Hey all, I'm getting into reloading very shortly and was wondering what would be the best suited powder for loading .270 130gr SST's? I was also wondering if the Interlocks would be an all around better bullet for moose and deer. Thanks for any and all suggestions!

If you go to hodgdons website they have loads for the barnes bullets on their site. The sc or ssc designation means that the powder should burn more consistantly. 4831 looks like it produces as good of velocities as other powders, but the more modern ones might be more consistant.
 
Okay I was looking at Hodgdon's loading data, and from what i gather IMR7828 will give the most velocity while still keeping the pressures around the same as the IMR4831. So if that is the case, than why would I not go that route? Like I said I have zero experience in reloading, is there anything in particular I should be looking for in a powder or just follow the tables and try different combinations to find what shoots best in my rifle?
 
Might consider going with some 140 or even 150 grainers if you're going to use cheaper bullets. The 270 is no slouch with velocity and will be quite hard on the mentioned bullets at close range if you're targeting moose and may not penetrate well, I would suspect the 130 gr would floor a deer but the meat damage will be extensive if a shoulder is hit, that was my experience with 165 sst in a 30-06 on 2 deer a few years ago, the sst is known for being frangible at higher velocity. Often those non premium cup and core bullets perform better in a heavy for caliber weight. For powders get the hornady loading manual and use that as a general guide for powders. The interlock will probably open up a bit slower than the sst

RL 22. Use a better bullet than SST for moose. IMHO

X2 ! The 130 SST is NOT moose bullet. I personally find it too frangible for deer less than 300 yards away.

For mixed use for deer & moose the 140 grain Accubond loaded over Reloder 22 or H4831 would my suggested load for a .270
 
I agree, a better bullet would be in order for moose. I have shot a couple moose with a .277 150 grain partition and it did the job. They also make one in 140 grain, or the accubond would be a good option. I would look at any of the higher end bullets for moose hunting with the .270 myself.
 
I think I'm going to go with the Interlock at 130gr. From what I've read and others have stated, it is a tougher bullet than the SST. I don't want to go to the 150gr as this rifle is not my dedicated moose gun, I just want a bullet that is tough enough to handle moose if the opportunity presents itself. As far as the 150's, I've tried them in different factory loads and could not get better groups than 2.5 moa. Not good enough for me.
 
The 140 grain Accubond would be a great compromise.....or a Partition of the same weight........The 130 grain Barnes TSX will certainly do the job as well.....

I'm sure the SST is only a different looking interlock unless Hornady skimped on the packaging.

OP - Interlock/SST is probably a poor choice for moose especially considering that for several dollars more Hornady produces a fine 150gr Interbond bullet that costs more for a reason: More effort is spent constructing a bullet that retains more weight after expansion. There are plenty of GMX style bullets that because of being entirely copper, retain even more weight.

Here's a cross section of some Hornadys' & Noslers (not my pic, but helpful).

First two red-tipped rounds are SST & Interbond respectively. The second in from the left is an Interlock SP, while the remaining are Accubond, Ballistic Tips for comparison.

You can see why the SST is prone to fragmentation & not a good choice due to its' thin wall design.
