TTSX and crumpled cases
Ruined 3 out of 6 cases .264 lbc and then lubed bullets to fix. Anyone experience this with copper? Once I lubed them they seated fine. 100 grain TTSX. Probably just the case taper?
Need to purchase a puller to salvage what I can. Expensive lil pills.

Loaded 30 rounds of .300 Win Mag this morning and no sign of the problem your having. I don't recommend using any lube on the jacketed bullets or on the inside of the case neck. It sounds like another problem if you crushing the case when you seat the bullet. Is your die set back far enough to not engage the crimp ring inside of the die?

I've never encountered this before out of 22 die sets and lead projectiles. Maybe more of a chamfer to case mouth.

Another thing, are the cases trimmed to length? have these cases been shot a lot? mike the necks and find out how thick they are. If they are to thick you should turn them down. You need good neck tension to help start pressure but not that much. Yes chamfer them if they need it, if they are work hardened maybe anneal.

Yes chamfer and do not crimp. I have zero problem with my 264 doing this. I also use Hornady brass with my 257W and 338win mag and possibly others without problems.

How are you cleaning your cases - dry tumbling with corn or walnut media or ultrasonic?
Dry media cleaning leaves a thin film of dust on the cases and this seems to act like neck lube when seating copper bullets. |

Ya Walnut media. I believe a really aggressive chamfer is doing the trick. I've never had this happen before out of thirty plus years reloading that wasn't something obvious.

Yes Barns TTSX 165 gr BT in my Rem. 700 .300 Win Mag. my rifle is set up for elk and deer hunting. I decided on 72 gr. of IMR 4831 with a Fed. GM 215 M primer bullets seated at 3.330 if I remember correct. Works well enough in my rifle but you might want to work it up to this for yours. My load is out of the Barns reloading book. I have yet to run this over the chrony and see what it is really doing but I zeroed this load in my rifle 2 1/2 inches high at 100 yards, should kill a elk out to 100 yards or so. I have 2 elk tags this year and one deer tag so maybe we will get to see this load in action if I don't have my 30-30 or something else in my hand when I jump a cow in the timber or tall sage/willows. Good luck working up your load for me it's always more fun to work loads than pack meat. By the way my .300 is primarily a open country rifle, I hunt other stuff with lots of other rifles timber, willows and tall thick sagebrush is the most fun for me so that's what I do most of the time. Short range shots are what I make most of the time 50,60 or 100 yards is where I kill most game. I'm rambling.

I use 168 TTSX for my 300 WinMag. CCI Mag primers and 71.6g of RL17 puts them at 3200fps out of my X-Bolt. Very accurate. Looking at my dope card now, I'm 1" high at 100, 0" at 150, 8.5" low at 300 yards. I took an elk just a couple weeks ago at 365 yards, lights out mid-step with a pass through. The Kudu was around 250 yards and same thing, dropped like a rock.
It's hard on the brass, but harder on the animals. Recoil is no worse than any other 300WM load. I'm so happy with the load over the last 2 years, I'm likely going to have a scope with custom turrets made for it. I've taken everything from jackrabbits to Kudu, big boar, and Roosevelt elk with it, and not a single critter has gone more than 20 yards. Most dropped in their tracks. |
