Had a chance to try some today.
6ppc with HBN coated 68 Ultras jammed (roughly) .040". Fed 205 M's

Started with an Audette ladder at 200yds. 28.0 - 32.2gns in .3gn increments.
Temp about 22 and a whole lot more wind than I would like. Gusting to 20mph would be my quess.

The Audette started out pretty bad. Never saw my old worn out ppc shoot that bad. 1 moa of horizontal is more than I can attribute to the wind.
Right at the end the last 4 rds settled down. 33.1 - 32.2 grouped around
.350. Hard to tell as there was one other lower charge weight in that group.
Seemed like I might have something afterall.

31.3 = 3440 fps
31.6 = 3458
31.9 = 3460
32.2 = 3489
No overpressure signs below freezing.


Had lunch and loaded up the rest of the brass I had prepped. Decided I wanted to try a group just over my Audette test at 32.5gns too.
The wind actually died down quite a bit after noon. Good thing as my dog had eaten all the surveyors tape I had out:D
I moved into 100yds for groups.

31.3 = .143 (3 shots only cold barrel)
31.6 = .175 (5 shots)
31.9 = .161 (5)
32.2 = .234 (5)
32.5 = .249 (5 all shots vertical)

With foulers, Audette and groups I count 43 rds with no cleaning. Considering the age of this barrel and the faulty tigger puller anything under a .2 is darn good. I got plenty of other targets to prove that assumption:D

Sundays Match @ The Bay

Ok, Joe it sounds like you got the stuff to shoot pretty good. How about bringing it up to the Bay on Sunday.
 
Hi Russel

Is it true you guys are gonna be shooting at 200yds this Sunday?
I can honestly say with absolutely no reservations I'm no where near ready to shoot 200yd Benchrest. Way out of my league.
I must have gotten lucky the two times I ventured up there last year as both matches were at 100yds.

He!! I'm not ready for 100 either but I feel only half as stupid doing it:D

Still have no flags nor would I know what they're trying to tell me.
You see to be able to shoot in urban Ct. I need to shoot through a homemade range muffler. Cuts off any vision of surveyors tape or flags if I had them. As of yet I haven't bothered buying a set of flags mostly because I can't use/learn them at home.

Fortunately/unfortunately my home range is fairly well protected from a good deal of the wind out there. Helps me shooting without flags but at the same time I'm not learning how to deal with the wide open spaces.

Quick check of the not so reliable internet weather is calling for 30-40 mph gusts this weekend in Ct. My theory is if its bad here its twice as bad at Dunhams:D
Got any 1000yd targets kickin around? Maybe I could wound one. Give it a severe limp anyway.

I'm gonna check dunhams site to see if they've listed dates and yardages.
Still need to do some extra testing before I make the mistake of bringing preloaded ammo based on the results of one or two groups. Been there done that last year:D

Good Luck Sunday, Stay Warm (not likely:D)

Well, according to the IBS site all matches in Dunham are shot at 100yds.
Makes sense to me. Theres no lazy days under the Palm tree weather up there.

Who knows? If you see a guy show up with a Pitbull festooned with Surveyors tape thats me. His only demand in life is to stand in front of my guns when shooting. Might as well put him to good use.
He'll even pull targets too. Never pulls em after I'm done shooting them tho, always before:mad:
 
Joe,
I have a pair of Jet Black "Erie Canal Wild Cats" that think the center of my archery target is the place to be while I'm practicin' ?

The White Dunes of the Bay

You are correct Joe the winter league is all 100 yards registered match with moving backers. There are plenty of flags to use and I am sure everyone would be willing to help with any of your needs, bring the dog and come on up and enjoy the day, it looks like the sun will be shining with light winds and about 18 degrees. Bruce also puts on a pretty good spread for lunch for about $6.00 all you can eat. So come on up and enjoy the day. Now Hal what time should I have the coffee ready, we can load up all you BR stuff and we can share a ride to the match. And Joel we can pick you up where I 90 meets the NYS Thruway and don't forget the targets.
 
Russell,
Thanks for the offer,but if the Camillus-Canastota guys found out I was hangin' with the Dunham's Bay crew I would never here the end of it ! Tell Bruce and everybody "Nader sez', Hey!"

Thanks for the report and sorry about your surveyor tape!
It's interesting the velocities you got. Can you tell us what kind of Chrono you were using and how far from the muzzle was it placed?

When I chronographed XBR back in early November down in PHoenix, the temp was 70 degrees and 31.1 grains went 3388 through my Oehler 35. This was from a 22" Krieger barrel with 1600 rounds through it.

Joel, better you than me. I would hope if "Buddy"' ever sees me pull that ol bow off the wall he'd have the sense (doubtful) to head for the basement and burrow to the center of the woodpile. The reason I took up rifles is because missing the target with arrows cost to much;)


Russel

"The White Dunes of Dunham":D:D:D Now that right there is funny!!!!
The New York State Travel Bureau should be sending you royalties for that line. I'm seeing Jimmy Buffet kicking off his flip flops and sinking into "The Dunes" up to his chin.;) You sure know how to paint a pretty picture tho:D
"Light Winds?'' Does that mean the tops of the trees won't actually be kissing the tops of "The Dunes".
Seriousy tho, I appreciate your offer of assistance in the wind flag department. Its no secret shooters of any discipline will bend over backwards to help others. Thats one of the finest attributes of the shooting sports besides the big bang we get after pulling the trigger. (Freud?)
Nonetheless, while I understand I need them I would'nt/could'nt use them:confused:
I've tried watching my neighbors flags at other matches and I've even had flags in my own lane at Dunhams. I'm a slow learner I quess. Just my green opinion but I think reading flags is the hardest part of the BR game.
It takes all my mental preparation just to keep the dot in the ball. I tend to block the flags out rather quickly.
Besides, Whats all the hub bub about? I can tell you exactly how hard the wind is blowing and the exact direction right after I pull the trigger.;)

Besides there will be plenty of "Buffet fans" wandering chest deep into the dunes to put up brightly colored waving flags to keep me fully mesmerized and totally confused.
Do you have any barrel necked Saint Bernards to rescue those hapless souls from "The Dunes"?

In short (yeah right) don't worry about me. If I show up its with the intent of shooting with what I've got on hand. Underdog has always been my style:D
A philosphy that hasn't served me well so far but someday......
I'll be there Saturday. Should be much easier getting in the top ten Saturday.

Joel

I looked at the schedule. From what I saw those Cammilus/ Canastota Boys are down in the Keys enjoying an iced "Hurricane" with with a cute little Umbrella on top.
Whilst your stuck up in the New York area with the dunes blowing in from the Great Lakes, how could you resist a little trigger action. Nothing like Great lakes sand in your Gor-Tex to help you appreciate summer.
PS Just saw your name in Precision Shooting. Congratulations #6. There must be some fine shootin and flag watchin behind that number.
I'm seriously impressed by what you guys (and gals) can do at a club level.
National rankings. The dedication required is beyond my realm of thought.

Krieger 21 3/4" tube. At least 1300 rds through it plus whatever the first owner shot (never disclosed) I'm the third owner. Yes I need a new barrel;)

Chrono? Let me put it this way. I bought a cheap chrono even before I began to handload. I do things backwards yes. When my cheap chrono died I got an even cheaper (used) chrono. Traded some used 204R brass for it.
Chrony Alpha 1 Shooting chrono I think its called. You'd have to search hard to come up with a lessor unit. Its not an Oehler by any stretch of the imagination. Works only in full daylight which I seldom see in my forest range.
Sun goes down it goes down.

When I'm fortunate enough to be able to shoot under normal light conditions it does seem to work well or well enough anyways. I have noticed you REALLY need to get them right over the eyes or it will miss the shot.

Placement is a well educated quess of 10' muzzle to first eye. Construction guy, I know my footage pretty good;)

My velocitys do seem high. I havent rechecked but I think Jackie found his sweet spot at roughly the same velocity but with a higher charge of 32.4.
Why? Not sure myself. I do FL size my brass every firing with an off the shelf Redding body die. Headspace is set correctly but it does overwork the entire body reducing volumne. Not the proffessionals choice of die.
I do know that 32.5gns brings me almost to the top of the mouth in my sized cases. Throat is so long in this tube it does'nt matter. Pills are just barely hangin in there anyway.
Some conventional wisdom claims reducing the volumne of the brass has no effect as it blows out to chamber dimensions rapidly. I've seen instances where I don't buy into that theory. I've seen certain powders(any Viht) in certain cartridges (204R) with correct burn rates that meet or exceed maximum book data velocitys yet fail to expand the necks in a reliable fashion on brass. Even after annealing, Twice, three times! Turn the necks down to
.009, still no glory.
Jam em into the lands (very hard to do in a factory 204) and the problem goes away.
That 1000 + round test taught me brass does not always expand as fast as some might believe. I quess it would have something to do with the pressure curve but thats way beyond my education.
IMR 8208 is a relatively slow burner in the 6ppc,Maybe its not expanding my brass rapidly.
Could it be my hard jam?

Then theres my HBN factor. Moly, WS2 of which I've used both, reduce velocitys per given charge.
Reading the patent literatue on HBN the other night left me a little dazed.
Seems to me they claimed it raised velocitys but I could'nt find where they stated specific charge weights. I've never did my own test with HBN comparing velocity per charge weight.

I doubt any of this helped answer your question. Heres the data from 100 yd group testing. It did avg slightly lower. I've also noticed how close the numbers are on average considering the .3 gn increments.

31.3

3429
3417
3409

31.6

3439
3442
3451
3454
3437

31.9

3426
3448
3439

3426

32.2

3454
3452
3449
3442
3402

32.5 not picked up on my el cheapo chrono. Obviously I was to the right of the eyes on that last group. I personally did'nt care as I knew I was out of the node after 31.9.
Or was I ?????????? It never ends:D

Get'cherself some tubular 40W GE lightbulbs like these and build yourself a fixture to set the bulbs 1/2" above the skyscreen and parallel to it and never have to worry about the lighting again.

http://www.officedepot.com/a/products/269269/GE-Incandescent-Tubular-Bulb-Frosted-40/

Home depot or lowes has 'em, this is just the site that came up on a search.

My first fixture was simply a 6"X30" (id) boxlike frame made from 1X3 cedar with two holes @ 12" apart to put the bulbs above the eyes...... duct taped to the screens.

Don't bother with the guys who tell you it won't work due to our 60cycle AC power....... this is what Chrony sells you for 39.95 plus shipping (A fair price BTW...)

Using the chrony's under artifical light flattens 'em right out.
