Ok so serious discussion time: who has user data on the new .300 PRC, it is looking like a contender for the win mag throne but my in depth ballistic knowledge is lackin

When did it come out? I haven't heard of it yet

They put it put a few weeks ago

Before the new factory

I'm a shameless hornady fag and also rcbs

Oh I like hornady fine, problem is stuff like that only catches on if the manufacturers start putting out rifles at accessible prices, otherwise it goes the way of 6mm creedmoor or any of the countless AR platform 5.56 replacements that arnt 300 aac (or 6.8 to an extent) and becomes harder to find, and higher priced

I mean look at 6.5 creed

.300blk

Most calibers that aren't in military service drop off after a while

Although there has been some new interest in a 6.8 rifle which I'm not opposed to

6.5 and 300 look like they are doing fine for what they are from what I see, I haven't seen heads or tails of .224 valk all year though

What does seating a projectile more shallowly in the Cartridge do anyway?

More powder

.224 valk is starting to show up more

I thought it was an accuracy thing

I've not even had anyone ask if we have it so idk

I mean if you move a projectile up even 5 thou it does affect your accuracy

Most guns have the bullet 15 thou from the lands of the barrel and the closer you get to the lands the more accurate, but then you run into heat issues when it gets super hot

Your stock factory 700 will have it 15 thou

Just because the projectile starts out seated in the rifling?

Or atleast closer to it

My IRL bro thinks the forward assist is a good thing

How do I tell him he’s stupid@

not stupid just old

a forward assist is like retard proofing a rifle

I mean is there a problem the forward assist solves

If your round doesn’t chamber right the last thing you should do is hit it really hard

Anyone who thinks a forward assist is necessary is either old or a marine

Minecraft gun 😎

Epic

Man this channel is gonna be a shit show in no time

What tool is used to cut rifling? And what do I need to use one?

a lathe i imagine

A big ass lathe

You'll need a broach

Well broach isn't right. A reamer for your maximum thread ID and then something to cut the threads

5r better if you want to put the work into it

I doubt it's a lathe

Not a normal one

define normal

you know what

get a drill press and try it

It will run on a normal lathe

Its gonna blow chunks and your gonna be hanging off the end but it will run

Even then that still doesn't answer the question of what kind of cutter it is

I recrowned a mosin can I post in here?

I forget the tool name

GTS nigga

Rifling is traditionally cut by a special gun drilling machine. Its a single purpose machine that pushes a very hard button through the barrel repeatedly. Sometimes 1 machine is several spindles together. They are liquid cooled.

Here is the cutting edge and base. You can see the holes for the coolant.

You just push the carbide through and the lubricant keeps it from setting itself on fire & floats the chips out

Home rifling to commercial quality is not possible. You can produce "rifling" with some screw jigs. Remember it's two steps. 1. Drill barrel from bar stock 2. Cut grooves with high pressure carbide button

I never got into rifling

Just buy a kreiger, proof, or bartlen

Get it hand lapped

You can cut some not terrible rifling if you have a smooth barrel blank that is reamed correctly already & a hydraulic press

You will need a button like this

You got the print for a 5r button?

Just get a catalog from whatever tool supplier is willing to sell to you

I'm pretty sure 5r can be cut with a button rather than an expensive broach. As long as the twist rate is the same inside

Weird looking rifling I tell you hwat. First i've seen it

5r?

It's so much better than standard imo

It applies better pressure on the bullet and equalizes the spin

I worked making coonans for half a year, anyone familiar with them?

Was rimlock ever a big issue?

Depends on the gun

Enfields, with proper ammo? Almost never

Mannlicher rifles had the en-blocks to stop it from happening, and nuggets

Well

They’re nuggets

@Alpharius I know coonan fal receivers are currently the big gay

Fuck off Reich we talking bout Coonans

^

And enfields rimlock like a motherfucker don't try to tell me otherwise

Sorry I didn’t catch the Coonan part

And I’ll tell you you’re a fucking moron

Original mark 7 and 8 ball, and all the stuff before and after pretty much never rimlocks

And anything with correctly made cases is fine too

It’s modern hunting loads that cause problems

It’s like using modern 30-06 in a Garand, just less severe:
Use correct ammo and there’s no problem

Rimlock is inherent to a box magazine fed rifle using a Rimfire Cartridge, how does older ammo change the issue, is the rim less square?

The Garand's issue isn't feeding due to Cartridge shape it's pressure, that doesn't make any sense as a comparison

How, mechanically, does "correct" 303 solve rimlock

the rim is beveled so that rounds slide over each other when inserted, and the internal geometry of the magazine is set up to allow and encourage this

Ok, so it IS less square

That makes sense

Correct use of stripper clips with proper ammo = no rimlock

Yeah, I haven't done anything with any surp 303, just modern FMJs, so that makes sense

The beveling might also help with the cartridges slipping over each other on me as I load the clip
