Sorry, I googled that bullet -  RCBS 150 sp  - and came up empty, it appears to be obsolete, not even listed on the RCBS website that I could find.... Could you please provide a link to the BC specifications, along with it being done with the G7 Drag Model?.... I have never heard of the G7 model being used on flat-based bullets, it makes no sense as the G7 standard projectile is a boattail....



Bob
Hello Bob
This is a gas check bullet not a flat base bullet a gas check shank worked like your rebutted boat tail this is the reason for using the G7 you are 100 percent correct about the flat base not doing what this bullet does .
The .271 BC is right out of RCBS cast bullet reloading book.( no longer in print) Yes this bullet was discontinued many years ago but you can pick them up on Ebay.
I should call this the bumble bee bullet NASA says a bumble can not fly but it does just as this bullet is doing.
The flight path of this bullet is amazing
 Go to Hornady Ballistics Calculator use the advance and select the G7  for SP BT not the G1 P FB 
Glad to help

You're probably correct Travis! All I want to know is, how many shots did it take to hit the target? Once sighted in, how many hits out of say 10 made it? There is a reason I ask.

I've hit prairies dogs at over 1,500 yards more than once. I can't think of any time where it didn't take at least five tries.

After sight in 4rounds 3 hits 1 miss  first 3 hit last one miss so I called it a day,I was shooting in a 10 / 25 mile swirling wind  with down draft at base of mountain and yes in this wind it was luck and skill both.
I did try heaver bullets but with the factory 1/14 barrel the heavy bullets loose stability I can not explain why this bullet works so well but it always comes through.

David, you can't simply select G7 instead of G1 and that will magically make the bullet change trajectory.... Your numbers don't make any sense, as they exceed what is being achieved by Lapua, Barnes, and all the other long-range bullet manufacturers.... As an example, the 200 gr. Lapua Subsonic, launched at 986 fps, would only be going 695 fps at 1100 yds, over 100 fps SLOWER than what you claim for a bullet weighing only 3/4 as much....  ::) .... If you can't provide actual measured downrange velocity numbers, I will continue to doubt them....

I am very familiar with that program, David.... However, I maintain that using the G7 drag model for your bullet is incorrect.... Unfortunately, as with any calculator or program it is a matter of GIGO.... feed it the wrong data, you will get the wrong results.... Unless you can confirm that the BC, using the G7 model is indeed 0.271.... and that isn't the BC using the G1 Model.... I have no choice but to believe data from firms like Lapua and Barnes, and experts like Brian Litz.... I don't know how I can be more blunt than by saying that I simply do not believe your bullet has a lower drag than the Lapua Subsonic.... Claims like that have to be proven, just saying it is so isn't good enough, IMO....

Here is a program that converts the BC from one Drag Model to another.... http://www.jbmballistics.com/cgi-bin/jbmgf-5.1.cgi

If the BC (G1) is 0.271 (which I believe), then the BC (G7) is only 0.118 at 986 fps for a 154 gr. bullet in .308 cal.... Try that in your Hornady calculator....  ::)

If the BC (G7) is 0.271 (which I question), then the BC (G1) would have to be 0.625 at 986 fps for a 154 gr. bullet in .308 cal....

Your assumptions are spot on  BOB.........Now way that bullet ONLY looses LESS than 200 fps in 1100 yds. As you know i have shot HUNDREDS of rds near and beyond  1000 yds with air and 2 very good bullets. Both  Spitzers with GC bases. My G1 Hornady Ballistics are close with my 257's as his are in .308 using G1 model. Have  shot thru 2 chronographs at same time and get good B.C. Works well to several hundred yds as I have posted before then after 600 yds the charts don't allow enough moa and at 1000 yds need around 15-20 more moa to be dead on.

Pics below of my bullets that are just as sleek as his if not better.........85 and 92 gr spitzers in .257.

I didn't argue in the GTA thread as I have placed more lead at long distance on steel with an airgun, than he has missed shots. And to believe that bullet is any better than pics below from  MOLDS at Arsenal NOW and from ACCURATE in .457, isn't in tune with Reality.

And BOB, yes plug anything  you want into Hornady but doesn't change reality......

Bob come on out and use the sheet provided to you by me I will let you shoot the gun and we will start at 100 yards sighter dead on then you may count the clicks and shoot next target and see how close click count is ti real life we will go from 100 to 1201 targets are set up and readdy are you coming.?

Carl I will  give you the same offer I have just given Bob,
I will hand you the gun with this bullet and let you sight in at 100 yards and we will progress out to 1201  using the provided chart
I  do not believe you have put more bullets down range but you may I average over 100,000 shots per year for the last 30 years what is your shot count per year?

I do believe the proof is in the recovered bullets you have perfect mushroom bullets at what distance?

NO WAY the bullets were recovered at 1108 yards your bullet has to be falling downward from over 200 feet above target with a .257 ?

what is your trajectory at 1108 yards very simple question.

I do not see this in the recovered bullets you are posting here, I see a slight downward smear on bullets nose there is no way they were recovered at 1108 yards unless you were 100 yards below said target? 

My bullet fragments show they are coming from a above angle the fragments were collected at the 1107 target which plainly show bullet coming into target from a above angel.

I do believe it is funny you chose this forum to call me a phony .
Well the ball is in your court you have the invitation are you man enough to take it ?

No, David, I will not be coming, I am a retiree on a limited and meager income.... but thanks for the invitation.... I await some genuine Chrony results for your bullet to PROVE that the BC is 0.271 or better using the G7 model.... Otherwise, I refuse to believe it is better than any other bullet out there, even much heavier boattails such as the Lapua Subsonic.... which you claim to be beating by over 100 fps at 1100 yards....

 The simple answer to all this is to send said bullets to a third party for testing and there you have it.......Im sure we can find someone....

David,

I will answer some  of your quotes........"I  do not believe you have put more bullets down range but you may I average over 100,000 shots per year for the last 30 years what is your shot count per year? "

I said i have shot MORE LEAD ON STEEL WITH AIRGUN at  DISTANCE!!   You make lead bullets and MOST ARE NOT SHOT WITH THE TEXAN or and airgun..... I have been shooting for 67 years, Last 30 at 1000 yds, from 50 bmg at RATON NM at yearly championship matches. Also F-Class. I just shoot and have no idea of the tens of thousands of rds shot.

"I do believe the proof is in the recovered bullets you have perfect mushroom bullets at what distance?"

Picture says. 1065 yds and other pic I found was 800 yds. Beyond 600 yds on steel perfect mushrooms. Below 600 yds it is DUST

""what is your trajectory at 1108 yards very simple question.
I do not see this in the recovered bullets you are posting here, I see a slight downward smear on bullets nose there is no way they were recovered at 1108 yards unless you were 100 yards below said target""

Yes my impact zone is maybe 35 feet above firing line. On the bullets you question, on steel plate (1065yds) i set plate leaning forward to deflect bullets DOWN,  as a prior trip plate was verticle and when I got home  video was glared out as sun on white paint washed it  out. On the next time out, and is 140 mi trip to my long range, I did tilt steel plate just a tad to far forward of verticle, and it sent hits right to the base and as you suggest they dropping in exaggerated the degree. About 35*angle, dropping in and plate FORWARD LEANING. I include a FRAME from Video of 1108 yd bullets, watch video and at end I shoot them in dirt.

At 1108 yds My  COLD SHOT 300 MOAB was at 298 MOA.

""I do believe it is funny you chose this forum to call me a phony .""

You need to COMPREHEND what you read......No where did I call you a  phony. I NEVER said you didn't make the shot. I DO NOT BELIEVE the G7 Hold Over numbers at all.......I didn't respond to all your slurs to West Coast Residents on GTA and those who didn't agree with you, as I knew that thread was headed for DELETE .

I found it funny in that GTA thread that because I wasn't at gun in video that it didn't happen... Yet you post a still of 3 shots on a plate and is exclusive proof??  For your information a camera on shooter and another at target isn't proof either.......The camera close up on target when in editing software can be timed at editing with shooter firing, and be only 100 yds .......So can be faked too.......Witnesses as you suggest.  I HAVE THEM on MOST of my videos I had one of two friends that wanted and liked to watch most times out. If you searched the 1065 yd video, at end one of my friends who was in the pits and when I radioed I was coming down he ran to look at target which is up the hillside above impact berm and is in video as I left it in. On the 1108 video first time last year the valley was so full of smoke from  all western fires. I could see impact zone with naked eye, set up and fired at zone without target up, and scope compressed all the polutants in air and could NOT SEE DUST AT IMPACT. I had witness with me.....Didn't shoot and several days later inversion layer lifted to be able to see but friend had to work and didn't have one that day.....That is fine as I started the long range quest over 2 years ago to see how far air could go. Never shot an airgun before.......When I got to 500 meters I was amazed and started setting camera at target to put on my Channel of all the Jazz/Ragtime music i had and my interested friends. After or before  shooting I show target view from the bench and how far it is. If  someone doesn't believe me that is fine. I know I did it, and my friends have seen me do it and I am satisfied as I did it  to please ME!! And then I shared with others.......At 76 yrs old I don't much care....

Why would I care to drive and see you do it. I know it can be done and soon I will be to 1000 yds with my .45 TEXAN and 384 gr and 412 gr bullets.....Video of 4" clays at 600 yds so far.... 

Pics i FOUND of spent hits on STEEL  First 1108 and next was 905 yds on steel.....

Cheers  Carl
