Thread: Crimping ttsx's

Hey mate

I load 150gr ttsx in my 7mmRM, I use a taper crimp to hold them in place and they don't move under recoil, advantage of this is you don't need a cannelure to crimp them.

Bear in mind that I had always intended them as a hunting load so they were developed from word go with a crimp, crimping an already developed load will change the pressures slightly so you probably will have to do some more development if you go this route.

Good luck!

Have loaded thousands of rounds in a number of different calibres and rifles, never crimped one yet, including in heavy recoil rifles, not a fan of crimping.

My previous post, I was refering to TTSX bullets,

-2506 Rem, 100gn TTSX@3400
-.257 Wby, 100gn TTSX@3600
-270 Win, 110gn TTSX@3300
-270 Win, 130gn TTSX@3100
-270 WSM, 110gn TTSX@3400
-270 WSM, 130gn TTSX@3200
-7mm Rem Mag, 120gn TTSX@3500
-7mm Rem Mag, 140gn TTSX@3250
-308 Win, 110gn TTSX@3100
-308 Win, 130gn TTSX@3100
-300 Wby, 130gn TTSX@3600
-300 Wby, 150gn TTSX@3400

Some of those are stiff recoiling loads, none of the above have ever been crimped, the .30 cals don't get much neck unless you want huge jump, especially the factory Wby. The problem is either an anomaly in your box of projectiles (which would affect thousands of others using the same batch) or a problem with your dies/technique. Never loaded the mid range or heavy for calibre Barnes myself, seems completely pointless given how the Barnes are designed to kill, would be interested to learn the cartridge being loaded and the seating depth/OAL
