BLC(2) for a 7mm-08

I was in the middle of the Hill country Texas and Most of the gun stores are empty of most items but I did find a pound of BLC(2)and wondered if anyone uses it in their 7mm? It was the closest to Varget that I could find.

Do you have a favorite load using 139/140 grain bullets and BLC(2) in your 7mm-08?

Hornaday in their 139 grain bullets use 43.5 grains of some type of spherical powder which I got ~2735 this time but two years ago was getting 2840 from their loads and the same rifle. I know that they are using different primers in their loads because of the different colored primers you see now??



I tried to shoot in the 760/H414 and did not get a good group. I was getting inch -inch and half and groups. The stupid me realized that the front screw had come loose and that was not helping the grouping. Frowner Interesting was They all shot about the same both 139 and old 150's bullets and the vel was in the 2720 to 2765 range for the most part. I was using Fed primers, Rem brass and loaded 46-47 grains of H414.

I had the opinion of too much fps spread in the loads.

Now to go back and do it again. Opinions.

I did use Locktite to fix the problem of a loose fit with few threads engaged. Wink

Try between 43-44.5 grains for 139 grain bullets.

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.

You can get some great velocity with BLC(2) but you get an awesome fireball eary morning and late evening, bothers some, never bothered me..Ihave found the loads for H414 and 760 are listed very mild in the 7x57 and accuracy and velocity showed up with some very max loading..Why? because the loading books load the 7x57 and 8x57 extremely mild due to the weak actions like the 95 and 96 Mauser and the single shot Remington falling blocks..

I think your loading pretty mild with the 7-08 I would increase my load a half grain at a time and find its true max, and accuracy, if your an experienced hand loader and can recognize the pressure signs..todays books are paranoid due to frivolous law suits..I find a true max then cut back a grain or two to the best accuracy load..

That BLC(2) is a great powder. I used to buy it in bulk in 8 lb. canisters + used it for everything from 223, 22-250,7-08,7X57,308, + too many others to recall.


Never mistake motion for action.
