Hello, I bought a Voere StLf 3 rifle in 8x68S caliber. The weapon dates from 1973 but is in excellent condition at the metal level. The wood is somewhat more drained but they are only signs of use. My "concern" is that the dream of the armory told me that the barrel had a length of 63 cm and I have measured it with a ramrod introduced by the mouth of fire and the deadbolt and the barrel length I have obtained has been of 61.5 centimeters. I would like to know if with this barrel length the 8x68S cartridge loses many benefits. You already know my usual paranoia. Thank you. By the way for shots less than 100 meters with this cartridge that best bullets the Rs Ks or the Dk. Greetings and sorry for the inconvenience.

the shorter barrel will cost you a little speed about 50feet/sec per cm what is not a problem you will have more muzzle flash and more blast not a lot of difference. bullet selection depends on game and distance to be hunted but under 100 meters i would use the DK if you want to eat the Meat.

Hope that helps

Thank you very much. There are hunting companions who have reported overexpansion with the Ks tip in short distances and consequently lack of penetration not reaching the vital organs. Especially with fast cartridges. However I have read that the tip Ks goes very well in cartridges like the 30-06 and similar in speed in the mouth.

I think 50 fps per cm is exagerated. The usual rue of thumb for Mv loss is 25fps per INCH.



Shortening the barrel from 63 cm to 61.5 cm would theoretically result in about 15 fps Mv loss. That is not significant and Mv will vary that much or more from shot to shot with any given cartridge loading.

That being said, the usual barrel length I have seen spec'ed for the 8X68S is 66 cm. Shortening the barrel by 4.5 cm would result in about 50 fps Mv loss.

Then the premise is fulfilled that the dejected piece will not know if the rifle of the one who fired was 65 or 61 centimeters. It does not seem a very significant loss of speed-energy. By the way, the benefits of the 8x68S are similar to those of the 300 Weatherby or the German is behind? Thanks.

Then I would only lose about 25-30 fps or 8 m / s approximately, which is nothing.

Las medidas del barril incluyen toda la longitud del barril, incluido el área de la cámara. En otras palabras, desde la cara del mango roscado. Lo que describiste fue medir desde la cara del cerrojo, que es más corto.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




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.

But as I measured it has its logic because the projectile will only go through the barrel from the camera or even less since from the face of the bolt you have to discount the length of the brass so that they are no longer useful 61.5 cm. Let's go to my logic that surely is wrong. Thanks for your reply. Wink

Sí, su método tiene lógica, pero no es la forma en que la industria mide el barril. Entonces las especificaciones de velocidad de un barril de cierta longitud son las que describí.

así que no tienes preocupaciones

Thank you very much Saeed I can see that the loss of speed is not significant or worrisome as the partner told me.

Could you show me how to measure the barrel by the manufacturers using a drawing or photograph? Thank you.

The length of the cartridge is included in barrel length as it contributes to the overall volume of the expansion area. It does however reduce the distance that the bullet travels. That is why the "short mags" seem to be more efficient. A 300WSM has about .75" more barrel to travel than a 300 H&H in a given barrel length.

I found this diagram of how to measure a rifle barrel. I do not know if it will be correct.

Los cañones de rifle se miden en "A" e incluyen la cámara. No se puede medir exactamente una vez que se arma la pistola. Pero como muestra en su imagen, si va 1/2 vuelta en el anillo de receptor delantero, estará cerca.
