Range Report Best .223 load for a 20 inch bbl

Re: Best .223 load for a 20 inch bbl

Sierra 69 MK with IMR8208XBR. 2900fps is pretty easy. Lapua brass, Wolf primers. Working with AA2520, 100yd accuracy is good, have not shot at distance yet.

23.8gr of I-4064 gave .4's in my factory barreled Savage this weekend with the 75 Amax. First time shooting them, no chrony data, but it should be around 2800fps from the listed data.

Amax seem to like a jump around 10 thou from all the calibers I've shot them from, this was no different.

For you guys loading the 73 gr Berger VLD's, what COAL do you use? How much powder are you loading, and what kind of velocities are you getting?

Thanks!
 
Re: Best .223 load for a 20 inch bbl

I have used this load in 2 AR-15s and it works real well. Sub MOA in both. Both have 8" twist barrels.

77gr SMK
23.1 grains H4895
CCI standard primer

This gives around 2800fps in both rifles. Play around with the seating depth and you should be able to get sub MOA groups pretty easy.

The BC for the 77grain SMK is much better than what is listed in most manuals. If you plug in .410 BC (G1) you will be very close.

By the way I am selling one of these uppers.

Thanks, Dirk
 
Re: Best .223 load for a 20 inch bbl

My Savage likes the 69 SMK's...its probably me but i just havent found that special load with the Amax's that really work comparable to the SMK's, I am also using Varget and CCI primers.
