Fast burning propellant in the 30-30

[Ben]

Shot out of a 94 Win, 30-30 with the 31141.
Red Dot used as a propellant.
If you've ever wondered what kind of speeds were generated with these
fast burning propellants, this will shed some light on the issue.

I found it interesting , I thought I'd share it with some of you.

Very interesting Ben..first thing I noticed was how linear it was..there is however a slight sine curve ...the differences in velocities between charges isn't as much as I expected..

I have been using RD in my 30-06's with excellent results for a number of years...those loads were below the "go to "
13 grains..not by much . (12.7)...enough to make a HUGE difference in performance..

I'll look the chart over more carefully later

Thanks for posting..Dan

Yep, very interesting! Agree with Dan on expectations regarding vols between
charges.

If you want to see interesting load some up and change the powder position each shot, then look at chrony data and you'll see why I'm using titegroup in 3030 with pb instead of rd.

^^^^^^^^^^^^^^WHAT HE SAID.

I almost threw the towel in when the first started casting because of case position.
Shooting on the bench from bags with a Contender 30-30 and blue dot. Accuracy was acceptable, and I figured I just needed to tinker with it, loads were ok to shoot an up coming match for the time being.
Match day, chickens @ 50 all 10. Pigs @100, all 10 but group was vertical, top of back to belly line, figured it was me. Turkeys @ 150, big fat ZERO. Hits were any where from 3-4' low to that high! I tried to keep my cool for Rams @ 200. First five were the same vertical string issues but not near as bad. A light came on and for some reason powder position entered my head.
Now in Creedmoor position it can be some what of a challenge to keep the powder against the primer and get the gun closed back up with out tippling it down when loading. Got several of the last five but scattered all over.
I did a bit of tinkering and testing after that and the results were shocking to say the least. 1lb jug of blue dot with a hundred or so loads out of it. I gave it away a few years later.
Soured me on fast powders in large cases for a longgggg time. I use them on occasion but with a slanted eye.
I see a lot using them with good success. Happy for ya, but for me that is the last thing I want to think about is if I tipped gun or cars down or not.
After that I noticed how a gent was closing his TC. Pull trigger guard back, barrel tips down, extract, insert loaded round. Then he would snap his wrist to slam the barrel shut. I asked him about after a match. He said his load was position sensitive and closing that way flipped the powder back against the primer, must have because he shot clean a lot.
I got a look at his rig,frame and barrel was penned as I suspected pretty bad.

I have developed a habit of elevating the muzzle before a shot off the bench....

This may be difficult in 'field positions' however!

I shoot a lot of fast burning powder ( not all of it in a single case ) with plain base .30 cal. cast bullets.

I don't shoot in competition.

I chamber a round , tip the muzzle up to settle the powder against the primer and I'm good to go.

I'm sort of with Ben, here. However I don't elevate Can't say I'm ever disappointed with my results
Never saw substantial evidence in my shooting that shows any difference one way or another & that is with Light loads of Bullseye Red Dot American Select and Unique.

 

[300BLK]

I'm in the habit of raising the muzzle and not just with pistol and shotshell powders.

 

[KHornet]

For what ever it is worth, I store my loaded rounds Base down, and pick them
out of the box that way, and load them that way. All rifles are bolt actions, and
I believe that laying the ctg for chambering, keeps the majority to the rear of
the case. I did a test a few years back, testing accuracy loading the rifle this way
compared to tipping the barrel up for each shot. Could not tell any difference in
accuracy.

I have never had an issue with Unique.
I once had an issue with 2400 in a 45-70, a better crimp fixed that.

 

[Brad]

JSH hit on something big. Powder position issues may not show up at 50 yards. Might not until 100 yards. They really show up at 200 yards and beyond.
I shot lever action sillouhette for a few years. 50 and 100 were pretty easy to hit 10 of 10. At 150 and 200 the vertical got me pretty bad. I wasn't smart enough to understand at the time what the issue was. Looking back even at 100 some vertical dispersion was showing up.

 

[Ian]

Yep. One thing about opinions based on experience is that we don't all have the same experience. I'm sure glad Rick and 44man got me to stretch the legs of my revolvers, I learned a lot and there are certain powders I just don't use any more because of what that taught me. The same is true of rifles, unless your load is good at 300 yards, it may not be what others would call good. I've watched a lot of 50-yard, tack-driving rifle loads fall apart at 100, and 100-yard groups grow many times their size at 2 and 3 hundred.

 

[JSH]

Ian, on the same note on the opposite end.
Buddy of mines Palma rifle is just crazy accurate. Yet at 200 and under about 4" group is normal.
We did some tinkering with it mid week. Had a match on Saturday. He did not have time to get it back on paper, so he volunteered me. Shot at 50, then went to 200. I was scared to death,thought we had messed it up. Called him and told him. Oh it always was like that. Get it on paper and it will be fine.
Got to the match and a few clicks of fine tuning, all was good.
Dangedest thing I ever saw.
And to watch bullets what they do from 200-600 is just insane. Yes you can see them in flight.

Some projectiles/loads take some distance to stabilize. I have been shocked by this phenomenon in the past. It still surprises me on occasion.
