200g Nosler Accubond. H1000 powder. REM 9.5 Mag primer.

So I changed my mind about using the 180g Nosler Partitions, apologies to those who were looking forward to it. I've decided to go with Nosler Accubond 200g. Hope to get back with results soon!

Looking forward to seeing those results bro!

soon bro soon. Hope the weather starts cooperating.

Finally got some testing done! Shots 4-7 have roughly a 1.75" group.

When I do tests like that, I shoot at the same point of aim for all shots. That way not only are you gathering chrono data, but you also get to see when your barrel harmonics are happy and land shots closer together. Barring that info I would explore the lower end where you have an extreme spread of 23 fps between 78.5gr - 79.4gr. I would say you are a seating depth change away from good groups somewhere between those lower charge weights.

I agree with osprey bro. Numbers look stable near the lower end at around 3000fps. Play with seating depth at 79.0 grains and I'm sure you'll find a sweet spot.

Definitely taking your guys advice. Thanks both of you. I will share the results with you guys hopefully sooner than later.

79g. H1000. I chose to shorten the COAL .015 inc. [email protected], [email protected], [email protected].

I have not loaded them yet. Let me know what you guys think.

Did you mean .010 inc? You might want to try going in smaller increments like .005 so you don't jump over a node, but you also might see a big enough difference to see a sweet spot by making bigger adjustment's and then fine tune them by going up or down a few thousandths in either direction.

 

[Jason1290]

Also might try loading groups of three at the same coal as you initially tested. Say 3 at 78.5, 79 and 79.5 and see what group is the best of those three. Then play with seating depth to fine tune.

This video makes me wonder if we're wasting time and components by fiddling with seating depth tests in our hunting rifles.
