LR load for M1a

[JBS]

Note: In my experience, the 2200 - 2400fps loads with 155gr bullets don't work all that well. With the light bullets, not enough pressure is generated to seal the case in the chamber. Sooty necks and less than stellar accuracy. If you want to run them slow, you are much better served with the 168gr bullets. Just MHO.

Caused by wrong powder choice.

Nope, not at all. Perfectly suitable powder was used. There is a reason why lightweight .30 caliber bullets were not used for 300 meter and International loads. Both M72 and M118 reduced velocity loads used 174 grain bullets.

300m isn't exactly "LR"...

It is when the Army uses 25 meter ranges for shooting.

I was referring to the chart showing 2200 - 2400fps loads for the 155gr bullets. Yes, you would not use such a load for LR, but such a load with the right bullet makes for a very accurate and light recoiling short range load. I use them for the 200 yard F Class Matches I shoot.

And if you used a powder with the correct chamber impuls you would get a neck seal and not end up with blow by. It may not operate the gas system but it will not blow by. I always turned the gas system off. I did not get blow by with cast bullets in the M1A either.

Actually, I was looking at the title of this thread as started by duggaboy. Reduced/short range loads weren't what he was asking about.
