BC of 200g wildcat??

ss7mm What rough BC can you give me? I am curious because I would like to punch it in with the 7 WSM. I am looking at either the 180g vld or 200g wildcat. I want the highest BC bullet available though, and its obviously gonna be the 200g WC. Am curious as to what your guys thoughts on velocity might be with a 200g out of a 26", maybe 2850fps? Let me know what you guys think.

Re: BC of 200g wildcat??

at those speeds i would guess very high .8 to .9 . hopefully Richard will come out with the 250gr ULD soon and we can break the 7mm into the full digit zone!!!

I would have never thought the J4 jacket could hold up to elk sized animals but you cant argue with the results SS7MM has shown us!!!

This bug 7mm bullet seems to draw a lot of flak at times but is a hoss no less!!!

with a 2700 MV I would put it in the .800 - .840 range.
I was at a elevation of just over 2000 ft., and the temps were cool.

I would think a 200 gr bullet at 2850 in the 7 WSM would be pretty optimistic,but then Ive never owned one.The 7 Ultramag would probably be better at attaining those velocities with a bullet that heavy.

Having a good bit of experience with 7 wsm I would have to say the 200 grain wildcat is to much bullet for that case. 3000 fps is top for that case with 180's. I'd say with the 200's at max , pretty stiff load 2800 fps. I think you would be much better off shooting bullets in the 160 to 180 grain range in that case.

First off, at the velocity potential of the 7mm WSM I do not know if the standard 1-9 or 1-9.5 twist will stabilize this bullet. A 1-8 would and a 1-7 certainly would.

At +3000 fps, the 1-9 will start to work well and at +3100 fps they really start to shoot well. At the +3200 fps potential of the 7mm AM a 1-9 twist will accurately handle this bullet in most cases but thats with alot of velocity.

If you get a fast twist barrel and use this bullet as a single shot mode it would probably work very well.

Most do not realize that the 200 gr ULD RBBT has nearly identical baring surface as a 160 gr Accubond so the extra weight will not be a major issue to increasing pressures. The main problem is length and for a repeater it would not be a good choice in the WSM.

As far as BC is concerned. No idea what the true BC of this bullet is. What I can tell you is that I use a BC value of 0.910 in my Exbal program to match my 7mm AMs actual bullet flight out to well past 1000 yards.

Keep in mind this is at about 3500 ft elevation as well and at a velocity of 3200 fps.

Realistically, I would say you would top out at around 2750 to 2775 fps with this bullet in a 26" barrel out of the WSM. I do not think you would break 2800 fps comfortably in that barrel length with that bullet. This does not mean it will not perform at extreme range because it certainly will at those velocities.

250 grain 7mm? If the 200 requires a 1:8 twist where would you get a 1:6 for the 250 grain? You'd need at least a 1:6 would'nt you?
