130Grain TTSX

I'm new to reloading and think that I have the entire set up required.

My first 'kick at the can' will be 130grain Barnes TTSX for a .270.

I've been reading (and downloading) lots of information off the net with respect to procedures and what not. I downloaded Barnes's spec sheet off their website and it shows a COAL of 3.300". When I set up my press to seat the lead I still can see the upper most band.

Is this normal? or should I seat the bullet lower so I can not see any of the bands. I've read somewhere that it should be 0.050" off the band(s).

Thanks for the help

Have you ever made up a "dummy cartridge" to check how long you can hang the bullet out?? To do so take a fired case and size the mouth enough that you can seat a bullet with your fingers but it has some friction. Hang the bullet out a long ways and chamber it and close the bolt gently. Then carefully withdraw the cartridge and measure the length..it should be very close to your max overall length. Hopefully the bolt has pushed the bullet to the rifling and not much further as you closed the bolt. You should probably deduct about .010" from the length you got as the bullet probably went into the rifling slightly.
You should take several measurements and make sure they repeat themselves as sometimes the bullet sticks a bit when you withdraw it. With some practice you will get a feel for just how much friction there should be and you will get more confident in what you are doing.

Actually, it's 0.050 off the lands.

Oops...I forgot: The relief grooves do not have to be in the case and non-visible. It is perfectly fine for them to show and has no detrimental affect on anything.

One of my 270s likes 55.5gr H4350 and this same bullet. It does not matter if any of the relief grooves are visible after you seat the bullet.

You need to buy a gauge that tells you how far out a bullet can be seated in YOUR rifle to start seating them properly off the Lands.
