Well I got my Chrono Monday evening.  I hope to get to the range after work today.
I hope the weather co-operates.

Well, I have definitely had better days at the range!  Everything started well, then went directly to h$ll in a hand basket!!!
 
I got to the range about 4:30pm. Sunny, little wind, no one else around.
I set up two stations, one at 100yds for the 270W and one at 50yds for the 8mm Mauser w/iron sights.  Set up the new Chrony on the 100ydr. 
 
I figured I'd warm up with 5 corelocks.  1st corelock clocked at 3083fps.  I didn't know they were loaded that hot.
2nd corelock...the muzzle blast sent the chrony flying and cracked one of the halo pieces.
Re-set up the chrony a little farther away and tried again.  Chrony again fell over.  I don't have a tripod for Chrony so I was using a fold-up TV dinner table and a couple of boxes stacked under Chrony.  About this time I hear something sliding on the shooting bench behind me and turn to watch my baby (270) slide off the sandbags bounce off the stool and hit the ground.  &$^@()%@#%*#@.  I picked her up and went over her with a fine tooth comb.  2 abbrasions on the stock one nick about 1" back from end of barrel.  *&^*@&_(&@$^%%.  Well after that I was needless to say in a BAD MOOD!
 
Set the Chrony to one side and test fired the 270.  Sure enough I had lost zero by 2+ inches left 1" high. *&%#%*.  Even better mood!  Took a 15 minute break to cool down..
 
Re-sighted in the scope using H4831SC 58gr.  She adjusted fine and zero walked right back in.  Huge sigh of relief.
 
Back to testing RE17.  Set up Chrony again, this time far enough away that muzzle blast wouldn't bother it.  Lesson learned.  Fired 5rnd group of RE17 52.7gr w/ 130gr Hornady Interbonds.  By this time light was fading fast and temp was dropping faster.
 
Speeds of RE17 @ 52.7gr w/ 130gr interbond
 
2958
2937
2929
2948
2963 fps
 
Ag 2947
Lo 2929
Hi 2963
spread 34
 
Shot a few rounds with mauser, new MoJo peepsight on rear.  World of difference!!! Thanks Dark Lord!!! Turns out mauser was set-up for 6 O'clock hold but off to left 3-4".  A couple of taps on front sight and bingo a bullseye!
 
Back to 270W and RE17
52.9gr RE17 130gr interbond Light failing fast.
1st shot 3020 fps
after that not enough light for chrony to sense bullets.
So I called it quits. Damn cold now too.
Packed up and headed for home!
 
So, if I do a little exstrapulation...
130gr interbond with 52.7gr RE17 avg . 2947fps
130gr interbond with 52.9gr RE17 spd. 3020fps could only clock one rnd do to low lite.
 
3020-2947=73fps delta.  Ballpark it to 60fps per 0.2gr increase in load
the 53.5gr load I shot last week that had POI 1.5" above zero was approxiamately cruising at 3187fps.  If I use the calculated 73fps per 0.2gr load increase that would put the 53.5gr charge at 3239fps.  I'd say that is pretty warm.
 
Weather and time permitting I will try again tomorrow to see if my reasoning tracks hard numbers.  I am posting this both here and in range report forum.

Yeah I know.  I meant to bring a tripod home from work and got side tracked and forgot.
So, I once again paid for my impatience, by cracking a brand new Chrony halo reflector and having my baby bite the dust  because I was dicking with the stupid Chrony.  I got what I deserved.  Shoot Self

Thanks 8, my baby isn't perfect anymore but I still love her!  Scratches on the synthetic stock doesn't really bother me cause I think there ugly to begin with!  But nicks and scratches on the metal really pi$$es me off!  If the shooting bench had not been covered with a layer of rubber it would have been much worse I fear!

Hey Bud what kind of scope was on there?
 
Oh, and sorry about your rough day! It can only get better from here.

Hi Trigger! 
          Gun and scope took a pretty good tumble.  Slid off bags while rotating slowly, then scope hit edge of table top.  Gun then tipped over table edge and slide down and hit the shooting stool which is really Cinder blocks capped with plastic decking. then fell to concrete floor and bounced.  All this in very slow motion while I watched wimpering.
 
No marks on scope itself but it definitely hit the table top.  Luckily the top is covered with 1/16" sheet of rubber!  Couple of good scuffs on stock and one nick about 1" back from crown on barrel.
 
Ths scope was a new 2.5-10X40 Bushnell Elite 4200.  She seems to have survived the experience well.  She dialed right back in to zero smoothly and each adjustment seemed to be a equal change. Time will tell if she'll hold zero or not. Clown

I was just curious, as my rifle took a similar tumble. Fortunately, my rifle has no marks to show for it. My scope has survived so far. I'm just hoping it is ok. It's been about 6 months so far, and lately it's been shot every day. Got to love heat waves.

If its been that long and you've shot it several different times I think it is good to go.  What brand / model is your scope?

Why do bad things always seem to happen in slow motion?  Gets sickening having it replay in your mind.  Glad nothing else got ruined.  Not bad numbers from the reload, might have to try the stuff.  Is RE17 extruded, ball, or flake?

RE17 is a new reformulation.  It is extruded and supposedly has simular burn characteristics as H4530.

budperm, why do you think the stock is too short?  Your groups show no real indication of that.  If it is really too short, you should show a tendency to group to the right of your actual POA.  There are some fairly simple Q&D formulae for determining a ROM length of pull estimate, then there is the complex science for benchrest shooters.  
 
eeeh eeem.
[/QUOTE]  Sorry guys, missed this question.
 
Well truth be told I know nothing about sizing a rifle stock.  I do know that I am a little on the oversized side of things... 6'2" 280#+ and 38" long arms.  Fairly broad shouldered.   Usually it is my arm length that gives me troubles. 
 
For instance, I was chunking for yellowfin tuna with some friends off Ocean City, MD.  I hooked into a 50# tuna and it KICKED my butt!  I was trying to hold the pole by the handle.  This meant that with my long arms  I was fighting the tuna with my biceps and small of my back.  It was embarassing!  My buddies laughed and made fun of me, after all it was only a 50# fish.
The Captain of the charter pulled me aside and told me to lock my arms out straight next time.  I said that if I did that I would be holding the pole just behind the 2nd eyelet from the tip.  He said not to worry about the Tuna stick (Pole) it would survive.  Next hook-up I did what he said and the difference was completely amazing.  I had no trouble at all fighting and landing the tuna (another 50#er).
 
I have always felt more comfortable with a longer stock and barrel.  One of these days I need to research more on how to proper fit a rifle. You guys know of any websites or books on hthe subject???
[/QUOTE]
Bend your arm to 90 degrees and place the recoil pad in the crook of your elbow.  Trigger and grip should fall right where your hand is, measure from unflexed bicep (with arm crooked to 90deg) to your normal trigger pull point.  You might have to work with that a bit and maybe get someone to assist.  Most factory rifles come with about a 13.5in length of pull, trying to meet the needs of the "average shooter".  I am only 5'8" but have a longer than normal reach(good for boxing).  My LOP is 14.25-14.5", but I can adjust for average rifle stocks.  However, IF your length of pull really is short, you should show a tendency to group to the right of your point of aim.  It is possible you have adjusted over time, but your grouping does not show that indication/tendency.  Heavy clothing tends to have an impact, which is why people should practice with the gear they are going to wear while hunting/shooting in order to get a good feel for real field conditions.  

Opinion,untempered by fact,is ignorance.

There are some who do not fear death... for they are more afraid of not really living
