ttsx question?

[chain2]

hey fellahs, Im loading some [300wsm] 150gr. ttsx's over 64gr imr 4350 for the first time. They are such a long bullet they are *almost* compressing at min charge. I would think this is common as they are such a long design?? I would like to shake test to verify my hunt loads are charged...anyone use this combo or is a change in powder my answer? thx chain

I use WW760 or H414 in my son's .300WSM.

If you are really concerned, just put each loaded round on the scale. As far as the load is concerned, a hunting partner used the 168gr TTSX in his 300WSM this fall, and they shoot very well.

thx, I never contended with comp loads before and they're not right now...but close as Ive ever came... and this is at starting min load. Ill try it out. I have a max oal for my mag and choose imr 4350 after reading the net. chain

Have you checked the distance to your lands for that bullet ?
Being such a long bullet as you say, maybe you don't need to set it so deep to compress.

I pay no attention to the COL listed in the manual. It isn't for my rifle, so it is pretty much meaningless.

Start out seating the TTSX about .050" off of the lands, as long as the rounds will fit the magazine, and you have an adequate amount of bullet shank in the case neck.

I have it as long as my magazine will allow. I have no interest in single feeding
heres a nosler bt 150 vs 150 ttsx for comparison...BC for the bt is .435 vs ttsx .420 which I thought would be the reverse...so I guess I dont really understand this stuff afterall lol chain

So what exactly is the problem?

The grooves in the shank of the TTSX reduce the BC.

It sounds like there is no problem, other than the OP seeming concerned for no reason.

The one concern you will have with compressed loads is neck tension.
If the necks are not tight the projectile will not sit in a fixed position.

The first time I had a compressed load I was worried so I only did a few, if the charges are correct and you are following the recipe you should have no problem. After a few times of the crunching sound and nothing happens you should be good.

After you have poured the powder in the case, set the bullet on top the case mouth hold it there to keep all the powder in and give the case a few light taps with something like a pen, pencil or felt marker, or lightly tap the case on the side of the press a few times right before you put the round into the shell holder on the press. The powder will settle a surprising amount, turning your "almost" compressed load into what you are more used to. A long drop tube simialr to what many black powder shooters use can also be helpfull.

Orther than possibly some neck tension issues to hold the bullet in place, there really is no issue with running a compressed load. If you are worried about bullet creep, seat the bullet then place the loaded round on it's side and give it a roll. I have not been able to get enough powder in to get bullet creep, but I have never really tried either.

I have even known one person to set a case with a half seated bullet on a case vibrator for a few seconds to get the powder to settle before seating the bullet the rest of the way.

thx for the replies, Longbomber..there was some settling of powder as you mentioned. my problem was.. I wanted to just pull the nosler bt's I already have loaded and swap them with the ttsx's. but they are a full grain more than my *almost* test load which would compress them. I think Ill fire the test load over the chrono and just start some fresh cases...ill see how it shoots...thx again chain

''Swapping bullets'' never worked for me! I can remember a magazine and chamber full of H4831. Isn't neck tension lost when bullets are pulled?
