I have been working on a low sd combo for this rifle for a while ( GA Precision , Schneider bbled 26" 7.5 twist sako action )

I think i am getting close [image]

[/image] I realize that it takes a lot of rounds chronoed to develop a true sd number . However if ten rounds don't get any better than a certain number I suspect that add'l rounds will not either . This load is giving 2 to 4 sd numbers at this point , as I said testing is ongoing . I will post results as they are available .( see Bob and Roy , I told you I was busy , /ubbthreads/images/graemlins/grin.gif need a sticking out the tongue guy at this point I think Roy )

I realize that this group is not a big deal for many here but for me it is a the result of a year of effort and I am a giggling 55 year old man ( unlike Roy and Buffalobob who are wheezing " I can't count that high " ooold men , oh yeah ss7mm is also in that company /ubbthreads/images/graemlins/laugh.gif )Aged and flatulent individuals ( read " old farts " )

p.s. Those squares are 1"

Let us know when you find a load that will shoot!!

 

[Fiftydriver]

Looks like your on the right track, a bit more testing and that rifle may actually start shooting /ubbthreads/images/graemlins/grin.gif!!

All kidding asside, a 1/2" class group at 300 yards is good in anyones book!! Congrats, I would stop burning up barrel life and head out to longer ranges and have fun!!

Jimm:

Hey Jim...........It's probably just that cheap chronograph you're using now that's giving you those weird, low, numbers. /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif

All kidding aside, that's pretty good shooting for an "old fart". /ubbthreads/images/graemlins/grin.gif

Here's a couple in case you need them.

I agree with what Kirby says. Quit messing around at those offhand ranges and start shooting that little thing at some serious distances and have some real fun. /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/grin.gif

Dick

you are contributing to the delinquincy of a juvenile by giving him more cartoons.

Now that he has a tiny group to post he is going to be impossible to live with.

 

[Jimm]

OK OK OK Roy ,

here is a bit further group [image]

[/image] and could you email me the little tongue sticking out guys ? I can't seem to get them any other way ( purty please /ubbthreads/images/graemlins/grin.gif )

 

[Jimm]

Sorry Dick,

Just noticed I typed "Roy " in response to your post . /ubbthreads/images/graemlins/blush.gif /ubbthreads/images/graemlins/crazy.gif /ubbthreads/images/graemlins/tongue.gif

excuse 1. the wife distracted me

" 2. the venison steaks were
burning on the grill

" 3. mental illness

Now that I've thought about it some more it was probably because I would expect such a post from Roy ! Now I know ........... there is a fourth "musket"teer /ubbthreads/images/graemlins/laugh.gif /ubbthreads/images/graemlins/laugh.gif

Jim....Jim

Jim.................

What are we gonna do with you??????

Guys...I think the only problem is that he's missing a decimal point in those yardages. It's probably more like 30.0 and 70.0 yards. That would explain the small groups. /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif

I'll sure be glad when the snow and mud goes away so I can get out and do some shooting. This cabin fever is driving me crazy.

Talk about righteous indignation /ubbthreads/images/graemlins/mad.gif I'm full of it /ubbthreads/images/graemlins/crazy.gif Young whipper snapper....

We're Old farts, eh? Even with my wheezie 63 years and buffalobob's beat up hands bet we can put ya under the table in a donut eatin' contest.....

All kiddin' aside, jimm, that's some great work. Somewhere it says; "...and it shall be given unto you, good measure, pressed down, and shaken together, and running over..." Seems to fit the results of your work (itsie bittsie groups).

Between yourself and Grit I'm feeling pretty humbled /ubbthreads/images/graemlins/frown.gif

Jimm, Nice shooting. That 300 WM load shoots very well for me also. 190 MK and 73 grains Re22 did this the other day. Maybe a little luck involved also since it was shot at 732 yards /ubbthreads/images/graemlins/grin.gif

[Buffalobob]

I guess I will have to stop badmouthing Reloader 22. Both of those groups are very flat with very minor vertical disperson.

 

[Jimm]

Nice work cowman,

What rig are you spittin'em out of ? A ten shot string with that round gave a sd of 13 . Since my ladder test showed a node that ran from 71.9 to 73.8( it ended there ) I will be loading and testing the 73.8 and 74. grain loads for sd as well. perhaps it will improve . I realize that 20 or 30 shot strings are really necessary to get accurate sd numbers , its just that if I cant get a reasonably low figure out of ten shots its not likely to improve with more .

Bob , just send me or Cowman your " floor sweepings " we'll put it to good use [image]

Jimm, My 300 is a trued up 700 LA by Wayne Forshee with a Krieger barrel, Dakota bottom metal, Jewell trigger and nestled in a McMillan HTG stock. It has proven to be a great shooter, and would make a nice LR elk rig if I ever get to go. I've got a NXS 5.5-22 with the R2 reticle on it now, great scope and easy to use. I just sent off my barrel to have a break installed. I shoot by myself and wanted to be able to see my shots a bit better. Nice work on the load development, Jimm. I do have a pound of H1000 that I want to work up a load for also. Re22 is super in the 300 but I wanted to see if I could find a load with a little more tolerance to temp extremes. Cowman

 

[Jimm]

Cowman ,

Try 74.9 grs of that H1000 under a 220smk. That load gives 2800 fps and good (.750@ 300) accuracy . At 1500 that load should be surpassing the 190 smk 100 fps and 140 or so ftlbs. The way both our 300"s like that 190 re22 load there is a good chance yours will
like the 220smk h1000 load as well. If you do try it post your results. BTW how long is your bbl ?
