Thread: Testing a conventional approach to load development

With a good rifle, for conventional hunting purposes, the zero-round load development is a real option

I got it today and I must admit that it took a bit of working out ( I’m not exactly the sharpest spoon when it comes to technology) .
I realise now looking at this older target that I was experimenting with that I don’t have the fields set correctly because it was set at 91m not 100m that the true distance was .
Anyway this is a 12 shot group ( 4 x 3 shots to let barrel cool ) that I shot last year as my final zero check before going Chital Deer hunting in North Queensland.
Now that I’ve got this app I’ll show the results of my next session with the Sierra 130 TMK’s when I get the chance next weekend.

Done more range shooting in the last two weeks than I have in The last two years, been good getting back into it even though the results aren't always the best, shots felt OK but I'm pretty rusty so hopefully improve with more practice

Tried some 108gr eldm out of the 6mm creedmoor, 2209 after working a ladder upto max to check for pressure loaded 10 at 1gr below max. Not the best but it is what it is. (Shots are not in order listed)

Your results mirror a lot of mine over the last two-three years and several rifles. May I ask what is the weight of your rifle? I'm wondering if I accidentally sold a couple of lightish rifles that were possibly "more accurate than me" and due to poor technique I never found what they were capable of . . . I have a few doubts about @gimp s "cut rifled premium quality" barrel theory as two of the most accurate rifles I've had over the years were button rifled. However both the best shooters currently on the rack are of the Gimp preference though!

4150 grams all up woth supressor scope etc, it's a Criterion prefit. I don't think it had done much work as it was second hand, but I will never know as I dont have a bore scope. I will keep playing around with it as it doesn't owe me a he'll of a lot but I would like to take it down to sparrohawk at some stage for a bit of testing further out so hopefully get it going a bit better, I'm pretty sure my technique could do with some work so that's why I haven't been too worried about sending a few components down range (practice)

Hmmm , it should be pretty forgiving at 4 + kgs but . . . . I'm learning all the time (and I do a lot of shooting at the range) and refining techniques/equipment (none of mine is flash, I like spending my $$ on rifles rather that accessories like bipods etc.). Recently I've been focusing on the shoulder end of the rifle, things like bag firmness, how the rifle fits on my shoulder and how much tension is in my right hand . . . All the vary POI.

The cut barrel thing. My experience with a sample of one (S&L) is that it shoots everything well, while the many button barrels I have mostly shoot something well but not everything.

So do you have some type of camera in front of yr target to give you all the data readings.Sorry I've been in the hills to long.

It done in a phone app, you take a photo of the target and mark the shots etc on it using the app.

I've got a few things I would like to try but probably not back to the range for a couple of weeks. Will report back
