thats right they are real old school pills look like a chapstick. no part number sorry. they dont make them anymore,and I missed out on the secound box Ive seen for sale.
130 grn Taipan on left, 170 grn speer in middle 150grn nosler (I think) on right.

WOW, that round nose would hit like a ton of bricks!

Reminds me of the round nose woodleigh I used to use on my 300 whisper..
Its almost a cylinder!

Had to go back to my 1964 #6 Speer book to find load data for that bullet.

awesome, thanks for that.

I really, really, really like H4831sc in the .270 with both 130 & 150gr bullets, of ANY kind.
Even my mediocre shooting skills can get sub half inch groups using it & Sierra bullets.
Lighter bullets are another thing though, with Reloder 15 doing the business.

now I really want to cry
plurry powder company rep said"no problem" when I ordered powder but now..... " sorry havent got it"
so have ended up with AR2213sc which I know is said to be the same but when I look to ADIs description of AR2213sc they say "between H4831 and imr4831
so I guess we wont ever know just what the powder companies have done....
never mind my most accurate ever load for the old girl was with AR2213sc and 130grn taipans so I guess it will be great any way. so much for trying something different .

Interestingly enough I just found this article by Steve Gash in Guns & Ammo (FEB 2013 issue) about loading for the .270 Winchester. He mentions the Speer 170 grain bullet and his load for it is 54.0 grains of AA3100, for a muzzle velocity of 2,622 ft/sec from a 22" barrel. "... it shoots superbly."

I don't see the article on their website yet.

My Schoenauer MCA .270 has a quick twist and shoots the 160g. Partitions well. The best load is IMR7828. Don't know if there is an AR equivalent or not.

have gone with 52 grns AR2213sc behind the 170 in once fired R.P. cases std win primer length to fit magazine. wont know how they group till I get a chance to go and find range area.

Elvis...AR2213sc and H4831sc are the same powder mate.
