Ive decided (after resisting for some time) that I will leave the 180 realm for a bit. Ive gifted myself a box of 168 Tipped triple shocks from Barnes. I know there's a lot of folks who love these things, I have IMR 4064(4 lbs) and would like to see if anyone has some pointers with these different bullets. I would really like to get as close to 3000 fps as I could, 4064 has been really generous to me with pressure in the past.

I would be one of those who "loves those things" . A few points as to the TSX series bullets to bear in mind are ,,,, They run long in length for their weight, they tend to like higher than average set back from the lands . This can be a blessing or a curse. If you try using powder that runs more than 90% full case volume at near max load data you get compressed loads and some powders get a bit touchy here . Another point to ponder is with the ring and groove style bullet shank tends to help reduce pressures slightly as there is less load bearing surface of the bullet contacting the barrel and therefore less drag. When Barnes first progated this style bullet they were well aware of this and not having published load data for this bullet for nearly 2 years their advice was due to decreased pressures you could add 1 or 2 full grains of powder to the old X bullet data . As old X bullet users found the X bullet was made of poor gliding metal and pressures ran high for their weight and they were mofos' for fouling bores. Roughly translated you could add 2 grains easily of powder to load data from the top reloading manuals and in many cases get top speeds as well as accuracy out of these bullets . My top 2 powders for the 30 cals with the 168 gr TSX Match bullet are IMR 4064 and IMR 4350 . As always work your loads up slowly and watch for pressure signs . I did making sure not to leave anything to chance by measuring each of my cases prior to and directly after firing with digital calipers and checked them with a good quality magnifying glass . I have had great success with the TSX and find them unmatched for terminal performance . Hope you find the same.
Using both 7mm and 30 cal in WSMs. Terminal performance is outstanding, with one exception- a 120 gr tsx apparently blew up on short range white tail???? not supposed to happen. Meat loss can be considerable, but not limited to TSX. Accuracy wil vary rifle to rifle. Mine seem to like the bullets for most part. For reference the real difference between the 300 WSM and the 30-06 is about a 100 yds. Nothing really special there.

Here's part of what's on the site:
30-06 Springfield
Bullet Weight: 168 gr ... Case Trim Length: 2.484" ... S.D. 0.253
Bullet Style: TSX BT ... Primer: Federal 210 ... B.C. 0.404
COAL: 3.218" ... Barrel Length: 24"
Case: Winchester ... Twist Rate: 1:10"
IMR 4064 ... 46.5gr 2594 fps -- 50.0gr 2801 -- 95% load density
Big Game ... 50.5gr 2648 fps -- 55.5gr 2869 fps -- 98% load density
If anyone has any 30 cal 168gr Barnes Tipped TSX's lying around (or if you know off the top of your head), could you please tell me the overall length of the projectile?
I am trying to work out the ideal rate of twist for these projectiles fired from a .300 WSM... My gunsmith said that 1:10 may be a tad fast for a lighter weight bullet, however as the Barnes TTSX appear a tad longer than other 168 grainers... maybe the 1:10 would suit... Any thoughts or advice?
Cheers
