Today's Load Testing - Vhit 135

[bullbarrel]

so perhaps I need to tweak seating depth and see if that makes much difference.

Its all about the COL

i switched powders to varget in both my 308 and .223 as its simpler keeping to one if feasible.
i kept my col in both cals and did load testing at the range.....luckily only the point of aim was off and i got thumb hole groups again.
varget is pricey but if the outcome justifies it so be it........will try it on the 8mm and 30-06 and see if that as the same outcome

I'm going through the same. Reminds me of the days of pellet testing for the air rifles. Lol
Although that was much cheaper and easier than tuning a centrefire round.

Are you using the same length as your N133 load? If so that side of things should be sorted and you just need to find the best powder weight.

I'd load up 5 rnds each of 25.1 to 25.7 at .1 gr increments.

Do you use a rear bag out of interest?

Yeah, the same Coal and I did indeed use a small, makeshift rear bean bag. Funnily enough tonight I've done exactly what you suggested there and loaded 5 rounds each from 25.1 - 25.6 in 0.1gr increments

By the way, your inbox is full

Here's the results from today's experimentation. Targets set out at 121 yards with a 7mph 45 degree crosswind. All shots were 5 shot groups:

Powder weights from 25.2 - 25.6gr



COAL adjustment using 25.1gr which I figured had the best potential following yesterday's results.



Think I'll stick with 25.1gr with a COAL of 2.290". I'm confident what little vertical stringing there was, was in fact down to me. It would've been helpful to have a finer dot to use as an aimpoint.
