What weight of .223 are you running in your Swiss Arms Classic Greens/Black Specials?

[jeffcarr88]

Hey,

Just wondering what gr. you guys choose to run in your Swiss Arms... 55gr or 62gr? I believe the barrel is 1:10 so I believe either one works BUT I am wondering if your gun tends to favor one over the other?

Thanks,

J

55's shoot nice in the 1:10. 62's are good also but I like the 55's.

 

[Recce21]

55's.

Edit: It's a 1:10 FYI

Normally 69 SMKs in my Swiss 1/10".

I tried some 70 gr Berger's and they stabilized at 50 yards. I'll run some tests out to 500 and see if they remain stable.

55 - 62 in a 1:7

60gr V-Max in my 1:10. I've managed to get groups as low as .6MOA out of these, with my handloads.

I use 55's and 62's pretty regularly, but I find the 69gr SMK's to work really nice. My rifle is a Black Special 1:10.

I see most have the 1:10 twist......
I bought mine used and it happened to be 1:7. Are they not as common for some reason?

Mostly 63 Grs, but also 55 Grs once in a while.

Thanks for the info guys!!!

What "range" of ammo can you run in a 1:10 barrel?

You can run anything from the lightest bullet you can find right up to 69 gr SMK's. I run the 69's in my 1/10" Swiss.

I did some testing with 70 gr Bergers and they seemed to stabilize just fine at 50 yards. The real question is will they remain stable at 500 yards?

If I can get the bergers to work they are a superior bullet in my mind.

BC of the Berger 70 gr VLD: .371
BC for the 69 gr SMK: .317

You don't count. You have good access to SchweizerMunitions!

I have tried the 75 gr hornady steel match and had good results at 200 m and 300 yards in both a black special and a carbine. I have tried 55 gr 62 gr 69 smk all seem to work well when i do my part properly.

Epoxy7 has Swiss military stuff that won't shoot worth a damn through his.

I know, it's unfair, isn't it

The 63 grain RUAG ammo I bought for mine shot like crap as fireball has stated. However the 62 American Eagle was 1 moa, 5 rounds 100 yards.
