300 WSM 230 Berger load development

Exactly, the trade off to me has never been worth me even trying the 230. But people care about BC because the majority of shooters are using bullets for purposes other than know distance target shooting.

I think i understand what you mean, but i personally feel the lowest form factor for a given caliber is simply the most aerodynamic for that dia.

Unless you want more energy, or a flatter traj. Form factor basically tells you which bullet to use.
 
I went with the 230’s on the recommendation of some phenomenal shooters. I was new to the wsm world and those who I spoke with all shot the 230’s. I have a few boxes of 215’s that I am working through now, as you said Alex, trying to decipher if the extra bullet weight is worth it. I had the wise idea to try and push the 200.20x at 3050. While it’s possible, having a chamber throated for 230’s did not leave much of the bullet left in the neck. A shorter throated neck could really work well for it
 
One look at the form factor will answer that. For the life of me i cant understand why people care so much about BC numbers anymore.

The 155 Hybrid and 200 Hybrid have near identical form factors. Even though the BCs aren't even close, you're saying they will fly the same in the wind?

Their form factors are actually not very close.

155gn ( .953)
200.20x (.920)

The 215 (.915) will actually fly closer to the 200.20x than any other 30 cal in the lineup.
 
I compared the 155 Hybrid to the 200 Hybrid, not the 200.20X. Nearly identical form factors but the BC is about 30% higher on the 200 Hybrid. Every once in a while I get hit on the head with something new that I was overlooking. Checking to see if this another one of those cases?

Ooops sorry about that i mis-read your initial post.

The heavier bullet will always drop a little more, drift a little less, and launch slower but they have very similar drag characteristics. The difference in bc is directly related to the difference in weight, not profile.

This is why the 200.20x is a superior bullet. Exact same weight and lower form factor. The 215 even lower yet. The most efficient drag characteristics of bergers 30’s.

Run the numbers, and be sure and run the wind at both 90 deg and 180. That extra twist for the 200 will come into play.

I am reading one of Bryan Liz's books and he was stating the 230 in a standard 300 WM it comes really close to the 338 Lapau in an ELR sceario. So I was wondering about it in the WSM.
