the 200eldx's- are you measuring to ogive or to tip? check that your not in to the lands at mag length
depending on how old they are Hornady had a few issues with differing ogives on some of the early batches and was screwing with my loads too.

These are fairly new, definitely weren't jammed into the lands, I measure to the ogive.
My jam or ogive measurement is 2.300" I was seated at 2.244" so effectively 56 thou off the lands not close by anyone's standards
The new ladder I had to work backwards as I only had a COAL measurement of a factory loaded round which was 2.875" COAL which worked out at 2.165" ogive.
Ughhh new barrel and new brass.....I'd rather workmwith a fouled barrel and 2x or 3x fired brass
Tomorrow is a new day and I'm confident I'll get to the bottom of things

Have you got GRT? Those numbers are putting you at the upper limits of your pressure at 60.5grains 2209 and thats about predicting 50fps slower than your getting at 2677.
Have a play, because if its pressuring like this at this cold, summer will be fun.

Funny enough at 60.5gn I was getting 2652fps with an ES of 21fps so your not far off the money.....I think part of my issues with weird spikes is due to inconsistent sizing of the new cases, after tomorrow's ladder will try annealing the once fired cases and resizing them.
In answer to your first question no I don't have GRT

Funny Hornandy load data shows a max load of 61.7gn of h4530 which is 2209 equivalent as far as i know.
