I had stability problems with a 1:14 twist .22-250 stabilizing 53 gr TSXs, the group was large and the bullet holes elongated. If those 50 gr TTSXs are unstable they will show yaw on the target, you might try a 45 gr TSX which seem to stabilize in slow twist barrels. Making slight adjustments to the load or seating depth will not cure a 7 minute error.
If the bell of your scope touches the top of the barrel, that is an undesirable situation, but how it will reflect on your group size I can't say. If there is enough room between the bell and the barrel to slip in a piece of paper, it is unlikely to be a problem. If the bell touched the barrel during the mounting procedure, and you then tightened up the rings, the internal adjustments might have been damaged and a check by Korth might be in order.
When I set the scope into the rings there was clearance and after the scope was tightened down the paper would slide through, but it was very tight. But I think it was too close, I switched out with another just to eliminate one possible variable. Well that and my wife looked awful cranky when she realized I pulled the classy VX-3 off of her .257 Roberts....
Ill use the 40mm leupold and see if that helps.
The bullets going through the target werent making larger holes than the 55gr soft-points but I am still leaning towards a stabilization problem.
Yup if you look at the Barnes site the minimum twist rate recomended for the TTSX 50gr .224 bullet is 1 - 12" .
One of my friends and I were discussing the twist rates required by barnes to make them stabilize and deduced that with increased velocity of the 22-250 compared to, say a .222, there might be a chance that they would stabilize in the 1:14 Barrel. I realize that the box states 1:12, but a 1:14 .222 shooting a 50gr at 3300fps vs a 22-250 with a 1:14 shooting the same bullet at 3800 is going to be a big difference in RPM. If one looks in the barnes (Number 4) manual you will see that the test rifle they used is a 1:14 for the 22-250.
Just for clarifications sake I also would like to bring to light the fact that, although this was my first load for the gun, I purchased the gun from a friend, whom I re-load with and shoot with regularely. He had worked through several loads up to maximum on some other brands of bullets and because I had this previous knowledge, I felt confident that I could start at this high of a load. I probably should have posted this earlier, but I didnt. Just for clarity I wanted to bring this up, so all you gents dont think I'm some sort of knuckle-headed re-loader. I will admit when working up to a maximum load I do not start at the minimum, but I do start below the max with a new gun.
This is also the reason I chose to load these bullets up at the above mentioned powder charge. As having them spinning slower wouldnt make much sense. I realize the risks involved in doing it, and I know it is not recommended, but based on the previous knowledge for the gun I felt confident in doing so. As mentioned before I also want to point out that after carefully inspecting the cases there are no signs of high pressure.
Thanks again all for the advice, I am going shooting this afternoon I will post some results this evening.
Cheers!!
Eric
