Freebore Hybrid 180 and Scenar 180L

[100FUEGOS]

Hello guys. I have a problem and need help with my shehane in 7mm. It comes from the factory with a very long freebore and the scenar 180L are perfect. But the 180 and 184 hybrids are very far from the ground nose and I have to go to 0.080 / 0.090 "free bore to have crimp tension ... I think it's a lot for precision (I can't find the harmonic sweet spot) . I had been thinking about the hybrid 190 from berger, but I don't have any to measure ... I already said that the 180 and 184 with freebore of 0.015 and 0.020 that in my SAUM of 7 mm go well, in the new shehane I don't get tension crimp ... and the Scenar 180 for my windy field have a low CB ... will the Hybrid 190 be long enough?

Thank you

For the Bergers I run .225 freebore for the 180-184 add .050 or so for the 190s.
180 base to ogive .743
184 bto .774
190 bto .791

My question would be have you done any testing at distance and at 100yds to see where you stand with the 180s and the 184 Bergers. I would also do some testing with the 190's
I personally don't think the extra free bore should hurt ...however testing would need to be done to confirm this. I run a 32 inch Brux .219 Neck and 240Fb...in one of my Shehane's..

My 180 hybrids only have .720 and that is why they do not crimp me and the 184 Hyb. go up to .735 also with little crimp. On the other hand, the Scenar 180L, if they set me well, they have .773. with my gauge. So comparatively speaking the 190 if they would crimp. But I don't have good competitive references on its development ... I'm thinking of a Sierra 183, but I don't have measurements. You will not have?

Does anyone, please, have the average "base to ogive" of SMK183 ????

The 183gr Sierra Match King is 1.620 long...
Its all I know and I have no history with these bullets.
I only shoot the 180 Hyb Berger.
