I've been shooting a Taylor and Robbins bench gun made in the 1960's.
I've used cases formed from Zipper brass and Win 30-30 brass then I came across some Federal 30 American small primer cases which I had formed for my Wasp.
5 shot groups using the small primer were the best loads I've found so far for this gun.
A 52g Sierra HPBT over 28.5 of IMR 4320 with a Rem 7 1/2 primer shoots consistently in the low 2's to high 1's.
Pic of the target attached.
Here's the thread that has the pic of the gun: http://forum.accurateshooter.com/threads/taylor-and-robbins-219-donaldson-wasp.3896412/
