The BLR 358!!

[FOTIS]

Ron:

What is your load?

 

[CatskillCrawler]

I was selling the Leo....

Just a lil dig there! :grin:

Ron:

What is your load?

Fotis I use 48.0 gr of Varget with OAL at 2.775.

 

[FOTIS]

Velocity?

 

[rjm158]

Not sure, Fotis, I haven't had the opportunity to chrono them. I just know they shoot well out of my rifle.

Fotis I use 48.0 gr of Varget with OAL at 2.775.

Fotis, I used that same load when I first got my BLR with the 220 Speer and 225 Sierra. I wanna say they ran in the mid 2300's or so. Very accurate. I think I ran into the problem of not enough space to add more powder, so I had to switch up powders.

Compression is the issue with Varget with this size cartridge. There's nothing wrong with that load though.

Dang that's nice Fotis. Always thought that .358 as a very good round too. I would love the havea BLR like that, and then throw the 99 in the same chambering as well.

I have taken bull elk and moose, along with deer with mine. Moose at about 20yds and elk right a 200. 225gr Partitions and Sierras pushed right at a chronographed 2450fps do the trick.

Yep, and bison at 180 yards.

That is the bullet that I will be playing with...

You won't have to work too hard Fotis. Pretty accurate in my rifle and a few other BLR's I've seen.

 

[FOTIS]

I might have to pick up some Reloder 10. Been hearing good things.....

 

[SJB358]

That's a great idea. Never thought of that but it might be real good in it.

You might find it to work well. I think Scott is using 748 in his, and that has about the same burn rate as 10X. I have a lifetime supply of loaded factory silvertips for mine, so there won't be any experminting on my part. :roll: I do have a die set, but don't see a need to use it.

 

[DrMike]

I've used 10X and still work with it occasionally. I find that the old standards--IMR3031, IMR4895, W748, etc--still give me the best accuracy/velocity combination.

 

[PJGunner]

IIRC, gun writer John Barsness said he got the highest velocity from a .358 using TAC. Might be worth looking at.Paul B.

 

[FOTIS]

Got plenty of tac on hand

 

[Silent Sam]

Tac will be my next experiment. I am currently using an unpublished load of Vihtavouri. No issues just expensive and hard to find.
