....and that's without the Weaver T-36 that weighs 17 oz. I get the scope tomorrow so I'll re-weigh and double check before I do anythang drastic. I could bore a 3/4" hole through the butt with a Forsterbit....I could also cut off a good inch from the forend. The barrel is a HV contour and 20-3/4" long but I hate to mess with that. I'm splitting hairs right now. Any creative thoughts ??????

Thannks,

Wait until you get the scope on there before you do anything drastic. It might not hurt to check your scale either.:)

Is this a wood stock, if so, see where it balances. You might make it nose heavy if you drill out the butt. If that might be a problem, then have vents or grooves cut under the barrel to try and save weight. Cutting off the forend and drilling out the butt is an option.

The forend is pretty much hollowed out under the barrel.....except for a few "bulkheads". It'll be close.............

I assume you are trying to make Sporter weight at 10.5 pounds.

The culprit is probably that HV contour. It is darned difficult to make weight with a HV contour, even at 20 3/4 inches, because they could have left all of the "straight" on the blank. How much does the barrel weigh??

You are learning a lesson here. When building a Rifle that must make weight at 10.5 pounds, you have to use specific components for that application.That is why all of the major Barrel Makers furnish blanks in LV, (Sporter), contours. With this contour, you can end up with a barrel as light as 75 ounces, or as heavy 85 ounces at 21 1/2 inches.

My question would be how did you end up with the HV contour that will be hanging off of a Cobra Action. The Cobra is specifically designed to save weight so you will not have trouble in the weight department.

As for the stock, what brand is it??. You are a little non specific. Just as with barrels, all of the major manufacturers produce stocks with a 10.5 pound Rifle in mind..........jackie

Curtis,
I am afraid you have a substantial problem. Unless the stock is very heavy wood it is going to be very difficult to get 6 or 7 ounces out of it. And then you will have a very nose heavy rifle. You could possibly get the barrel fluted but that is not without its own potential problems.

Mr. Jackie,

You are so right. Now before I cry, I will say that I think I will make it. True, my plan had numerous flaws. I garauntee you one thing, I am smarter for it. I kind of shot from the hip going with short and stiff on the barrel. I knew the cobra would be a weight saver. The Shehane stock (Baby Tracker in African Obeche at Bill's suggestion) is very lightweight, 1lb.-14oz. The barreled action (Cobra/Kreiger 13.5"/20.75"/HV) is 7lb.-8oz........9lb.-6oz. so far.....trigger guard, rings/screws, buttplate, drop port funnel is just shy of 4oz. I'm going on ahead with it and will weigh it all together tomorrow when the scope arrives. When weighing in a rifle at a competition, do ya have to have the turret caps on the scope?

Yes, if I did it again, AND I will extremely soon, I will plan things a little different, not much but a bit. I'll probably put together a 30BR or PPC so that Jackie will have a force to be reckoned with. If all else fails, I will pull out my extreme catering talent in BBQ/smoked meats/crawfish boils to make everybody worry out at Tomball. My son just met a girl so he may not be on target as he usually is, but I'll step up and fill in .

I'll be devistated if this thing is not a shooter. If it makes 10.5, I'll be gloriously happy, if not, I'll punt. BTW, I shot my Savage/McGowen/Shehane 6BR today with some junk Hornady 75gr V-max loads and it did real good. Can I shoot it against rail guns in unlimited...?????

Thanks,

Curtis

While the Shehane Stock is a beautiful piece, it is really too heavy for a serious LV-Sporter effort. The trend in stocks for that purpose will generally go about 23-25 ounces. At 30 ounces, you are simply wasting 5 ounces that could be placed some where else.

That short fat barrel thing is another item that simply does not play out in the real world. I have not used a barrel on my favorite Sporter that weighed more than 77 ounces at 21 1/4 inches in over five years.

I really wish you would have asked on this Forum before diving in head first into your first Rifle. This is the one site that caters to Benchrest as it pretains to NBRSA and IBS Registered Competition...........jackie

Oh woe is me. But, being the engineer I am, I'm still kinda old school in that there is more than one way to skin a cat. I have 3 and they all need skinnin' from time to time. Now, if it turns out to be just under 10.5 or exactly 10lb.-8oz. , will I be shunned for being a goofball? You guys have have already shared a king's ransom in knowledge with me. I had thought about a Kelbly Klub or a SG&Y, or a carbon fiber.....hey, what about this? If I had gotten it dead nuts perfect the first time, I wouldn't have an excuse to start another build. Besides that, I think this forum should make new members sign a waiver that releases everybody from being responsible for making a man become addicted. I know there's help out there. Think positive, it's gonna make it.


thanks guys,

I won't even mention my first "benchrest" Rifle.

Heck, I thought "PPC" stood for Police Proficiency Course.:D

Come on out to Tomball. I guarantee you will have a great time. And discover a multitude of new ways to spend your hard earned money.

Curtis, many of us will be at the Club this week end. We are allowed a guest. If you want to come out and shoot, let me know..........jackie

Thanks again,

I'm glad heeded the advice on here and picked a used BR gun off the classifieds. At least you have the pride of putting the finishing touches on your rifle. have any pics of it yet?

I understand your problem, but it neednt nessesary be a problem. First time I tried to make LV weight for a Benchrest rifle I had Whichita 1375 action to build on. Not quite the action for that although well made and accurate. I knew it was to heavy for a LV rifle as nobady else was doing it it so I knew I had to have the absolutely lightest stock and everything else and take the difference from the barrel. I got McMillan graphite stock and had 36xLeopold.
At last I had to turn down the barrel to some contour between LV and Rem XBR at 21 inc. The rifle shot excellently and for HV I had another barrel in HV contour and weight system in the stock to compensate for the added weight in the barrel. Didnt see any difference in accuracy between those barrels although the heavier one was eacyer to shoot. Well I had to have my scope turrets off also to make weight:D

It could be an option for you to have another barrel in LV or turned down to the exact contour that would make weight and shoot that in LV and this one in HV

I can understand your liking the Sheanne stock I have been looking at that myself for some time although that would be aimed more at a custom varmint rifle than Benchrest rifle.

In my opinion a well balanced and made Benchrest rifle will shoot just as well with LV barrel as a HV one. The difference in accuracy if there is one is not there.

Can I bring my own scale to weigh in....????????:D

cwood3
02-19-2009, 03:06 PM
Well, it's tomorrow............scope arrived. It is a total of 10lbs.-12oz.

<this is where I swear a few choice words>

Well, I have 4oz. to shave off somewhere. I will have to do some thinking on this. But first I'm gonna grill some salmon and have a few beers.

curtis......:(

If your 4oz's shy, Don't use the drop port funnel, just carve out the hole and it will work fine. Drill out the butt a little, take off scope caps/turret caps if you haven't. You can also drop the butt plate for a thin piece of black foam and glue it on. Or check how much that plate weighs. Leave it off and just finish the wood. Oh yeah, gotta include finishing the wood if you haven't. I think you can make it with a little work. I would probably have some vents cut into the side of the forearm...looks nice and looses weight, also helps keep the barrel cool, shouldn't effect stiffness so much. I went through the same thing with a wood stock. Finally got it a half ounce under 10.5 lbs but not with the trigger guard, just left it off when I shot.

I took 1" off the forend, and have 2-2/3" holes approx 4" deep in the butt. Without trigger guard and buttplate.......10lb.-8oz. by my scale...it's a brand new pelouze 625SRW, analog, not digital. I guess I have to get those holes deeper, I have about 8" depth to play with.

You should have just run a pipe threading die up the barrel! :D

cwood3,
I did almost the same thing except for the stock. Was not paying attention and ended up with a barrel 21.5 long that was toooooo heavy. Finally just decided this was my dedicated HV barrel. Just load up the butt with lead when I have a HV match. Rifle will weigh about 12 3/4 lbs then. Take it out and install a proper LV barrel when shooting LV or Sporter. Just get a LV barrel and start from there. You will have to sometime anyway. They don't last forever you know.

Well, the dirty deed is done. Just got finished with the JB WeldWhen I glued her in I protected the rear threaded hole in the action with a waxed line-up pin/screw. I'm going to make a trigger guard screw just to hand tighten in the rear hole so just in case my glue job has a hiccup, the action won't leap from the stock....no tension though. I got to where she's completely assembled and make 10lbs.-8oz. If I need an ounce of leeway, I simply remove the polished aluminum buttlate/trigger guard. I have 100 rounds ready to fire.............................................. yeesh. Heavy sigh.

Yes it works
Might weigh less if the cat kept it's paw off scale !
Nice looking rifle, I hope it makes weight I dont have much faith in that type scale.

Gun shops that fill CO2 tanks for paint ball guns have certified (or supposed to be) scales to weigh the tanks when filling. They work perfect for guns...that's where I have mine weighed if I change anything.

Cwood, I took a old bag of 7 1/2 shot and put 10 lbs 6 oz in the bag using my scale. I then went to the post office with the bag and a plastic perscription bottle with about 4 oz of shot.
Put the bag on the scale, poured in enough shot to weigh 10lb 8oz and i have a permanent check weight for my scale.
Just my $.02 worth :)

Curtis, Here are some suggestions: a lighter set of rings if available, remove scope covers, hollow out inside of butt plate or shave it down if it is aluminum. Steps beyond these require more drastic measures. I would consider cutting the barrel back and re crowning. This will probably not be the only barrel on this gun and your next will most likely be a LV configuration. You could end up unbalanced later if you modified the stock just to accommodate this barrel rather then vice versa. Tim

I think I'm done. Need a second scale opinion, but I think it'll make it. Wehn I take off the buttplate and trigger guard, I pick up about 3 ounces anyhoo.....

Now she just needs to be shooted/dialed in and properly christened.........

thanks to all

I don't think you're legal with out a trigger guard in NBRSA.

I don't think you're legal with out a trigger guard in NBRSA.In another sport, I cut a strip of Coke can, rolled the edges, bent it round a lump of tube & tacked it onto the stock with a couple of dabs of superglue gel.

It passed their test.

cwood3
02-20-2009, 04:50 PM
Actually, the trigger guard (aluminum) is less than an ounce. Like I said, if I drop the buttplate (already cut a thin piece of black Forbon to fit) I'm in the money.
