In regards to actual Weatherby rifles not other manufacturers, is anyone reloading for these?
Agree with case life being short. I reload for the .257, 6.5-300 and 300. I recently rebarreld a 1960's German .257 to 300. I cut it off at the beginning of the lands and then machined the chamber into a cutaway. Once it was cut away I measured the bore before the lands and came up with .255. Then I measured the lands at the remaining portion of the barrel and they are at .253. Bullet diameter is .256.I load for the weatherby mark V 30-378. Too expensive to buy loaded ammo and shoot it once. $150 for twenty loaded rounds, $45 and up for 20 empty. I don't get many firings out of cases with this big guy. primer pockets loosen up quick.
Yes, a lot of them.In regards to actual Weatherby rifles not other manufacturers, is anyone reloading for these?
Are you doing any Vanguard S2's in standard cartridges like .308 or 270? I have Mark V's in .257, 6.5-300 and 300 and I have them pretty well dialed in and shooting .5 MOA at 100 yards.Yes, a lot of them.
ROFLOL... Once again, you prove you know nothing. What are you doing here anyway.One reloads for a specific rifle, not a brand. A heavy crimp like that is detrimental to accuracy.
"...the cutaway..." Isn't a rifle. It's a training aid. Every chamber is going to be different anyway. Regardless of the brand or model of rifle.
Please reduce the size of your pictures.
You are correct. The SAMMI specs for the reamer are, well, SAMMI specs. They are not consistent with my findings but they are consistent with what you would find in a third party chamber.The headspace for 257 Wby,270Wby,7Wby is same as any belt mag and one thing they have in common is same Wby free bore .378 and case length is same. Saami Spec COL will vary but for 257Wby/270Wby it's appr same 3.250" and 7 Wby is 3.360".
Case length is 2.549 and COL is 3.250".
If Wby using something beside SAAMI Spec list for Wby bore/groove they sure don't list that on reamer print.
I shot 270Wby without Wby free bore and it didn't hurt accuracy one bit. I get same velocity as Wby with free bore and I use less powder.
Bob Hutton, Tech Editor for Guns & Ammo did write up on 30-338Wby as a match rifle. Wby wasn't chamber one and Bob Hutton had Ackley chamber one of it and it has his 40 deg shoulders. They shot it at Wimbledon Cup.
std7mag, those picture 257Wby case are a shorten 300Wby case so there not blown out
I have a 30-06 and a 7 Rem Mag in non wby gen 2 Vangards. The 06 shoots about any Spitzer I feed it sub MOA. The 7 Rem mag likes C.T. 150 ballistic tips seated long on top of an over max charge of IMR 4350. Repeatedly shoots groups of 5 at 200 you can cover with a quarter.Are you doing any Vanguard S2's in standard cartridges like .308 or 270?

In most my weatherby rifles that shoot WBY cartridges, I have gotten best accuracy with no crimp.So, with Weatherby Factory ammo at 3.130, the jump from the Ogive to the lands is an incredible .700". Makes you wonder how they are so accurate. The answer I believe is in the undersized bore. I believe it swages the bullet and aligns it in the bore before it hits the lands and starts to spin. I sent an email to Weatherby to see if I was on the right track. If I am, then the number one thing you can do to improve accuracy is to ensure that your bullets are seated concentric and that the case is crimped correctly so that adequate pressure is available to do the swaging. That's pure conjecture on my part at this point. Weatherby may tell me if I right or not.
If you're happy with the way it shoots then keep doing it that way. Nosler recommends crimping on the 300 Wby but I haven't done it. I set neck tension at .001 and call it good. Weatherby roll crimps all of their ammunition. I suspect it may be because they don't want bullets falling out during shipping. I've never had one fall out but I'm not a UPS driver so I may not have the skill set to make that happen.In most my weatherby rifles that shoot why cartridges, I have gotten best accuracy with no crimp.
Yep Admin department is already there and the Gunsmithing department and testing is starting to move now. Adam is the Corporate President now. Dang he sure grew up fast. I don't know them but have seen pictures of Adam and his dad (Ed) and his Grandpa Roy. I'm headed over to Flaming Gorge in the Spring for Kokanee fishing and then I'm going to Sheridan if they have the Visitors center open by then.Weatherby is moving to Wyoming???
Yet another reason for me to move there!!-
Still trying to talk the MRS into it though...
