First off, I am aware that all rifles perform differently with different kinds of powders, primers etc. I am just trying to shortcut the process a little bit and find an accurate load. What do the rest of you use for accuracy?

I have loaded my Remington 700 ADL rifle with both Reloader 19 at 47 grains and 50 grains over 130 gr. Remington Core-Lokt bullets with a WLP Primer in a Winchester case. I just got a pound of IMR-4064 to try. I read that a good load to use for accuracy is 43.5 grains of 4064.

This is my first shot at loading rifle. I have done quite a bit with handgun and shotgun. Any recommendations for powder etc would be greatly appreciated. Thanks.

I`m happy with a 130 gr Hornady BTSP over a stiff charge of R22 with a WLR primer in mine. H4831 has been called the powder of choice for the 270 and you wont go wrong useing it either.

My first choice in trying out a .270 for accuracy involves IMR4350 and 130gr Hornady or Sierra BTSP. I've seen too many that will shoot sub-moa out-of-the box with this powder bullet combo to look anywhere else. You can also add the 130gr Nosler B.T. to this list.

Try these; they aren't max, but are near max and are factory velocity duplication, which is usually near rifles capability in the .270wcf. Unusual for a 70+yr old cartridge. Al three will give about 3,000fps from a 22"bbl, and near 3,100fps from a 24"bbl.

54.0gr IMR-4350
54.0gr H414
58.0gr H4831 or RL22
Your primer, or case of choice, just use all of ONE kind, don't mix/match.
CCI, Win, Fed, NON-Magnum have all given similar results. Difference is usally less than shot to shot variation. Just be sure to use all one lot of brass. Trim to 0.10" under max, and size without pushing the shoulder of the case back (avoid total case sizing).

If one of these dosen't work, find another rifle !!!

I have had trouble getting my cases to securely hold the bullets with any crimp after I neck sized the cases with a Lee collet sizing die.

1) I neck sized the cases.
2) Trimmed and deburred the cases.
3) Primed the cases.
4) Charged the case.
5) I then seated the bullets with a strong crimp (crimping die almost touching the shell holder) in the crimping groove to 3.24 inches OAL.

At this point the bullet was loose enough to be turned by hand in the case etc. I set them aside and adjusted to slight/no crimp with the same results. At this point I had thought that the heavy crimp might have fractured the bullet copper casing etc.

I then backstepped and full length sized the cases and redid all the same steps with light crimp this time. The bullets stayed in the case fine this time.

Any thoughts or suggestions? Thanks.

first why are you crimping the cartridge? Is it being used in a auto or punp rifle.
If using a bolt action or single shot rifle crimp may not be needed.
sounds like the die may not have been adjusted correctly for neck sizing. I use a die specificly made to neck size cases rather than adjust a full length die to do the same,if you use the FL die to neck size blacken the neck with a magic marker then bring the die down til you're about 1/16" above the shoulder but if this is hunting ammo full length size to avoid problems in the field.
cimping is used in auto,lever and pump action rifles to keep the bullet from being pushed into the case during loading or pistol bullets to keep them from being pulled from a case during recoil,also TOO much crimp can distort the bullet affecting accuracy. Heavy recoiling cartridges ie 458 Win and the like should be crimped
If you can pull out the expander ball and measure it with a set of micrometers,
the expander should be .001 to.002" smaller than bullet dia.
hope this helps good luck

The rifle is a bolt action, I do not have to crimp but I do like to have light/moderate crimp. I am just concerned about bullet setback, whether it is from loading and unloaded the rifle magazine or just handling the cartridge a few times etc.

I was using a Lee die specifically made for neck resizing.

I use 47 grains of 4064 behind all 130 bullets.In my mod70 when I put that behind a 130 Nosler ballistic tip I get inch and a half groups at 200 yards.

I just finished loading the 130 grain bullets with 43.5, 44.5, and 46.5 grains of IMR 4064 powder. I will try them this weekend.

Dont overlook h-4895.

I use it and 4831 both. The 4895 is a faster burning powder, and has a little shrper recoil.

It seems to work quite well with nosler BTs.

Likewise. I also choose IMR4350 for 7mag 140 grain and 30-06 150 grain loads to get top velocitys and sub moa groups. Do not crimp for your bolt gun!!
