510 Whisper Build Advice (Stock/Bottom Metal/Magazines/Twist/Barrel Length)

The reamer drawing I have has the chamber at .539, so probably less than that. You'll probably have to figure out what works with your chamber/brass/dies.

I appreciate the suggestions 45-90! I would be ecstatic with 200 cases per hour, as right now I'd be lucky to do 10. I think my biggest mistake is trying to bottom out the mandrel and move the carriage to a stop rather than feeding it with the tailstock. I will probably just try using a reloading press shell plate mounted to the tailstock to make removing it while running easier for me.

Elk Hunting Rifles, What are you Using?

15#s with the bipod.
I had 15lbs before I edited it haha. I figured 13.5 with no can, but that must be a heavy barrel.

6.5cm from last year….14lb 12oz. Heavy enough that I’m building a 6.5prc that’s 4.5lbs lighter for my wife to shoot (because I have to carry it 😆)

Curiosity Test.. Brake VS No Brake and Expander VS No Expander

Wondering if running my brake had an effect on accuracy and also whether using a neck expander or not effected accuracy. My data set is very small, I understand that, but was wondering what the results might indicate... Results are 5 shots each at 100 yards.
Equipment:
Tac Ops XRAY-51 .308, ZCO 5-27 scope, Alpha brass, Berger 115 flat base target bullet, CCI small rifle primer, VV N-135, 44.0gr. 2.190 ogive, @3025 fps. SAC modular sizing die, 334 bushing, 80 degrees, overcast, no wind.
Results:
Left side is no neck expander with 4 port Hawkins brake and with no brake.
Right side is using a 306 neck expander with the same brake and then with no brake.....

Assuming all things being equal... Not using the neck expander with No Brake appears to be the way to go. At least with my equipment. 5 shots measuring 0.097".
Tiny data set, but interesting to me.

Zogbots brings in APC and murder man over tall grass bylaw

I never mow during a heat wave.....or a cool spell. Fight me code enforcement.

I do know a lady who went ape shit on code enforcement trying to make her cut her sunflowers. It's been years since they have said anything to me. I was just chopping 6 ft wild lettuce off the ally side of my grape vines. Anything I don't want to mow now is a crop, a cover crop, a trap crop, a compost crop, or an ornamental. 🤣🤣

Maybe there just ain't no narcs in my hood.

P=Personal, are as many as there are individuals who fired them across AB's mobile lab setup. While it can provide some interesting info they are only meant to be used by the individual who fired it.

The CDM are the ones to use.
Cheers!

That makes more sense, I found the correct one now.

Bottom Metal for Coup de Grace Build

I just put one on my last rifle and can’t believe much difference it makes.
In what way?

Also, I just got off the phone with someone at Hawkins who cited all kinds of fitment issues with the CDG receiver. Surprises me because ARC recommends their bottom metal. 🤷 I did see a recent thread about problems feeding 7mm-08 specifically in their proprietary Hunter magazines.

screw worms arent a problem in the US, yet. they last were in the 60s. its impact is that we are being careful with Mexican cattle, which i think has been stopped all together.

the higher prices are going be in the lack of supply because the Texas cattle producers (largest cattle producing state) have had to sell more of their breeding herds because of drought. we are all currently trying to rebuild our herds and its going to take a couple of years, but there are very few who are going to be borrowing money to buy replacement cattle at historically high prices. we are all going to breed for them and not sell.

case in point, i have two heifers out of my calves i am going to trade with a buddy of mine so we can get them away from breeding back to their daddy bull.

the biggest driver of price increases have been reduced herds because of the droughts we have been in. we need more rain and that will help prices stay flat for a while. but i dont think thats going to happen until we fix the low herd numbers.
Correct. I don’t buy cattle on loan but I know several who still do. It’s the lack of headcount in the US herds that’s the problem. The tariffs and the screw worm issue are exacerbating the shortage.

This last drought and fires in Texas had absolutely beautiful heifers going to slaughter. That was tough for everyone and it’s going to take time to get us back to carrying capacity.
