Re: Subsonic Load Development

There is no N105 data for 180gr + subs in Hornady 9th, Lymans 50th, VV 2019 manual, or VV website.

Re: 1/5 Twist and Supers

Anecdotal evidence, but my 7 inch Q barrel groups 125gr TNTs loaded with N110 for accuracy as good as my 9 and 10.5 inch, 1/7 barrels out to 200 yards. The Q barrel groups long, heavy subs slightly better than the other barrels. I've shot three different Q barrels with similar results. That being sa...

Re: 11 inch barrel and carbine gas

Ok, there's good news and, based upon how one feels, bad news getting subs to work in my barrel. Good news: I found a couple different combinations of powder weights and seating depths of subsonic loads using N120 that will consistently BHO on the last shot. Bad news: they only work with the 762SDN-...

Re: 11 inch barrel and carbine gas

Very acceptable results. I started by moving CBTO out .100 and worked back in .025 increments with the same 17gr charge of N110. From .075 to .100 out, I had BHO on every shot unsuppressed. No warning signs of pressure. At .050 increase and less, I ran into inconsistent BHO issues with Magpul 300blk...

Re: 11 inch barrel and carbine gas

I loaded up 4 strings of ten rounds at increased CBTO/lower case capacity with the Speer 125 TNT and N110. I am encouraged for sure. Off to the indoor range in about an hour. The getting the 125 SMK to work with my current charge of N110 will make me explore the importance of case capacity/construct...

Re: 11 inch barrel and carbine gas

As always Dellet, thanks for the perspective. And yes, at this point I feel opening the port is the easy way out. I'd like to try some load development first as I'm *this* close to making it work as is.

Make sure it's well broke in before you drill and don't forget that moving the bullet out on the sub loads can be very helpful.
Hmmmm. I've been seating the subs so that they are sitting right on the N120. With the N120, are you suggesting moving the base of the bullet away from the powder?

11 inch barrel and carbine gas

So, this is an idea I hatched back during lockdown in April. I own a 7, 9, and 12 inch barreled uppers with pistol gas in 300BLK. I wanted to try carbine length gas on a shorter barrel just to see if I could make it work for a rifle that would always wear a silencer. I pestered dellet in a couple PM...
