Re: 375/408 Banded Solids Test

Kelly,
I have built two 375's for my personal use, the first one was to test a McGowan
12 twist barrel. It shot the 350,s great, but the longer bullets were not so stable.

My second rifle has the Gain Twist experiment, i wanted to move into the higher BC
bullets that are coming out, remember the standard twist for the cheytac is 11.5 and
that shoots the Hookers good and they are a high BC of .945 plus the SMKs at .770
I do a lot of R and D here with barrels and twists and new wildcats, some work some dont.
I have tried most twist rates but when you start dealing in the extreme BC bullets your
going to be stuck with one bullet type or make.

Long range ... well the SMK has enough energy to kill an Elk past 2400yds, the 370gn RockyMtn
will have even more and these are legal hunting bullets. So in my opinon if your building a rifle your going to hunt with then get a barrel that will handle these bullets. If you push these bullets to 3200fps and over spin them you will see poor results. It takes quite a while to get a
gain twist barrel from Bartlien. I would like to try a Gain twist in somthing like 20 to 10 exit, Just for the Jacketed bullets.

Re: 375/408 Banded Solids Test

Dave,

I think your focus on projectile adaptability/flexibility, in a hunting rifle, pretty much reflects what I have been able to gather from the hunting community.

I took the cue by moving to the ~6 caliber PDT core projectile. It will be interesting to learn the extent to which increased specific gravity reduces the rpm requirement. I have a suspicion that the ZA375/6.0-W will return to the 11.5" twist specification of the Hooker... but with a considerably higher BC.

Las Vegas will be telling.

Noel,
I am looking forward to trying the 6 and 6.5's in my barrel. The Vegas Shoot should be
very interesting to say the least. It will be amazing to see the amount of data that is
obtained.

Dave

Great pic Dave. I thought the GS bullets were coated with a black moly? Is that an older bullet or was it ordered without moly? Or did it just come that way?

Mark,
They might offer them coated but these are the latest manufacture. I just got them in
a couple weeks ago.
