Re: .300 Wby help!

Thanks alot for the advice. The rifle has not had a good thorough cleaning as has been suggested, that will be my first step. The rifle has alot sentimental value to me, so I would like to get it shooting to its potetial. It is setting a Mcmillan stock, but just dropped in, nothing has been done to insure proper fit.

Re: .300 Wby help!

Couple of more points,

Take a magnifying glass and take a careful look at the crown for any burrs, nicks or gouges that would bother a bullet exiting. Getting a new crown is pretty cheap but the wait period is somewhat out of context with the price being as most smiths are pretty busy.

I am not familiar with 'dropping an action into a McMillian stock' but I would certainly want to bed almost any action in almost any stock. There is really a very good and very long thread on this site about bedding actions.

The carbon buildup can require quite a few hours with a plastic bristle brush. I alternate about every 30 minutes between Sweets and Bore Shine. That way I kill twice as many of my brain cells with the noxious fumes. Iossa is supposed to be pretty good for letting sit in the bore over night and soften the carbon up. It is a gel so it doesn't run. I am going to order some and try it being as I am lazy and hate the hard work. I try to shoot on Saturdays so I have the whole Nascar race on Sunday to clean the carbon out.

As a suggestion, if you put some geography into your profile it helps all of us understand more about what you hunt and who is close to you, etc.

Re: .300 Wby help!

Do what the others suggested - a good cleaning first -especially being aware of copper fouling.
But then if it still doesn't shoot up to snuff- I have and do work on Weatherby's all the time- got 3 in the shop now.

Re: .300 Wby help!

Here is a quick and easy way to address the fouling issue. Get some Barnes CR10 and JB non embedding paste. Start with the Barnes and you will quickly see blue if there is copper. There will be.

Wipe dry. Take a patch soaked on light oil and rub and bore wet. Put a blob of JB on that patch and run back and forth. This stuff is like toothpaste so wearing out the bore is unlikely in your lifetime. Make sure the patch is a nice tight fit.

I like to go back and forth about 30 times. Clean well with patches then use the Barnes again. A few wet patches and still lots of blue. Oil, JB, scrub some more, clean, Barnes, repeat as needed.

All this will get you back to bare metal in under 15 min.

from this point on, I rarely need to use either cleaner unless the bore gets shot a lot. I just keep an eye of accuracy and clean only as much as needed.

I would usually only use Barnes or a powder/copper solvent combo. Use the Barnes outside as the ammonia concentration is very strong - that's what does the work for you.

Another test, take the action screws out and see if you can wiggle the action in the stock. I bet you can. Get it bedded and the barrel free floated. adjust the trigger to the lightest weight you feel comfy with. Only neck size your fireformed brass. The lee collet neck die is superb.

Work up loads with bullets seated straight. I bet with some H4831SC or H1000 lit by a CCI BR2 or Fed 215M primer, behind some quality 165 or 180 gr bullets like the SST/AMAX/Ballistic tip, you will get some very nice shooting. These bullets may not be what you want to hunt with but are very accurate for testing. You could of course use a match bullet like a Matchking or Nosler comp as well.

The very first thing I'd do is get it properly bedded. My McMillan wouldn't have shot worth a damn just dropped in--in fact, it might have broke something. Of course much of that is specific to my situation, but a good bedding job just needs to be done IMHO. See how it shoots after that and go from there.

Re: .300 Wby help!

I think that alot of smith don't like to build on the MarkV because of all the lockinglugs , these take alot of time to handlap into place and I don't think that it can be done on a lathe like a Rem700 (maybe though)
But all in all they make great actions to build on they are realy strong very smooth and have that awsome 54deg bolt lift.
I have a 30-06AI that was built by Charley Sisk of Sisk guns . Its got a 3groove Lilja barrel at 26" and shoots just about everything I load in it under 1/2".
This is one of my "pretty guns" realy nice wood and super deep polished bluing.
But like every body else has mentiond go through a checklist

1)scope mounts and bases are tight
2)bore is clean
3)bedding is done right
3)crown isin't dinged up

And if all that fails have a chamber cast made you could have gotten a poor chamber or throat cut , that maybe able to be fixed bu just setting the barrel back a little and rechambering.

Re: .300 Wby help!

I'd suggest using Blue Wonder to clean the barrel first. This will get you down to the bare metal. If thats not the problem then have it bedded and check the crown. If your still not satisfied then you might try the Tubbs final finish or throat erosion products. Good luck
