--------------------------------------------------------------------------------
Finally broke the code on my wildcat 6.5X47 Lapua (.290 neck turn with a Hart 28 inch heavy contour tube, jewel trigger on an old Rem 700LA action and an custom stock from the early 70s)
Finally broke the code and found something that really shoots. I haven’t found anything that has moved it until now, very little difference, good or bad. I tried some berger 140 BT Target Long Range. Not VLDs thou the BC is very close, 592 vs 613. My velocities are still well below the manuals, Quick Load or what others are reporting. This load exceeds the max recommended load but the MV is only 2840. I never saw one deviate more the 10fps. Using RL17.
Anyway, laddering up to max pressure, the load before the top, shot two, back to back 3 shot groups that were sub .5 MOA. at 200 yards. I didn’t measure them but they were well inside a single quadrant off the 2” bull circle. I would guess .3 to .4 inch center to center. I was VERY excited, with 300 rounds thru it and nothing sub .5 moa to show for it.
Excited and little time or loaded rounds left I moved to 400 and put six in a sub MOA group so I struck out for 800. Took 4 shots to get on the steel, my scope is not level (I fixed that this morning), once I hit the steel, I didn’t change anything and fired my last two rounds.
3 shots at 800 yards in 1.88 inches…. I was not able shoot LR today, wind was howling, so I can’t tell you if it was complete luck or if the gun can do that all the time.
I can tell you that today, even in high wind the 6 inch steel was easy at 400. I’ve got almost 350 rounds thru her so that may have something to do with it, as it’s well broken in. But last weekend I was still shooting MOA groups. I think I just got lucky and found a node. QickLoad was worthless with this rifle. It varies so much from expected pressure, barrel time and muzzle velocity.
Interestingly enough, this new bullet works the best with QL but still about 100fps out.
So far, every shot has been new brass, I’m down to about 40 rounds of new brass, then I get to move to the once fired brass. It will be very cool because I don’t have to resize it. The neck turned brass is just about perfect, The spring back is about 1.5 thousands and it’s just enough to snuggly hold the new round without resizing even the neck. if anything it should be even more accurate because it’s fire formed to the chamber.
Thanks tech shooter for all your help!
