Re: What do different group shapes tell me?

I started them off the lands .05 as recommended. It my get better with some adjustment but I didn't want to invest that kind of time on something that might see 20 rounds per year. It seems to be a good combination.

I can't believe what they are getting for a box of those little suckers (the .243 TSX's) not to mention the loaded Federals with the TSX's. It's ridiculous.

Re: What do different group shapes tell me?

I know what you mean. I bought 3 boxes, along with 2 boxes of 100gr. Grand Slam's and a box of 100g Sierra GameKings #1560. I figure that the prices won't be dropping, and I should have enough to last for a couple of seasons. The rifle should like at least one of those. I snagged 200 pc. of Lapua brass as well, figuring that I shouldn't have to buy any more. Once I find a load that it likes AND the verify bullet works well on deer, I'll load all the brass and be set for a while. In the .257 Wby, at under 200 Yds I really like the TSX. I had a Nosler Ballistic Tip enter a good sized doe, but not exit @ 80 Yds. She died, and I watched her run 'till she dropped, but there was no blood trail until the last 30 feet. Definately not the performance that I was expecting, but then again, she WAS pretty close for that velocity.....

Re: What do different group shapes tell me?

I was out shooting the 6mm06 today, working on a load. Two would practically be in the same hole and one would fly high on the first 5 groups. I kept adding powder and it eventually went away. I ended up with 58.5 grains of H1000 @ 3370 fps and a 3/8" group. I didn't load up any higher to see if it would get any better but I more than likely will. If it doesn't I'll be happy with what I have.

Re: What do different group shapes tell me?

something that comes to my mind is paralax. Did you make sure paralax was set properly? Lee

Lee:


None of the scopes were adjustable for parallax.

Re: What do different group shapes tell me?

I've got ladder loads with Winchester Primers, Lapua brass, IMR-4831 and 85g TSX's ready to go except the wind has been gusting between 10 and 25 mph for the past week. As soon as it calms down I'll shoot (the .243). My buddy has the other 2 rifles back at his house. He was supposed to come over yesterday, but the weather was too bad. Looking at the weather, it looks like Tuesday is the day with winds between 5 & 10 mph.
