338 Lapua load development with 300 grain Sierra

Here are some targets from today shot at 200 yards, as you can see the weather was pretty rough, alot of rain and snow. All groups are three shots including the top left diamond (91.2 grains) which measure 5/16"!!
The 300 grain Matchking was the only bullet used at approximate velocities between 2680-2790 fps.

This PGW Timberwolf is becomming my favorite rifle real fast. [img]images/icons/wink.gif[/img] Thanks Ross.

The target on the bottom left was a mishap I accidently aimed at the wrong diamond so I drew an arrow to show were the shot would have impacted if I would have aimed at the center diamond like I was supposed to.

Nice shooting under the conditions you were under. Still thinking about having that Timberwolf chambered in 408 or are you stuck on the 338 now?

I think I will keep the 338 Lapua for a long time. [img]images/icons/grin.gif[/img]

The average of the groups above is under 1/2 moa.... there were only two groups over 1 moa.

There were quite a few unexplained fliers that really opened up my groups.

From my limited experience with these and other VLD bullets you really can't tell what they will group like until at least 200 to three hundred yards. What I mean is, that they seem to settle down and shoot even tighter out past 100 yards.

Yes, I was planning on shooting out to 1000 yards but my plans got canceled so I made do with what I had, and 200 yards was the farthest range I had. I can't wait to see what this rifle can do at very long ranges.

Re: 338 Lapua load development with 300 grain Sierra

Sheldon,
I agree with you on true VLD bullets but this 300gr bullet at 100yds will group beleive me. I don't do a lot of testing at 100yds with my bench guns, but when I do, I've produced some amazing groups and I've got 2 other buddies shooting competitively with 338 Yogis also they say the same thing about grouping at 100yds. We've fired many groups (5 shots) in the 2's and I've had a couple in the 1s when you get it tuned up properly.

But to get a load fully tuned up for 1000yd + work, you will need to test at longer ranges regardless of whether your 100yd groups are good or not. IMO.... 100yds will tell what what doesn't work but won't tell what does work at long range.

SR90,
What powder are you using for these groups?

Steve

Steve,

H1000 is the powder. As you can see I am getting a lot of one holed groups with two shots, but then my third shot is an inch away. I am wondering if it may be caused by the variations in the bullet tips. You were saying that Dave Tooley has a tool to even up the tips, do you know how much it costs.
