Sierra 100 gr 6mm Gamechanger

[fmuguira]

Anyone worked with the Sierra Gamechanger in the 100 gr 6mm variety?

What I ve been able to dig up sounds like they re a good game bullet and pretty forgiving regarding accuracy and tuning.

Especially interested if .516 G1 BC holding up? If so it's right with 103 Eldx and gives a guy another option in these times of scarcity. I found some in stock and considering picking up 3-4 boxes for my 6 Creedmoor and 240 Bee.

Thx for any experiences and findings!!

I have shot them in 243 with 10 twist barrel. Heaviest bullet i could use in the 10 twist. Shot good to 1000 yds in my gun, but bc is only .430 not .516 . Its a good hunting bullet for the .243 but for 6 creed with a 8 twist I like heavier bullets with better bc.

What is the twist in your rifle?

I ve got some with 10 twists and some with 8 twist. I have a tough time believing Sierra rates at .516 and it's only .430. Sierra for many years has had the most accurate BC s until Berger /Litz joined the scene. Now most bullet manufacturers have joined the party and quit over-inflating their BCs.

I was thinking maybe his 10 twist diminished the BC?

Sierra website says ..430 above 2800 fps .

 

[fmuguira]

8andbait… that could be. A .430 is more likely the lead tipped GK BC; not the newer GameChanger. My thoughts at least.

This is the 90 gr

This is the regular game king

 

[fmuguira]

Exactly! Thx for looking all three up!

I've used them out of a 6mm Creedmoor with great success on whitetails out to 435 yards.

Tough enough bullet for up close yet still expands well at distance. Much tougher than an ELDX though.

Thx Hickswr. Good info.

Any experience with BC and if it seems to hold true at 600 plus yards??

Sierra lists the G1 of the 90 grain at .490 and applied ballistics has it listed at .411.
The 100gr isn't in the Applied Ballistics library yet
