155 Lupua Scenar in a 1-10 twist bbl?

I have a new McGowen 20" 1-10 6 groove barrel on my Savage. With my last barrel I was shooting the 185 scenar, as it was a 10 twist too. I would like to drop down to the 155 scenar. I know its length is comparable to a 175 SMK. Has anyone ever tried the 155 scenar's in a 10 twist bbl? If so, what kind of results did you get? I know every barrel is its own beast. Just don't want to drop $50 on a box of a hundred, and it be too much twist for them.
Thank you,

They shoot fine in my 1/10

Re: 155 Lupua Scenar in a 1-10 twist bbl?

I shoot them out of a 1:12 with no issues
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

Thanks for the info, I just wanted to see if anyone else used them in a 10 twist. Before I shelled out $50.
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

graf and sons has the 155 amax for $28 plus 5.95 s/h. i've been shooting the 155 lapua in my 1/12 twist FN spr, and found the amax load up and shoot very close to the lapua. and quite a bit cheaper and a whole lot more accessible.
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

Sounds good, I will have to give some of the amax a shot. Can't go too wrong at half the price.
So below 2900? I will keep that in mind.

Thank you.
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

ive shot them out of my stock 308 savage barrel at 2950
with great accuracy
that said they do move around more than the 175/185 in the wind
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

.6moa out of 20" 5R, 155 amax. Trying out some berger moly and scenar 155's next week.

They shoot great in my 1/10.. However, I keep them below 2900 fps.

I have had a similar experience. Need to keep the muzzle velocity down or the 1:10 won't stabilize them.
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

You must absolutely screaming the 175s. They tend to get eaten for lunch on both elevation and wind by the 155.
JBM ballistics trajectory gives us:
scenar at ASC 2900 fps.

Re: 155 Lupua Scenar in a 1-10 twist bbl?

45.5 grn Varget lap brass @ 2750fps for me, fantastic accuracy but I could never seem to push them faster and keep them tight in my 26" 1/10...
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

I have a 1/10 Krieger barrel and I am running Sierra 155 palma (2156) at about 2950 with great results. I'm gettin about .7" groups at 100 as an average.
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

woodlanddude i dont know where you got those ###s
but i dont believe a 155 will be traveling at 1500 at 1000

from my experience shooting in heavy switching winds the 175/185
moved around alot less and more predictably than the 155
at all ranges
after 800 with a 308 one must use zen or voodoo

if that is what u are getting out of your 308 then good for u
i didnt get that out of mine
that being said when i shot 308 i still used the sceners, both in fclass as well in comps
quicker follow ups and less recoil
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

We have shot the 155 out to 1300yards effectively at the 3200ft to 4000ft elevations at the same course we hold the Allegheny Sniper Challenge on. I would suggest you chronograph your bullets to see what you are starting with. Altitude changes many things as well, but if you start each bullet warm for its load range, the scenar should always win. JBM matches close to EXBAL and the Ballistic whiz wheel on my data. The bullet does what it does.
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

According to Exbal, my 155's outta a 10 twist starting at 2870 fps here at 4550 ASL are still 1575fps at 1000 yards. 25.50 MOA drop.

They shoot great outta it.

I believe those numbers he posted very easily. Have shot out to 1250 with confirmed drops.
 
Re: 155 Lupua Scenar in a 1-10 twist bbl?

My experience with the 155 Scenar and 175 SMK is the 155 is a better bullet out to and past 1K. I am running my 155s @ 2900 out of a Krieger 11.25 24" barrel on 45.4 gr Varget, Lapua brass, CCI primers. The SMKs are running 2700 with 43.5gr Varget and everything else the same.

I use the exact same load, 45.4 gr. of Varget, Laupa cases, CCI BR2 primers and am getting 2,870ish FPS out of my Savage 10FP with 1:10 twist. The load and rifle are more accurate than I am. I can consistently get 1/2" groups at 100 but every once in a while I'll get one like this:
