The general rule for Barnes Xs is 50/1000s of the lands. does anyone know if this applies to XLCs the coated bullets. I just took some measurments in pre-64 Model 70 and 50/1000 off the lands with a 168 grn XLC would give me a COL of 3.220. Now I know that "standard" COL don't me a whole lot but I see lots of 06 COl specs at 3.250 and SAAMI max is 3.34. 3.220 just seems short...they even look short.

Anbody have experience with Barnes XLCs and their seating depth vs regukar Barnes Xs?

What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Hey Mike

Just mic'd some loaded TSX in 168 grain and it is 3.287". I use a Stoney Point and seat them back .05" from whatever measurement I get with the comparator.

Have some XLC's and some TSX's in 270 so I measured them and they are exactly the same, .6765". I think that Barnes uses the same shape for the XLC's and TSX's.

Out of curiosity, why do you load XLC's and put up with all that blue crap in your seating die and in your gun and shoot a bullet that has a reputation for being inaccurate when you could load the TSX and get the same performance in a bullet that is becoming known as very accurate with less copper fouling?

The only pre-64 I have is a 264 and my COL is 3.17" with a Barnes TSX and the book says 3.340" so I guess I have the same problem you have with the pre-64 30-06. With a TBBC the COL is still 3.255, so the book listing does not fit the pre-64's we have. Maybe they have a short throat.

Mike,

I shoot the XLCs out of my .375RUM. I seat the XLCs to the "standard" COL, and get exceptional groups......no hassle w/the blue stuff either. I shoot the TSX in everything else.

I use 180gr. XLC's and I seat mine at .010 off the rifling and I get sub-MOA groups quite regularly.

I've never pushed back from that and I think I'm actually going to try it just to see but they tack-drive as they are with 79.5gr. of Reloader 22 behind them in a .300 win mag at just under 3200fps.

I've never had a hassle with the coating in my Forster Ultra Bullet Seater. EVER!

BUT, always try something new you never know, I'm going to send some 168gr. TSX down my barrel pretty soon and see what they do.

-The 30-06 is like a perfect steak next to a campfire, a .300 Win Mag is the same but with mushrooms and a baked potato-

When I seated the bullets the blue stuff got scraped off by the neck and a lot of it ended up inside the seating die. It was an RCBS die, maybe some other kinds won't have the problem, but the neck definitely scrapes some of it off and it has to go somewhere.

The literature for the TSX and the Northfork

http://www.northforkbullets.com/

say that the grooves help relieve copper galling by giving the copper compressed by the lands a place to go. Makes sense to me, but mine is opinion only.
