Powders for semiauto rifles

[Rat44]

Decided to use my inherited Bar Mk II in 30/06 this year exclusively .
I have been loading for my Rem 700 since the 80's using 3031 and 4064.
Using 125 and 180 gr bullets .
Are these powders compatible with the auto loading action or will I have issues.
Shot some Fed Premium 180 gr Noslers and Barnes 180 TSX last year and they both functioned ok .
New to loading for autos and I have heard of pressure issues.
Don't want to cause my self problems if I can help it.
And yes,I will be using small base dies.

I didn't see what bullet weight you were wanting to use, but I've did a lot of reloading for the 308 and 36 semi automatics using various 150 to 165 grain Bullets.. When loading for the 308 I had great results using 4895 Hodgdon and with the 30-06 in the older Remington 740s and 742s 4895 may the action cycle more reliably however when the 7400s and 74s came out in the 30 odd six I found they likedH-4350 better.... Several of my family members had variations of these Remington auto loaders and I did the reloading for everyone usually 200 to 300 rounds per year for six different rifles.... When using the Reloading manuals, there are multitudes of powder that will work in bolt rifles that will not work in auto loaders because of the action malfunctioning.... Back in the 60s when everyone was still alive and using many rounds per year in the woods, I would chill the ammo in the refrigerator during the summer and do the load testing because some of the loads worked when it was warm would not cycle the action when it was cold during deer season so keep that in mind if you're going to someplace like Alaska the ball powders were the worst of all so I would be aware of those..... I've also reloaded various rounds for the A.R. 15 rattle guns and they seem to burn and shoot reliably with just about anything you can dump in them, which is much different than what I found that worked in civilian hunting rifles.... So I guess my advice is try the loads in cold weather or chill them before testing to a temperature that you would find on the typical hunting day and now 50+ years later with the 308 and 30-06 using modern powders reloader 15 works best of all and no matter what Powder or caliber, I always used Magnum, primers..... I hope this advice helps you for your cold weather hunting loads....Roger

oooppsss ,,,,I forgot to say anything about the dies......... I highly recommend using a small base die of the appropriate caliber for any auto loader

A2495, A2460, Tac, H335, H4895, Varget, have all worked well from my FAL, Zastava M77, My M1A I don't use TAC, or Varget, due to the pressure curve on the op rod, That's just me YMMV!

A Browning BAR can be treated like a bolt action, AR10s and 15s can be more temperamental depending on the length of the gas system, barrel length, and buffer weight, and can somewhat be controlled with an adjustable gas block. Most BARs are slightly under gassed, and take high pressure bolt action loads to function properly.

Good to know.
Just didn't want to create issues that could be avoided.
