Anyone using H1000 in these? Is there enough room?
Maybe we could get extended barrel life using it?
I only ask because I have a bunch of h1000 not in use. On the other hand I have plenty of h4350 and 4451 also...
Wow, I haven’t even looked at the bullet rpm with 1:7twists. Rpm is so far up there it’s scary. 349,000rpm is above my redline.
For me only wanting to run the 75 or 80eldm to about 3400-3500 I think I’ll stick to a 7.7 or 8 twist.
Thanks, I’ve played with both of those. Berger calculates out to need 1:7.5” for the 80eldm.
I see 1:8 guys shooting 80eldm fine. Thought about splitting the difference and going with the 1:7.7”
But then I could get the 1:7 and cover all bases.
You guys have me itching to build one of these.
Can’t decide on a twist or which bullet.. I will use the 80eldm or 88eldm. Suggestions welcome...
I will have to look at case dimensions but couldn’t you use a 22br for a seater die?
I have a spiral bolt knob on my Origin. Anyone have the large Tactical knob they want to trade? I want the larger tactical knob..
(Origins are 1/4-28 threads)
Thanks
I guess I’m old school, I still run a 1:8 on a Dasher. I’ve yet to find a reason for a faster one. A 105 or 108 Berger is my go-to’s.
I only ask on twist because Barnes says 1:8 for the 112gr....I’m like you though, I’d assume a 1:7 or 7.5 would get the full bc potential of the 112s.
I may go...
The 105 match burners aren’t bad either. I ran them out to 950 today with good results. Not bad for the $20 a box I paid for them.
So is everyone running the 112’s in a 1:8twist? I want to try them.
