal...and who knows on the boat tail.... just looking for a date. and to the others..THIS is what i am talking about.

Other than normal manufacturing tolerances the only differences in the original offering and what is made today is the dropping of the name International. The original boattail length and angle has not changed on the #2200 part number bullet.

I don't know for the 168, but the 175 came out in 1995.
