Leadsled, NO! The Front and Rear rest have cordura bags that I spray w/ silicon. If you do not have your shoulder to it or your hand behind it, it will slide off of the table. Our server out here blocks Youtube so I can't get to the video to post a link. But if you will go to youtube and do a search for "Indy Shooting", you will find the video of my girlfriend shooting the Heavy at 400 yards. She shot a 10 shot 1.5" group at 400 during the video.

Yep! The only factory ammo I buy is Pistol and Shotgun! I couldn't afford to buy the guns and Factory ammo to feed them! Also they don't make factory for these Chamberings. Although .300 Weatherby is the parent case for the ATLAS, a loaded .300 WBY neck diameter is .335"! .001" to large for the Chamber. My loaded rounds are .332". The Chamber has a tapered neck, .335" at the neck/shoulder junction and .334" at the case mouth. Shooting a 210 gr. Berger VLD at 3050 fps using 79.5 gr. of REL25 and Norma Cases. I start w/ unfired Norma .300 WBY, Cheap Large rifle Primer, 14 gr. of Unique Pistol Powder, Fill w/ Cream of Wheat cereal and shake it down to the NK/Shoulder junction, then pack a 1/4 of a sheet of toilet paper to seal the case. Then spray w/ One shot case lube and fire. Out comes ATLAS. Then expand and neck turn. And you are ready.

I use the chamber to gauge the seating depth. I use a empty resized case w/ the bullet seated long and close the bolt on it. Checking for Rifling marks. Once I determine maximum cartride OAL I run this dummy round into the seater and lower the seating stem down until it contacts the bullet. Then I back the seating stem up .015". Resulting in a .015" Jam on the loaded round.
With your 270 Win., use heaviest Berger VLD that your twist rate will stabilize. Start w/ it Jammed .015" into the lands. You can adjust the seating depth once you find which powder/charge the barrel likes. Also if you start w/ a jam you can seat the VLD deeper and releave some of the chamber pressure.

I use a naked bullet and can plainly see the marks left by the lands. A Sharpie would work I guess. Your throat may be too far out to touch. If that is the case, just shoot it. Seat a fresh bullet really long and try it.

Yes the Trigger is 3 oz.! The Red one is 8 oz...
James D., She is having to shoot the gun like that because I added the outrigger that the rear rest sits on and the weight of the gun causes the table to flex if you rest you elbow on it. You would normaly adjust the rests as you look through the scope while sitting behind it. But we do shoot it most of the time by tapping the trigger. Once you adjust the rests to put the dot on the X-ring the gun does not move. The Red one is a differnt story all together. If you don't hold on it will knock your teeth out.

And yes the Heavy is quite accurate. it will shoot a 20 shot string into 2" at 400 yards. It shoot about 6" w/ 10 at 1K. The Light gun has shot 3 groups of 5 shots under 4" at 1K.
The scopes are both Nightforce. The one in the picture of the red one is in the Safe waiting on a Dasher to be finshed. It is a NXS 12-42x56 w/ the DD reticle The Red gun now has the same type scope as the Blue. Nightforce BR 12-42x56 w/ the DD reticle. The NXS has 1/4 MOA clicks and the BR has 1/8 MOA clicks which relates to 1.25" at 1000.

Bubbat,
Yes most everyone in IBS 1000 yard BR have Heavyguns like that on. There is no weight limit in HG. Weights range from 17 lbs to 100 lbs.. The current world record holder shoot a very similar chambering 187 gr. BIB bullet w/ a 100 lbs .300 Ackley Magnum. FWIW the current record is Ten shots 3.044". Yes equipment and ammo plus bench position play a big roll.

Rbelote,
I am sure that you w/ a 17 lbs Rifle can be just a competitive as anyone else. It is all about Equipment, Smith & AMMO! All we have to do is hold the DOT in the same place each time. I am very interested in trying the F-Class game. F-Class shooters are pickers. Us BR Boys are runners. We try to get all of the rounds on the target before the wind switches on use. Sometimes you win some times you don't. LR BR is shooting blind. You can't see the bullet holes from any of the previouse rounds down range. The Left port is handy though. It is quick to run the bolt w/ the right hand and have the next round ready in the left. On the LG, I don't see it as an advantage. While running the bolt, you must put your left hand on the cheek piece to keep the rifle set in the rear bag. Although it might be a fraction of a second faster having the port on the left side. I don't know! All of my LGs are RB/RP.

$5,700 Total for the LG and equipment. $ 4,435 for the LG and $1,270 for the loading and shooting equipment. To have 8K in a rifle is paying WAY too much for Smithing!
From what I have seen of Eddybo’s work, he is Jam-Up!

Sidroski,
We shoot here in Wayne Co. on a private range at the Wayne Hunting Club. It is not necessary to practice at 1000 yards. I do all of my load development at 300 or 400 yards. The IBS competitions are in TN, NC, WV, VA, OH, MO, MN & CO. Most of the ranges during the summer will not be that big of a difference than South MS, maybe in humidity. We have a 6 minute sighter period before record fire. During the sighter period you shoot at 4.5” Clay pigeons on a dirt bank. It is no big deal to get on target. No I don’t fly my guns. I drive to each match.
