Some 200 Wildcat numbers

Well I have a few numbers to start with but I was not able to graph past 100 yards because of the wind today but I will test out to 300 yards as promised. Sorry it took so long for even this data but with work and being sick the last few weeks it has been hell to say the least. Well I am using a 7mm STW in a REM sendero with a 9 1/4 twist. This rifle as over 1500 rounds through it so I was really happy at what I have found so far. I am not going to give a bc but if some one wants to figure it out with the numbers I give and post it that is fine. I will also add pic of targets later after I get them off the camera. Here is what I found today. At the muzzle I was getting 2859 FPS with a ES of 12 and a SD of 6. This is with 5 shots. Now at 100 yards I was getting 2713FPS with and ES of 5 and A SD of 2. The Elevation is 853ft the Temp was 72 the Pressure was 29.99 the Humidity was 70% and the Dew point was 61. I used a Pact Pro for the testing. I think a person could get away with a 9 twist with these bullets with a faster 7mm. I will really put this to the test when winter comes and I shoot them when it is below zero. I will probably add pics later tonight other wise monday as I have a wedding tomorrow that is 5 hours away. I would like to thank SSCoyote and Richard Graves for sending me the bullets to test!!! Hopefully I can get them tested out to 300 yards this week.

Re: Some 200 Wildcat numbers

Nobody has anything to say? [img]/ubbthreads/images/graemlins/grin.gif[/img] Well here are the pics the first one is the load I chronographed at 100 yards. That is 3 shots at 100 yards with 79 grains of Retumbo. The second group was fired at 300 yards with 76 grains of Retumbo in a 15 MPH cross wind. Not a bad group if you ask me. I was not able to test the 79 grain load as we had thunderstorms yesterday. Hopefully if work slows down I can chrongraph and shoot this load at 300 yards before the weekend. If not this weekend I will test it as long as mother nature helps me out a little. [img]/ubbthreads/images/graemlins/tongue.gif[/img]

Re: Some 200 Wildcat numbers

Dakor,

That is basically similiar results as I am getting in my 7mm Allen Mag in the standard Shilen 1-9 twist barrel.

My groups at 100 yards are a bit larger then yours but average less at the 300 yard mark. I am sure it is due to the slightly faster twist and the muzzle velocity. The increased initial muzzle velocity will generally increase 100 yard group size but the added stability of velocity and twist seems to help at extended ranges.

When the 1-7 twist barrels get here I suspect 300 and 500 yard groups will get much smaller. In fact at 300 yards in a quality rifle I suspect that quarter in your pics may cover a or at least touch all on a three shot group.

Time will tell.

For now though I am limited to my 26" test barrel but results are similiar to what you are seeing.

Re: Some 200 Wildcat numbers

Kirby it will be intersting to see how the top group does at 300 yards since I was not able to shoot it past 100 yards. If I can get an inch with it at 300 then I will be really happy. Time will tell I will keep you guys posted.

Re: Some 200 Wildcat numbers

Dave,

Richard is up to his ears in harvesting right now. I will answer your question though on the 200 gr ULDs. The first batch shipped FAST and are all gone. Richard has an order of new jackets on the way and when they arrive he says he will be sneaking in some time to make bullets.

I hope to get a pretty decent size shipment in as I have several of the big 7mm AMs on order that will be finishing up here soon and ready to ship. I will let you know what I get them in and you can order them directly through me if you want or through Richard.

Got out this morning to do some informal practice with the 7mm AM and the 200 gr ULD. THis load is out of my 1-9 twist stanadard Shilen test barrel and the load is getting right at 3175 fps in the 26" barrel.

I sighted in at +2" at 100 yards and this morning using the second mil dot down as a dead on hold the rifle is center punching 15" rocks at 745 yards consistantly!!! ITs almost to easy.

I though the big 257 and 270 AM covered ground fast and hit hard. The time it takes that 200 gr ULD RBBT to cover nearly 800 yards is unexplainable unless you see it. As is the almost obnoxiously loud "WHACK" when it lands home.

THis is am impressive bullet. I can not wait for the 1-7 Liljas to get here and see what this bullet will do at 3300 fps!!!

Good Shooting!!

Re: Some 200 Wildcat numbers

Dave I have a some info for you from Richard so can you shoot me an email? I tried to PM you but you must have it turned off and you do not show an email address. My email is
koryanderson6mm@hotmail.com
Kirby quit trying to buy up all the bullets!!! [img]/ubbthreads/images/graemlins/grin.gif[/img] J/K I know what you mean about that bullet smacking stuff hard. When I shot the one group at 300 yards a few weeks ago I was also shooting my 300 Win with 200 Accubonds going 2960fps out of the muzzle. The big 200gr 7mm bullet made a much louder smack when it hit the plywood backer that is for sure. That 200gr 7mm also bucked the wind much better. I really hope Richard builds them in a hunting jacket. I am also going to say after talking to Richard when I re barrel this rig I will be going with an 8 twist 3 groove. I hope I do not have trouble with bullets comming apart with the 3 groove.
