I have a hart barrel with Dave Kiff's .296 neck Norma reamed
chamber 1-8 tw. What load would work with 107's and
what load for 142's . I usually shoot 120's but am all out.

in a Krieger 30" 8.5 twist, 51.5 grains or therebouts works just fine for the 142. Best to start somewhat lower and work up.

Bob,

I started with 142 smk's and 51 gr 4831sc and worked to 51.5 in 1/10 inc, and every group of 5 rounds shot really well, but generally better the hotter.

I've tried Sierra 142s both jumped and jammed with success - have started using Berger 140 (the older VLDs) and am jamming them, because that's what nearly everyone advises with any Bergers.

I run the 142 at the lands. Have not tried Berger, sorry.

It has turned out that V V 165 has the nod here, .010 jump with
danzac coated 142 SMK

Bob,

Yes, I've started using N165 also. It seems to powder foul a little more than most others, but is known to be a very cool burning powder (Henry Childs, ballistics guru, found it to be the coolest burning of the many powders he measured), which should prolong barrel life - an important consideration when using the 6.5-284. I've calculated that what you pay extra in powder cost, you save somewhat more in barrel wear cost.
