243 Load Test for 70 grain HPBT Moly
« on: December 02, 2012, 07:49:24 AM »
I thought maybe some would find this useful.  I used Varget, H414, H4895, and H322 for load testing.

Wow man, the difference between H322 and the others is crazy. Although H4895   has a tighter group, the H322 is closer to the bullseye on all of its hits. :ohmy

What rifle, what was the setup of this test? :confused

Use the 4895 and simply adjust the sights slightly.

That or the H414.  Rifle, scope, range, weather conditions?

Sorry, I should have given more information.  I had this rifle re-barreled in '99.  Took it to the range back then with a couple loads and shot 1 1/2" groups.  Was not happy with it so it went into the safe until a couple months ago.  I had a friend that wanted to get into shooting so I thought I would try to work this rifle with some different loads.  I am still not happy with it but it is OK.  My Remington 700P will shoot 0.3" groups and with 40 grains of H4895 with 168 Matchking HPBT.

It is a Remington 700 short action with a Kreiger barrel and custom brake.  The scope is a Nikon Monarch.  The range was 100 yards but it was sighted in at 200 yards, hence the high center point of the groups.  There was no wind that day.

Good looking rifle.  I have a stock 700 BDL that is mostly been a deer rifle up to this point but I ran some 75 grainers through it a few years back and was pleased with the outcome.  A friend told me that his .243 Ackley improved was pretty sensitive to how far off the rifling the bullet was seated.  Apparently his rifle/load combo liked a relatively short jump to the rifling - .05 - .06 generally.
