Hope I explain this right.All I ever read or hear about is the use of cast bullets when using Unique for lighter plinking loads in rifles, why can't we use jacketed bullets? Is there a danger or something?
Yes a good powder for those loads....maybe the "best powder"....but I don't want to buy another powder just for these plinkers.SR4759 was developed for reduced loads with jacketed bullets. (so I've read) I use lots of it in this application, starting at 19g in a full size cartridge like your 303, I've gone up to 21, haven't needed more than that to achieve good accuracy.
Very soft shooting.
I've been doing it for years. I can't remember which magazine published the article it was a long time ago. I have loaded Hornady and Speer 100gr. short jackets with 9 to 15 gr. Unique in .308 Win. It was perfect training ammo for my son. He took his first whitetail with confidence. Like most of us he never noticed the bark and bite of the full power 150 BT load when shooting at game because he didn't have to get beat up by it in practice. I loaded 100gr HP in .280 Rem. with 15gr. Unique. The average velocity of 5 rounds was right around 2000fps. max dev. was less than 50 and accuracy at 50 yds. was less than an inch. Many owners of wildcat calibers have also been using Unique, Green Dot, and others for fire forming loads. I use 12gr. Unique in a 22-6mm Ackley Improved with a 55gr bullet to fire form necked down 6mm Rem brass to the new chamber shape. The fire forming loads shoot as good at 100 yds. as the real loads!! I've also used this load with a 55grHP for short range groundhog hunting. I would like to here from someone who has tried it with some heavier bullets in the .243 to .30 cal. rifles.All I ever read or hear about is the use of cast bullets when using Unique for lighter plinking loads in rifles, why can't we use jacketed bullets?
