Re: New light Gun

6.5

Whats the barrel diameter at the muzzle???

It can't be larger then .950" which includes the muzzle brake if it has one on. (16 1/2Lb class)

How wide is the stock at the forend? Can't be wider then 3" for the 16 1/2" class.

What twist is it?
If it's not an 8 twist it won't stabilize the 107 gr bullets which is popular in the 6mm diameters. The smaller bullets don't seem to shoot well at that range.

Just want to make sure you are legal. If not, it will have to go into the Heavy gun class.

Re: New light Gun

Bandit, My buddy shoots a 70MK w/40grs. Varget, 91/2 primer, 39grs. H4895 will work just as well, says he's getting around 1/4" @100yds. I shoot a 75gr Sierra in my 6mmRem that shoots as good as his MKs. These aren't ideal LR loads because of their BC. I suppose your looking for something with a heavier bullet, I'd try a 95gr VLD Berger on top of IMR or H4350 or H414 powders with 40gr being your max. [img]images/icons/wink.gif[/img] Jay

Re: New light Gun

Thanks for the replies.. I didnt get a chance to actually measure the bbl but if I set a dime on the muzzle the muzzle is just a tad bigger then the dime but it is smaller then a penny so I should be good there.. The forened is under 3 inches roughly 2 - 2 1/2.. As for twist how can I can i measure that? Unless you happen to know what twist the standard bbl from Ruger is.. I asked my dad but he said he "belives" its 8 but not sure..
Also as far as im aware of this gun was never shoot @ 1000 the farthest was roughly 500 on a whistle pig..

6.5 Bandit

Re: New light Gun

6.5,
I use a cleaning rod, a wet patch on a bore brush so it fits tightly in the bore and push it down to the muzzle end. On a piece of masking tape placed flush with the edge of the guide on the rod I make a mark on top (12 O'clock) with a marker, pull the rod out and when it rotates back around to the top in exactly the same spot, the length it traveled to the edge of the tape is how many inches for one full turn. This way it is easily measured to the 1/2 inch too. As Darryl indicated, 8" is what you're looking for... you'll be luck to get that fast of twist in a factory tube... I think. I think I only have a 9 twist in the model 7 .243win I have here, maybe even a 10. Good luck. [img]images/icons/smile.gif[/img]

Re: New light Gun

6.5

The standard 243 is normally a 10 twist and will work with bullets up to around 85 to 87 Gr Match type.

I didn't know if your rifle had a different stock and barrel on it other then the factory. When you said 14 or 15lb I couldn't think of a factory varmint style rifle that weighed that much without some additional weight added.

Even a Remington 40X only weighs 13 1/2 Lbs and it has a 27 inch barrel.

I have a 243 that has never been fired in a match yet. It has an 8 twist 30 " long barrel and I have it loaded and ready if you would want to shoot it. I have shot it at 1000 yards but never in a match. It has less then 75 rounds through it. Your welcome to shoot it.

The problem could exist that, I have to go out of State Wednesday and depending on some things, I may miss the next match. It would be the third match I have missed in 16 years.
You best have another rifle ready in case that happens.

Later
DC

Re: New light Gun

Thanks Jay, I remembered crossing my fingers it was an 8, but it was not, couldn't remember exactly what it was though, didn't really matter after that though. I just remember the 100 grainers were the limit, least so it figures out that way. Anyone ever put the 107's through the 9 twists?
