6 Dasher 105 RDF/ H4350

[craigos]

impressive. how much would one loose you think out of a 26" barrel (3 inch reduction)?

Probably not too much. The heat concentrates and 12" from the chamber, so that should give you a good idea about the burn rate. I'm guessing you'll still be in the high 3000s with ease.

SavageDasher gets 3,080 fps with 30" bbl.in Dasher using that 36.5 gr. load with 105 Hybrids. I did it also but just could not hold seating depth. Any significant amount of powder less, that would not push the bullet up and the velocity dropped too much.

Thinking some people are using "creative" chronographs.

50fps can be explained away with the barrel, lot of powder, bullets bearing surface, ect.

Say what you want, imperical data doesn't lie. My rifle is running 3125fps with RDF bullets. I'm sorry yours doesn't, but that doesn't make mine false.

And I've yet to see a "creative" magnetospeed. I suppose like anything, it's possible, just not probable.

I might have to give 4350 a go in my brx. I'm getting pressure signs at a little over 31gr of varget with hybrids

When I couldn't find Varget, I tried 4320. It shot exactly like Varget with no tuning adjustment required on my tuner tuned 6BRX LR bench rest gun. I haven't seen any difference in fouling and loads are exactly as Varget.
Supposedly, 4320 is more consistent lot to lot than Varget, we will see.

3125 with 4350 in a dasher I will try that tomorrow n let you know what I see.

Don't be disappointed if you don't get those speeds. I couldn't in mine from a 30" barrel using it. My accuracy load was around 3005 fps with H4350.

Thanks James I appreciate your info if I get a chance I will see what it does give me I am at 28 long.

Just got into the Dasher Bandwagon thanks to Jerry (shoot4fun). After reading this thread, I decided to try this on my rifle using IMR 4350 instead. I figured, since IMR is a bit faster burning rate than the Hodgdon, I should start at 35 grains. I loaded 15 rounds to chronograph using 105 Hornady A-Max on a virgin hydroformed Lapua Gold brass. I'm averaging 2878 with single digit ES and SD. I can easily squeeze another grain in the case which I planned on doing next. If I can get to 3k with this powder, I will be a happy camper. I'm not too crazy with Varget.

By the way this is the old IMR 4350 in a tin can. i have 16 pounds of this thing gathering dust in my garage.

Been waiting to hear, what did you come up with in your test?
Thanks ... Donovan

My issues with IMR-4350 in a couple 6Dasher barrels were:
- to big of kernels (crunch, crush) to get speed from
- very temperature sensitive
Good Luck all the same

It has been to nasty for me to test hope to soon.

Something to ponder.... we finally got a new batch of H4350 and its way hotter than than the old batch....lots o pressure signs in a 6xc. Going to have to drop down.

Just maybe it's part of why everyone's results differ so much.

 

[wildchild]

I'm getting similiar results with that powder combo or 35 ish with IMR 4451 and the Bart's rbbt 105's.

Boy, I have shot a lot of H4350 for the last 10 years. Every lot I ever had was within 5 to 6 feet a second, it has been one of the most consistent powders I have used. How much hotter are you talking and when did you get it? Matt

 

[Cool Tool]

I'll trade you places if you want to see nasty lol.

Tom that's funny I don't care who you are. LOL

Last outing using go-to load resulted in pierced primers and bolt lift issues. Probably going to drop at least .5 grains to see. Haven't been out again. We got it within the last month...was gone again a second after our dealer got it in stock.

That can also be a sign of carbon in the throat. You didn't switch primers by any Chance? Matt

Hmmm, carbon...good idea...we'll check. Same primers.
