If you were to design a wildcat, what would it be?

[kentrek]

I believe you could get an extra 100 fps out of the 270 ultra...i don't have one yet but have eyed that caliber for awhile....i believe York or Jay shark has built one tho 

[bearpaw]

Allen claims you can get 3900 with a 110 gr bullet, that would be an awesome flat load for mid range. I couldn't find possible velocities for a 270 RUM?

[JDHasty]

When Kirby Allen was frist building me a rifle I was going to go with his 277 Allen Mag which is a 338 Lapua, improved to his shoulder, necked down to .277 but the supply of 169.5 Wildcat bullets ceased to exist so went with a 300AX for the, new then, 230 Bergers.

But, with Berger now offering a 170gr high BC 270 bullet, a 270-338 Lap. Imp. could be a lot more fun.

A few years ago I talked to Kirby about doing a joint venture on a 375-416Barrett with Kirby's proprietary taper and shoulder angle.  I thought it could be a fun project and give a sizable increase in velocity over the 375-408 CHEYTAC imp. stuff but he didn't think the increase would be substantial enough to warrant the expense.  I still think a 375-416 Barrett Improved would be pretty cool.  There was a guy over on long range hunting dot com that assembled the parts and pieces to build one but if I recall he developed health issues and it never progressed beyond him getting all the stuff to build it.

I checked out some potential ballistics, this is interesting!

Kirby is an interesting cat, he is married to my cousin.  He has logged every bullet he has sent down range going all the way back to when he was a kid.  I have some prints of his artwork (a mule deer and a bighorn print, I wish I had more) it is in extremely high demand and sells for a pretty penny these days, it has been decades since he has done any artwork, gun smithing takes up all of his time.

I've been dissecting his website, he has done some interesting research and development!

I have been waiting for the 900nitro-22 to come out. Can you imagine a 22 bullet traveling about 200,000 miles an hour? Or maybe just to save on powder when reloading, the dreaded 22-900 Nitro. Small shell shooting a 900 grain bullet in a rim fire. Probably only good at short range. OH and you didn't specify what you meant by a wildcat, if we are talking animals. It would have to be the "Sidehill Wampus cat"

 I plan on building a 7mm/300WSM for my next project, here is a good write up on one in the UK. http://www.6mmbr.com/gunweek071.html

[quarterstaff]

Believe it or not I would like to do something with a 215 grn woodleigh  .303 bullet and maybe a .404 jeffery case or 375 H&H case i have a P-14 action just waiting for a barrel

I pushed the 150gr bullets up around 3500 fps and the 140s to about 3600 with the 270 Ultra. The barrel I had was a 10" twist though and I wasn't really happy with it. I need to get around to ordering an 8" twist so I can really see what the 270 can do with the new Bergers. They should hit an easy 3350 fps.

Id think this would make the perfect "packable" long range gun, how was the recoil on the rifle you played with ?

I've also been looking at some 7mm options to try and get ballistics like these.

I'd have to search around and find it but I think I read where the 180 Berger was still outperforming the 195 Berger, at distance, because the 195's would pressure out and the velocity/BC wasn't enough to surpass what they were getting with the 180's.

If I recall there were a couple people that experienced this.  Maybe Travis will read this and comment because I think he was part of that conversation too.

I've encountered this before, but with slightly lighter bullets. In my 284 Striker, I get better performance out to 1300 yards using the 168gr VLD instead of the 180 VLD because of the higher velocity of the 168. I think the super heavy 7mm bullets are at their best in cases the size of the 7mm RUM and up.

My rifle was a bench gun and weighed nearly 18# scoped. The 270 RUM barrel was 28" and a straight taper to .85" at the muzzle with no muzzle brake. I was able to spot my own hits past about 300 yards and recoil was like a 308. In a 9# rifle I'd expect the recoil to be snappy, but not unmanageable. I've been really tempted to build a 270 RUM hunting rifle in the 9# range. It would be a pretty awesome "do all" rifle.

[Reidus]

How about a subsonic 50 Cal that shoots the 750 gr A-max. Shorten up a wsm case and neck it down to .50.

9# scoped would be ideal...my problem is justifying the cost right now when I hardly ever shoot game over a couple hundred yards    need to add a pronghorn hunt to my fall schedule 

[yorketransport]

I've been working on a new idea for a few days now. I need somebody to make me some lead core 600gr VLDs in .458 diameter though.

   Necked down 50?
