300 PRC update

From a 30” barrel running 81gr of N570 Im
bw 2930 - 2960 given varying conditions. So pretty good in my book! :)
That is impressive. I run my 32" SM at 2975. I've got room to go up but I was happy with that speed.
EDIT: That's actually the same charge I'm running also.

Wow there is an overwhelming amount of info on this page!
just starting to reload for 300prc. Wanting to load 230 & 250 atips and 245 Bergers
It’s time for a new barrel, so my question is freebore. What reamer should I be going with?
I’m sure the answer is already in here somewhere, but I don’t think I can read through 106 pages lol

Thank you guys in advance

Hey All! I got lowlight to pin a thread in the reloading forum for 300 PRC loads. I had thrown out the idea of just renaming this one and moving to there but I think having a clean place just in reloading was the thought w pinning the thread there. Anyways would love some reload data over yonder! Cheers.
This thread should be edited into the OP for reference.

I am posting some reloading stuff on Rumble. I am working up 198 PVA solids with N565 and making another batch of my goto 220ELDX with 7828SSC. Not the best videos, but better than posting on the YT... I guess my main question that I have right now is will a neck thickness of 0.0135" have any noticeable difference from the brass that was turned to 0.0145"(ish)? It seems that I turned these in two different batches/settings. Would you advise going back to the thicker necks and turn them down to match the thin ones as well or would it be a waste of time?
I did forget to mention how to determine what size bushing to get or how to measure the overall neck tension (bullet diameter + neck thickness x2). I'm looking for a good quick and easy way to describe that in the next video, any tips please feel free to share.


-Spew the pew and press or cry like the rest...

Only tip is don’t get discouraged if they are .7 groups.

A few of us have played with the 30 cal PVA and none of us have found them to be .5 at 100

The 6mm shot little knots but the 30’s don’t
seem to group that tight in several different chambers

If you figure I’ll be haunting you for info

Make all your necks the same for consistency sake.
For bushing You can measure wall thickness, then double it and add to bullet diameter, after that subtract how much interference you want. If using this method I typically err on the small side just incase my measurement was a touch big.

Or, measure a loaded round and subtract the interference you want
 
I have/use a Redding Type S 3 die set plus mandrel die to load my 245/250's. The problem/question I have is: Has anyone found a better way to full length bush the neck instead of Redding's answer to insert the decapping rod set nut on top of bushing? This gets me a little over halfway down and Redding's answer is "that's good enough". I can post pics, but confident I can't be the only one with this `Issue'.

Are you trying to size the neck all the way?

Do you mean that the neck is only being sized about halfway down?

If so, I saw the exact same thing with the same line of dies - and Redding's answer is bullshit. If you're only sizing half the neck, then you're only holding in the bullet with half the friction force. This makes parameters associated with that half of the neck more important to control.

I had a 308 Redding Type S (actually, I still have it in a drawer somewhere) that I ended up replacing with a Whidden due to this issue. I already use Whiddens for my 300 PRC and 6 BRA.
 
Not necessarily, but I'd like to go down a little further without creating a donut. do you use this same die and "nut spacer" setup?
I have been using the SAC on for all my cartridges and so far after 7 reloads I never had any donut on any of my brass. I have been using 331 bushing following by the 306 mandrel with excellent results.

Well I'm glad someone agrees with me. It's been chapping my ass from the get go. The only reason I haven't addressed it is the rig runs my loads very well. I have a new pipe on order and id like to get this bushing BS sorted out. I reached out on here hoping someone made their own machined spacer. If not, guess I'll reach out to Whidden.

I tried whidden and returned it immediately
It was giving me super consistent shoulder bump but wasn’t sizing the base enough for my liking so I ended up with SAC.

Thanks, I was hoping to find a fellow member that had a work-around so I wouldn't have to change dies and all my titanium bushings.
For such a solid company, Redding sure screwed the pooch on this one.
 
Monos..has anyone gotten solids/monos to shoot?

Still haven’t found a load/mono combination that shoots tight groups in close

All seem to hover around .7 or so
