playing with 10 gr Unique

[atr]

in my 35 Whelen
200 gr cast / 0.358 / 10 gr Unique / CCI Magnum / at 50 yards
first try was without polyester filler...I got vertical stringing
second try was WITH the filler....much better group

Attachment 238666 no filler

Attachment 238667 with filler about 1-1/4 square

Are you drilling out flash holes?

[Silvercreek Farmer]

I'd bump the charge a bit before messing with filler. As far as the boolit goes, what alloy, gas checked, lube?

[WehrmannsGeweher]

What doesn't it work with ?

[atr]

the boolit was gas checked, lyman #2 hardness...lub was axle grease + beeswax....
NOT drilling out the flash holes

atr, +1 on bumping up the charge a bit, perhaps 11.5gr. - 13.0gr. Unique, but with standard LR primers. While I don't own a.35 Whelen, I do use the aforementioned charge in my M 39 Finn. Nagant (Sako) with the 200gr. Ly. #314299 and standard LR primers and get excellent accuracy. Ditto for my .30-06. No filler in either instance, btw.

10 grs. of Unique is a great cast load for my Marlin 1893 38 55.

Bout the perfect powder as far as i am concerned. Oh by the way nice shooting.

Unique is the Easy Button! What kind of Whelen do you have?

my 35 Whelen is built on a Mauser 98 action with a Green Mountain barrel and a 1:14 twist. It has a Mueller "Hybrid" 3-9 scope and a adjustable trigger. Shoot the NOE 250 gr VERY well. I'm just now playing with the old Lyman 200 gr slug.

I tried 12 gr of Unique and CCI mag primers....175 C in my Ruger #1 at 50 yds....10 shots slightly less than 1" group

Being as how Unique is a rifle powder, I think you could go up a bit on the charge. I don’t have a Whelen, but a favorite load in .30-06 (straight out of CBH#4) is 18.0 gr. with a 160 gr Lyman 311672. That is the starting load and the accuracy load and shoots 1” @ 100 yds in my rifle.

Looking forward to your further exploits with Unique.

15-16 grs should get you 1500 fps, I wouldn't be using any filler with Unique powder though, or a magnum primer either.

I would not consider it just a rifle powder Lyman correlates Unique with just about every pistol cal available. Whatever you do do not compress Unique at all even with filler I had a bad situation sometime back where I had a overpressure situation. Now I don't use Unique for 45-70s anymore or any large Case

[swheeler]

Do as you wish, hope everything works out for you.

and in the words of Lily Tomlin "one ringy dingy, two ringy dingy" carry on

[35 shooter]

12 gr. Unique no filler behind a noe version of the 358009 @ 1275 FPS. shoots 1” or less @ 100 yds. From my 1/14” twist 35 whelen encore. That’s with th plain base version of that boolit.
Lubed with Ben’s Red or Ben’s BLL tumble lube.

[35 shooter]

I just used cci 200 primers in my load in my post above. Unique is a pretty fast powder... i’d Be a bit leary of using a filler with it.... just saying.
When working up my load I just made sure the powder was resting in the bottom of the case by raising the bbl. before each shot.
