GS Moly Coated Bullets

I've been checking out these GS bullets and some look very interesing.

GS Custom Bullets - Made in South Africa - Proven on the toughest game on the planet.

The .308 cal 177 gr HV bullet has a BC of .638 and ave BC of about .620 out to 1K which is a better BC than any other bullets of that size and weight that I know of. And this is a "hunting" bullet. Another interesting feature is that they open and expand down to 1600 fps. Also, they are moly coated which the manufacturer claims increases velocity and barrel life. Their moly is different than the spray on type and other types used by other manufacturers.

So, looking at where the rubber meets the road, I'll compare this bullet to a 180 E-Tip with a BC of .523 and an MV of 3000 coming out of a 300 WM or WSM, and using a theorhetical MV of 3100 fps for the GS HV bullet. I'll use 3000 ft elevation ( a conservative western elevaion). My personal definiton of effective long rang hunting performance is the distance a bullet will travel and expand on game.

The E-tip's effective long range hunting distance is 800 yds based on a minimum opening speed of 1800 fps.

The GS HV's effective long range hunting distance is 1200 yds based on a minimum opening speed of 1600 fps.

Also, the GS bullet drifts 31" to the E-Tip's 41" @ 800 yds in a 10 mph crosswind.

Edited: corrected the MV's to 3000 and 3100.

This is quite a significant difference.

Any comments?

Anyone have any experience with these bullets?

Re: GS Moly Coated Bullets

Hello,

I have tried several versions of them in .30 caliber..... I still have some if anyone wants them. They were extremely accurate (.375" six shot groups (two shots per day for three days at the same target) at 400 yards), but they did not meet the trajectories associated with the advertised BC. So I quit shooting them.

When you say "if anyone wants them" does that mean they're free?

+1 I'll play with a few.
What BC did you come up with. They claim their 197 is in the .9's

Re: GS Moly Coated Bullets

someone on here tested the BC of a bunch of 308 bullets maybe a year or so ago. the BC of the GS Customs was WAY lower than what was advertised. like .2 lower if i remember right.
