Thanks Rick , this new area is a good idea. I shoot more paper than anything else, it's good to have a place for it at the campfire. I've been knobdicking with 210gr Berger VLDs in my heavy 30-06 recently. Ran a handful over the chrony using 60gr RL22 and was getting aound 2740 fps. Loaded up a second batch with 61gr RL22, and put them downrange yesterday, on paper at 100 yards. Results were very good. Average velocity was 2795 fps, at a quickload calculated pressure of 63k. I weighed the water capacity of my cases and factored that into the equation. Seating was set at 3.32" COL to kiss the lands. These shot very well. I put a 7-shot group on paper. A wide shot at 9 o'clock opened the group up a bit, but it was a called flyer. I think this combination will shoot consistently sub .5 moa, when I don't pull shots. 5 of 7 went into a tidy .309" c/c group. I've got the itch to try 1000yd BR, and this load just might be worthy. I'm going to roll another lot, and try them at around 500 yards. Here's pics. ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/rifles/Ogive.jpg) ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/rifles/Hellgate1.jpg) ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/rifles/Hellgate2.jpg) ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/rifles/3006_210BergerGrp.jpg) And an external ballistic calc.

Shane,
It looks like it will work. What were your extreme velocity spreads?

2771 and 2818 (48fps), with the 61gr charge. The 60gr charge was 2731-2746 (15 fps). I'm going to drop back to 60gr.

The 60 grain charge looks promising. If you haven't done this yet, you might try increasing neck tension on the 61 grain charge.
Alos, I tightened my 6.5x284 groups form 5/8 to 3/4 to under 1/2 inch by turning the necks and getting consistent neck tension.

The 61gr load is already running between 63-64k psi, I'm kinda leary about spiking it up higher by increasing neck tension.
The 60gr load runs at 60k, and seems pretty consistent on the first batch. I don't have the chamber or tools to really take advantage of neck turning. And I haven't been bitten by the bug that hard yet.
I'm going to get over to one of the 1000 yard matches at Missoula this summer, and work within the constraints of my current equipment. I know my gear is not the optimum (30-06, 10x scope, tactical stock), but it should get my toe in the water, and be a lotta fun to boot.

You can try neck tension on the 60 grain load. I too chose a low-end load for my 6.5x284. 51 grains of H4831SC gives me 2875 fps. Interestingly, if I drop the neck tnesion by using a bushing .001" larger, I lose 35 fps.......

Speaking only for myself, as one who will probably never shoot any kind of competition, I'm learning from these open discussions and information exchanges by actual competitors. Thanks for the education!

Yeah, what Blaine said.
Fact is I haven't shot in a BR competition myself either, but will this summer.

Blaine, did you go with a tight neck when you had your rifle chambered, or did you use a standard reamer? Curious to what the long range benchrest boys play with.

I think my rifle's neck is about .295, based on case springback. The reamer was marked .298, but there is no way a .298 neck would yield fired necks that measure .2935 to .294.
.295 is a good diameter for Win brass, which measures .294-.295 unturned with a 142 SMK. I have heard you want between .002 and .005" clearance between the case neck of a loaded round and the chamber.
Now there are guys who like a tight neck, like .290 to .292. There is a lot more variation in that sort of stuff in the 1000 yd game.

from a lousy, stinkin' .30-'06? you've got to be kidding, right? (hee). nice shooting, especially considering you weren't comfortably benched.
thanks for the pics, and thanks, you guys, for these new threads.
i'll probably never shoot competition but i do enjoy these discussions.
then again: 6.5x55 or .30-'06?
aarrgghh!
abiding in Him,

I shot the 60gr load at 520 yards today. Group was looser than I was wanting to see, but I blame that on the operator more than the equipment. I wasn't in a good tight position. I applied dope for an estimated 475 yards, via mildot master, and cranked .75moa left windage (didn't need it). My range "guess" was about 45yards short, so shots went low. Here's a couple pics. ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/rifles/Img_1565.jpg) ![[Linked Image]](http://img.photobucket.com/albums/v461/montanamarine/rifles/Img_1578.jpg)

Very nice groups, I would give it a try. Your groups will probably be a little better off a concrete bench that are a lot of matches.

We get wind here, but not as bad as other MT locales I've lived in more in the central/eastern part of the state.
5-10 mph is pretty normal here. It gets up in the 20s-30s with gusts to the 50s at times, but that kind of wind generally only lasts a few hours. Usually a cold or warm weather front moving in.

Montana,
The country around there just makes me drool. How come its not all white? What part of Montana are you in?
Nice shooting BTW.

Montana, try a hotter primer for the RL 22. I have great results with the CCI 250 in the .30-06 and 200-220 grain bullets with RL 22. I've tried all kinds of standard primers and they just didnt' cut it for my climate (Utah) or I got SD's of 50 fps or more. The hotter primers cured all that. Keep working that load. I think you have a winner. Flinch
