Looks great. Normally center to center

Load #2: 

Powder: H4350 53 grains
Bullet:  Barnes TTSX 130 grain
Velocity per shot
1.  2867
2.  2875
3.  2876
4.  2882
Average volocity:  2875 ft/sec

I had a 54 and 55 grain load worked up with all else being the same.....The group opened up substantially.  I want to try this load now with a 52 and 52.5 grain. 

Overal the group was pretty good.....  1.0 outside measurement and .85 middle measurement at the widest point.  I think I could tighten this up but not bad for first go round with this bullet.

Great groups, but I sure don't like how far off your first shot is from the rest of the group. Was that just due to a cold bore, or had you cleaned the rifle and perhaps left some oil in the bore?

Could be a lot of factors......

1.  It was cold bore
2.  No oils but did swab barrel prior to shot
3.  First shot of the day
4.  Probably the biggest factor....I adjusted my trigger pull last night to approx 2 lbs.  First shot with lighter trigger pull.

Those factory Winchester 150 grain Power Points have always shot awesome in my 270. Sometimes better than my handloads! One year for some reason my handloads just weren't grouping as good as they normally did. I shot a group with the Power Points and it was somewhere around a half inch at 100 yards. So that year I just went with the factory loads, and killed my late Entiat buck with that load (in 2004).

How bad was the 200 yard group?  What seating depth/s are you using, book length or mag length, jump/jammed?  Are you metering or weighting out each charge? Any pics of the groups?

Parallax  I think is 100 yards with that viper. Could aso be the issue

On the .270, is there a parallax adjustment on that Vortex?  Just throwing that out for some thought........ 

200 yard group were 4-5 inches, sorry did't think to take pictures.  They were all over the place.  I weighing every charge (50 grains H4350).  They are seated at 3.28" which is what worked best in my other .270.   100 yard group literally had all 4 holes touching 1/2 - 3/4 inch max.  The scope does have a parallax adjustment that was changed to 200 yard.  I played a little with the parallax today and it didn't seam to help.  I will admit I am not very well versed on parallax as this is the first scope I have ever had with a parallax adjustment. 

What powder are you using with the 243?

I am using H414 which has worked well in my wife's .243.  I have the option to of varget or H4350 currently in my arsenal. 

With parallax always start at infinity then dial down till clear. Look away then back threw the scope.  If still clear with out touching the rifle move your head around while looking threw the scope. If the cross hairs move on the target while your moving your head up or down or side to side then the parallax is not adjusted correctly.  Hope that made sense.
That varget get May very we'll be your best bet with the 243.
I would play with seating depth in both rifles. Every single gun is different, they may not like what your other guns liked

So this was probably the most help.  My guess is the scope / myself was at fault for the bad groups at 200 yards.  Today played with the parallax adjustment while at the range.  Remember this is the first scope I have ever owned with this adjustment. At 100 yards, rifle secure in sand bags, I had the parallax set at infinity.  When I moved my eyes around in the scope the crosshairs moved point of impact.  I adjusted the parallax to approx 75 yards and the crosshairs stopped moving.  I am not sure I like this for a hunting scope....but the jury is still out. 

Now that I understand the scope a little better, I will work us some more loads and hit the range again.  I will move out to 200 yards working the parallax adjustment appropriately.  My guess is my groups will tighten up to where they should be. 

This is the first year I have really used this scope on this rifle.  Before I had a vx3 4-14x50 which is now on my .308 win.  May be looking for a new Leupold soon.

That Nosler group looks great. Tho the velocity deviation  of those ttsx is nice.

I believe most scopes that don't have the parallax adjustment are set to be parallax free at 150 yards.
