Lighter bullets for 300 to 500 yards in a 6BR

I help run the varmint matches at Lawrence Co. sportsmen club and also shoot the Mcdonald sportsmen varmint matches and I have doing this for the last 20 or so years. Myself and a few other shooters have tried the lighter bullets (80 and 90 gr. bullets) for the shorter ranges. As far as I know everyone went back to the 103 to 108 gr. bullets, but the lighter bullets were shot in 6br, 6 dasher, ect. 8 twist or faster barrels and the heavy bullets shot better at all ranges. There was on fellow that had a 10 twist 6br and shot the 90gr. Scenar and did very well out to 500 yards I tried the 90 gr. Senars in a couple of 6br's. with 8 twist barrels but they didn't shoot as well as his.

@drags Thank for the response.

"As far as I know everyone went back to the 103 to 108 gr. bullets"

Is that for larger than 6BR cartridges?

"and the heavy bullets shot better at all ranges."

Does that apply to 6BR?

Thanks!

Steve I was referring to 6br, 6dasher type cartridges but there are a few fellows that shoot 6x47 Lapua's. I think the general consensus is the heavy bullets do better in all conditions. My post is referring to our shoots it may be different in other places. Another opinion at our shoots for the 1to300 yard shoot in very good conditions the 6ppc is very good, for the shoots out to 500 yards the heavy bullets are the most popular in all conditions for the br and dasher type cartridges.

Walt you’ve forgotten more than I’ll ever know. So I’ll ask you.
What does wind bucking mean and what is the science behind it?

It's slang for resistance to deflection in the wind. The physics are complicated, but essentially, higher weight, higher velocity, and lower drag shapes cause the bullet to be less impacted by wind. Higher weight bullets tend to have lower drag shapes that make up for the fact that you cant' shoot them as fast.

This weekend I'll be shooting my first ever "medium range" match (500 yards), I'll be shooting 90 gn Berger targets over Varget. I know I'm not a true test for the lighter bullets but I'll post results just for giggles. I do have the 95 gn VLDs that I may work on too.

The base to ogive is much shorter on those vlds. Won't make rifling on a .104

Mike @gunsandgunsmithing saw my post and let me know that the FB is .098 so I'm good to go!

If you are referring to the 95 vld, you are only .006 shorter than a .104. My bet is you will still be .040 to .050 short of jam on the 95vld. Berger list the base to ogive dims online. The 90 is almost spot on the 105 hybrid, not the 95 vlds case. The 90 has a shortened boat tail adding bearing surface
