I run H870 which unfortunately ISN'T available any more . 160 Gr. bullet with 79.0-80 gr. US 869 is as close a performer in surplus canister grade powder you're gonna get .
VV N560 is very very repeatable accuracy wise and near full loads with 160.0 Nosler Accubond at 68.4 gr. puts Me slightly over 3K fps.
If you run 168's I'd run N560 65.4 gr. is what I load . " IF " You run 175 gr. bullet drop last recipe 1.0 gr. and you're near Max load .
I'd try and stay within 0.5 gr. less of those charges ,so You can see accuracy potential but would advise against going any higher in charge weight .
Unfortunately for the vast majority of you ,I have many obsolete powders which I still use and relating that info is useless too you.
Like Winchester Magnum Rifle Powder , a Double base Ball powder ,which I believe they discontinued due to dumbshits attempting to fill compress magnum loads with it . I read something way way back about people NOT adhering to stated recipes and disaster occurring ,so OFF the market .
I use it occasionally for Magnum Rifle loads ,even used it in .338 LM and Pistol powder but it's Powerful shit .
*** Brand New - Just Released *** First shots with the brand new ThunderBeast Magnus-S HUB (7") .30 caliber suppressor. Running it on my 20" Christensen Arms Ridgeline FFT 7mm-08 Rem. This will be my new hunting suppressor once I get my stamp back.
New video is up comparing the BRAND NEW ThunderBeast Magnus-S HUB with the full-size Magnus HUB suppressor.
I am packing 7mm RM and want second opinion. It`s been a while since I reloaded.
Rifle: Browning A-Bolt 26"
Bullet: Sierra Spitzer BT 160 GR
Powder: H4831. (start with 59.5 go up to 61gr in 0.5 increments)
Primer: Either CCI 250 or Federal 215. Need an advise.
Crimp vs No Crim? (medium crimp)
Also. How long can primers be stored in original cardboard package in ziplock bag? Is 8 years ok? I live in humid climate. Same goes for powder. Stored in original container. Should I remove moisture by warming them up in a microwave?

should be gtg on primers as they are dry paste compared to powder that's porous. as far as crimp or not goes, i crimp all regardless of semi-auto or bolt............just my preference as it works for me. just like turning necks, bumping shoulders or neck sizes it need to be consistent
I still use primers with great success that are >15 years old. How you store them is extremely important. Mine are stored inside my temperature controlled house in 40mm ammo cans. Humidity sucks here in SE Oklahoma pretty frequently, but if you can keep the storage area dry it will certainly help. NO WAY would I put one in the microwave...but if you'll do it and upload a video, I'll be happy to watch
.I wouldn't crimp my ammunition for any standard bolt gun. Maybe if you were shooting an African-game cartridge in a light rifle. My 7mm RM and 300WM have never needed a round crimped.
Either The CCI 250 or Fed 215 is fine. The CCI does have a harder cup for sure, so if you were trying to live on the uppermost limits of pressure, I'd go that route. I have a Bergara Premier in 7mm RM that will NOT reliably pop CCI 250s...yet has ~400 flawless rounds through it with the Fed 215s. My guess is that the .047 firing pin protrusion is just a tad too short in this one. Those same 250s that won't pop in my 7RM are 100% in my 300WM and my buddies 300NM.

primers do not burst in the microwave.
I had no idea. I thought I was joking. but I guess jokes on me
you are correct about the humidity sucks in se ok as i've tried a summer in ada and last year my son had a football game in seminole...........yup, a tx team played an ok team in early augustI still use primers with great success that are >15 years old.

Primers last for decades if simply stored in original containers and kept dry . Humidity doesn't effect them as it does powder .
More powder one uses from a larger container ( 8 lb. ) the more air inside the container . Ideally Powder should be kept around 50-65% humidity as it's packaged and stored around those vary parameters .
Standard taper crimp is set into Rifle bullet seating Dies , not aware of any special crimping die and where is it gonna crimp into ? . Bullets for 7 RM generally don't have cannelure in them taper crimp is sufficient . Fyi : rolling a Cannelure distorts the bullet no matter who does them .
Powder
I dedicated a chest freezer and store mine inside now ,in original containers . Older powders I open the lid for a day or 3 no longer ,then lid them back up . When I need to load something ,I'll remove what I need putting powder into another container taking it to the loading room ,while capping original back up and leaving it in the freezer . Seems to be working very Well . As I have a fair amount of Bulk powder and transfer that into 1 lb. containers that I've saved over the years , especially when loading high volume such as 9mm 5.56X45 and 7.62X51 . Cold powder slides out of the powder measure into the charging anvil without static cling ,ditto while pouring it via funnel into powder measure .
Load 60.5 gr. H4831 and run a handful of Sierra's 160 Gr. see where it puts you . I have a # of 7 RM'S including a Browning A bolt stalker ,yet I run different powder now days .

depending on the type of crip, it doesn't distort any more than neck tension.............roll crimp with cannelure will distort, but lee factory crimp die done correctly doesn't even w/o cannelure.
Misunderstanding : Bullet distortion occurs when cannelure is made ,not reloading or crimping . It's simply a fact that can't be avoided ,according to manufactures themselves .
Well, I did not find what I wanted so maybe someday someone will see this. I just went to the Hornady website and they list 60gr of IMR 4350 behind a 162 gr bullet but it was not the ELD-M I am using in Hornady brass. Well, I had Federal and did rather well but now all I can get is once fired Remington. I tried to find the case capacity of ( Hornady vs Federal vs Remington) and it just does not seem to be available and then to throw more stuff into the equation it says you do not count the angles section or neck volume when figuring out the case capacity. Then to add more stuff in they are say the same powder load in each one of the cartridges could yield entirely different pressure making the 60 gr of IMR 4350 a hot load. I am just blown away by this stuff. What are we to believe? So to make things simple I guess I'll ask this. Has anyone loaded 60gr of IMR4350 into a Remington case using a 162 gr ELD-M and been successful.
60gr of IMR-4350 ought to be safe in a Remington case underneath a 162 ELD-M.
Hodgdon lists that as max, but states that their pressure was only a bit over 58K PSI.

Though the manuals are usually pretty conservative, there is usually no better way than starting low and working up. Also try using Gordons Reloading tool. Which is a free program. I use it with great results. I personally start my loads at what the books would be a 75% load and work my way up. I find it amazing how many accuracy nodes I find at slightly lower velocities.
I finally got a decent supply of fireformed 7-08 Ackley brass using some 7-08 Starline brass as a starting point.
Rifle is a built Solus with a x-Caliber 24 inch CF barrel in a Grayboe stock and a Arken SH-4J optic.
I wanted to test 150 Gr projectiles first starting with 150 Gr. Gamechangers. powder is Power Pro
2000MR Federal 215 primers 3 rounds each
45.5 GR
2971
2973
2978
46 GR. These shot well but had loose primers- Possibly a Starline issue?
3001
3011

All info same as above but with 150 Gr Hornady ELDX
