220 freebore is perfect for 183's an 180 hybrids.My gunsmith has asked what free bore I want for my new 284 and I was hoping to try the 183 Sierras. How do they compare to the 180 hybrids or 195gn in bearing surface/free bore needed?
That will be handy. I suppose then that the bearing surface of the 195s will be too long to have a chamber set up to suit both the 183s and 195s? Has anyone here compared bearing surfaces with these 3 bullets using a comparator? I am still waiting for my 183s and 195s to arrive.My gunsmith has asked what free bore I want for my new 284 and I was hoping to try the 183 Sierras.

.050" longer than 180 hybrid, thanks for that.183's about 50 thousand longer. You can set up reamer for both 180 hybrid/183 sierra. But it would be a little short for 195's ( still work but not optimum.)
In that case, I wonder if there is actually much difference in BC once the Berger Hybrid has been pointed?Yes they are pointed very nicely. They have hit a home run with this bullet. It is very accurate. Tested in Shehane and soon to be tested in my saum.
Have not tested drop. but wind drift difference is about 2 inchs at 600 yards. That is with non pointed hybrids vs 183's out of box Both running 2850fps . But for me I'm getting tired of sorting bearing surface and pointing. I just want to pull them out of box and shoot.There are a few custom bullet makers you can do that with plus the new senar-l's from lapua. So far 183's you can do that. I still need to more testing at 1000yards to see. I will be giving a full report once my 7mm saum is complete. My Shehane's freebore is not set up perfect for these bullets so I want to wait till saum is done.In that case, I wonder if there is actually much difference in BC once the Berger Hybrid has been pointed?

How far up neck is bullet at this distance? About 1/4 ?I sent a round with the 183 to JGS to measure with the bullet approx .050 above the neck/shoulder junction. It worked out to be .225 FB.
