I'm trying to get a deer hunting load put together. I am shooting a H & R 45-70
using unsized water quinched ww's 457122 hollow points weighing approwimately 340 grains lubed with LS's 2500 and winchester large rifle magnum primers using a Lee factory crimp on the top band. I have several pounds of wc846 purchased from Pats about a year and a half ago.
I didn't set up the chrono today as it has been raining and windy here while whats left of t.s. Fay is passing over.
I started with 40gr of 846 extremely squib loads at 80yds the bullet was falling short. I only loaded and shot 3 rounds. Two rounds fell a couple feet short of the target and one round fell 15 ft short. Each round had a different report. There was lots of unburned powder. Dacron filler used.
At 42gr nothing changed much. Dacron filler used.
At 44gr two rounds were the same, little recoil and fell short of the target, but one had substantial recoil and smacked the target within the 5" ring. No dacron.
At 46gr things got interesting. I thought the first round was a misfire until I saw smoke. I ejected the shell and along with it came the powder. I went back to the bench and drove the lodged bullet out of the barrel with a wood dowel. I cleaned everything up and promptly discarded the rest of those primers. I went back with three of the same load only a new box of wlrm primers. Two rounds hit the target and there was modest felt recoil. One round apeared to do the same thing, I saw smoke, but nothing, then boom it went off. Delayed reaction approximately 1.5 seconds. The spent cases had a substantial amount of smoke on the outside.
No Dacron.
At 48gr everything else remaining the same, all three fired, good felt recoil, group was the size of my fist, no high pressure signs, much less unburned powder, and a much larger flame at muzzle. No dacron.
I'll continue on when I get home from work in three weeks hopefully the weather will be better.
I don't think the primers were the problem. My friend Jeff said this powder may be sensative to reduced loads.
Has anyone here experienced this? What are your thoughts besides use another powder (my plan).
Thanks
Tim
