I'm only walking it because i'm working out the best seating depth, once i find that depth the seater will stay there for a while, till i play with new bullets. i'll have to play around with the annealing part. Do you chuck the bullet in a drill to get even heat?
Okay I ran a test with 6 separate pieces of winchester brass twice fired (not annealed, don't own one, i know theres some water method), all run through FL Forster die, trimmed to length if needed, inside/outside neck chamfer then cleaned with rotary tmbler and dried.
I then ran tests with just...
how did the 300wsm 18" work out? what are muzzle velocities, powder and bullet details?
how is the 7SAUM going? what muzzle velocities are you getting at 20", powder and bullet details?
Hey, guess i'm joining the club. I too bought a tikka t3x lite in 7mmRM. I'm planning to get a 18-20" proof barrel with carbon fiber stock and just got my thunderbeast 7" suppressor. I wanted 18-20 so that the overall length only increases 1-3 inches. I figure if I get an accurate load, i...
I run them through the factory forster full length sizing die, then run a .283 mandrel through the neck. I've been thinking of buying a SAC mandrel set for .284 and playing with different neck tensions, maybe i'll give that a go.
I didn't. Should I measure from the end to the tip, end to the...
I'm loading with winchester brass for my 7mm RM. i'm guessing the brass is pretty poor compared to lapua ect. So is my problem the brass, or technique/equipment?
After bumping shoulder back .002" then trimming, brush neck, inside chamfer, outside chamfer, brush neck again I use dry neck lube...
Cool. I haven't shot a 7rem mag in 20 years, but I remember it wasn't "that bad". Can't wait to shoot my t3x 7rem mag on ammo or reloading parts become more available.
Ubless they're guys that are long range hunting that want the higher BC and higher weight bullet that don't mind the recoil.
I do agree there's a ton of 130-150 grain factory loads now, but not nearly as many in the 165-175 camp.
i just watched this video, I wasn't amazing in physics in high school, but it sounds like everything in this video is plausibly correct. Quite fascinating,
double check that you can't over rotate lower grain bullets. I would assume there is a sweet spot, otherwise wouldn't all barrels be like 6twist barrels? There HAS to be some downside to having a faster twist barrel than you need.
If you don't hand load, i don't think you'll find anything for 270wsm that needs a 7, or 8 twist in factory loads, and you can't shoot the 6.8w out of your 270wsm as is,
but I believe you could rebarrel and have a 6.8w chamber cut into that new barrel and then you would have a 6.8w that would...
Glad somebody agrees with my thinking on this. I recently bought a 7RM due to the reasons you mentioned.
How light? pretty sure you can take any of the 270wsm bullets and load them. The 6.8w cartridge is only marginally shorter.
so i should probably be looking at if 4000-MR is a faster burning powder and if I can slowly and safely go up in charge grain if at 62gr its only at 87% capacity. I care more about my life and accuracy than max velocity.
I know chopping the barrel will reduce muzzle velocity, but does that shift the nodes, require you to find completely new nodes, or does the same grains of powder yield another node, but just at that lower velocity?
My guess is that you need to re-establish a new node because of barrel...
