Balistics programs

[tlanders]

I did the OCW between 40.0 and 43.0 in 0.3 gr increments for 11 groups and 33 shots. Did two fouling shots then started the first round robin of 11. Then let the barrel cool down to the start point and did the next 11 round robin. This time I let it cool down and I cleaned it with Patch-Out. Then two fouling shots and the last round robin of 11 shots. My good groups occured every 1.2 grs. 40.0-40.3, 41.2-41.5, and 42.4-42.7 with 41.8 a great group but the node was at 10 O'clock. The nodes of the other great groups moved around and I could not find what you were wanting - three consecutive groups with the node in the same spot. The 40.0 was 1/8" off center at 3:00. the 40.3 was 1/4"off C at 4:30. The 41.2 and 42.4 was similar to the 40.0 and the 41.5 was similar to the 40.3 - the 1.2 gr connection. 42.7 was 1/4" off C at 1:30. I guess I mistakenly decided to load 4 rounds each from 42.4 to 42.7 in 0.1 gr increments ( because these were the 2nd and 3rd best groups and were consecutive but I failed to notice that the 42.7 POI was at 1:30 whereas 42.4 was dead center) and shoot them from 416 yds. The 42.4 and 42.5 were the best but I was really disappointed in the 42.7. I should probably do the same thing again at 416 yds with loads from 41.2 to 41.5 because they were the only two concecutive groups where the POI was the same. By the way, using your BCs on the scenar bullet and guessing at 2710 fps, my scope elevation change at 400 yds was to be 6 7/8 MOA from Ex Bal and the 400 yard shots were right on or next to the horizontal line!!! I wish I knew how to show you these targets. I bought some equipment to measure MV (can't remember the name) but haven't taken the time to figure out how to set it up yet - there just is NEVER enough time.

The GREAT news is that my Benchmark barrel and my 68 year old eyes were able to shoot 3/16", 1/4" and 5/16" groups at 100 yds and 5/16" MOA groups at 416 yds!!! Next competition is next Sunday. Hope I get this loading and jump figured out by then. Got a Nikon 82ED spotting scope coming in tomorrow.

If you start a photobucket account post them in the forums or you can e-mail me and add the pics as an attachment.... lucas@longrangeshooter.com or lucas@shoot-farther.com  just let me know where you send them (if you send them). I was trying to plot out your groups from the description but it's not easy to tell that way as it would be with a pic. If your POI's are within 1/2" you can definately consider them as having simular POI.... If you can't get 3 consecutive groups with simular POI's don't worry too much you can still use the nodes to your advantage but they may be slightly less forgiving. I've got a competition this weekend too... I hope we can get your load figured by then (or atleast most of the way figured).

Congrats on the great groups, I knew the rifle could do it, I figured you were capable... hand loading is where it's at.

I'll take the pictures tonight. Hopefully I'll get to shoot the 41.0 through 41.6 in 0.1 increments tonight also. The 41.2 and 41.5 groups had the exact same POI and they were two of the three best groups. The 41.2 was the best, the 3/16" group.

The rifle cleans so easily - three patches of Patch-Out and I'm done. I've done the 3 patches and then put Wipe-Out in the barrel over night and there is no blue in the morning - amazing compared to my 22-250 Savage that loads up copper like mad and takes a couple nights of Wipe-Out to clean it after shooting it.

I opened up my chronograph, it's a CEM M2 and looks easy to use. Hopefully I'll get velocity readings tonight also. I'm just torn as to shoot them at 100, 300 (your recommendation) or 416 yds. The 100 yd results were readable from a POI standpoint, even the ragged big one hole ones and it takes out the wind component. However, I would like to see what they do at 416 yds!!!! I am using new cases and not sizing them, just chamfering the inside and outside of the mouth. I weighed them and they were all close.

Those Benchmark's are really something.... the care they take when hand lapping goes a long way with the finnished product. My latest Benchmark gets a little copper toward the muzzle and that's it. My other Benchmarks had almost no copper fouling throughout... they all shot the lights out, my latest barrel is no exception.

As long as the winds are fairly mild they won't hurt your OCW testing at 300yds... at 500yds they can become more of a factor. Let us know how it goes.

[tlanders]

I sent you the targets by email.

[Lucas B.]

I just checked my e-mails... didn't get anything yet  ... try again if you can.

[tlanders]

Sent you another one this morning to your lucas@longrangeshooter.com address.

The chrono works. Twelve shots of 41.6 gr H4350 with three shots each at four different jump distances. At 0.025" jump had 45 fps variation, at 0.020" had 20 fps var, at 0.013" had 12 fps var, at .004" had 21 fps. The bullets sped up after the third shot. I did one fouling shot and the first shot was the slowest at 2618, the second at 2637, and after that they were in the 2646 to 2672 range except for the 10th shot at 2626 fps? So it seems I need three fouling shots next time. The 0.004" jump looked like the best group, but the 0.013" jump had the least velocity variation. I want to load a bunch of rounds to calculate my drop charts with. I am leaning towards a 0.010 jump - what do you think? I'll send you pictures of these four groups.

I think you've got it. I got your e-mail and replied... good shooting by the way, those groups are excellent, especially for round robin shooting! Keep us posted... at long range you'll sometimes get more horisontal dispersion vs. vertical due to variations in wind... the vertical dispersion is a good indication of what the load and rifle are capable of... and in good conditions you can get it on paper that way too.

For those of you who have adopted a new Android phone, I'd recommend 'Shooter'. It's dirt cheap, allows you to store individual loads, All the basic parameters can be input and then-some (Distance, Look Angle, Atmospheric Conditions, Coriolis Effect) and also has G1 and G7 BC's. It's definitely a slick little program that's readily available on the market for d/l. I'm going to try and do a little write-up review of it at some point. Enjoy!

Man, I been reading on here the last few days and there's a lot ta take in! I see I ain't gunna do this over night but by golly I'm gunna get it in the next year! I can't afford ta go out and buy all this ballistics software and PDAs and ect.... Right now I got me a chart built and from what I've read in here so far is I need to go out and start tweeking, or should I say checking and update'n the chart. Now question is should I be save'n for a weather meter thanga-ma-bob first? I ain't got no fancy dancy phone or PDA, but my wife has been telling me I need a new phone!  Don't some of these fancy things have capabilities to have this type of software loaded on them?

Another thang, any of yas live close ta Houston?!?!! hehehe would make it easier ta learn!


Sorry, ain't try'n ta hy~jack a thread but this is where I was at when it hit me. hehehe I can't WAIT ta get home and start dialing in some ranges and shooting! MY DAYS OF OLE KENTUCKY WINDAGES ARE OVER!!!  well past 300 yards lol

[Sean P.]

LOL
PDA's are not to bad you can get them on ebay for under 100 bucks.

[psychobilly]

Yeah I been seeing that. What do ya look for in a PDA? Blue Tooth? card size? or does it just need to have a windows program on it?

I noticed that some of the hand held weather stations have blue tooth.... $$$$ big money! I figured the blue tooth would be the way to go as you could get the info from there to the PDA the quickest for a firing solution  but maybe I'm over analyzing it....

I have 50 bux in my paypal account ......  ***pb's wheels are a turning***

****edit****   

Well I have a Dell Axim X5 PDA heading to my house. lol You were right Sean, under 50 bux, 26 ta be exact! Man I hope it werks!!! So know I have ta get software huh.... and from what you have said and what Lucas posted on his site I reckon the Lex Talus Delta IV is the way ta go??? What's that gunna set me back, 200 more bux???

[Sean P.]

Just make sure the your PDA has windows mobile 2003 or windows mobile 5.0 on it or Delta IV wont work.  There is also Exbal which is cheaper and is still a good program but I am not sure what you need for a operating system.

[psychobilly]

SH*%^$ It says it has mobile 2002 premium... can I get an update on the dang thang from 2002 to 2003? My right index finger couldn't wait at 27 bux.....


EDIT

I found an update to mobile 2003, 11 bux free ship'n..... man!
