I’m loading up some Barnes 110 gr over some H110 today. They’ll be shot out of a 10.5” 300bo suppressed. I’ll be using it for deer this fall. Does anyone have a starting load for me? Is this something that needs to be pushed fast? Lyman has the max at 19.5 compressed.

Reduce by 10% and use that as your starting load.
Barnes uses H110 for their commercial loads. It doesn’t need to be a screaming load.

Thanks for the reply. I wasn’t sure if the reduced barrel length will hurt the expansion. I doubt I’ll get over 2300 with a 10.5Quote:

When in doubt shoot some wet news paper

Barnes' load data here: https://www.barnesbullets.com/wp-con...utV6ForWeb.pdf
Starting is 18.2, max is 20.2
I shoot this bullet out of two of my 300BLK's. A single and bolt gun. Same load for both. 20.0grs of H110 will give me 2380fps from the 16" 1:7 twist bbls. I use a flea market electric tooth brush,held against the brass with powder to viberate it down to a barely compressed load. This bullet (30321) will expand adaquately down to 1300fps. I have killed hogs up to 265lbs with this bullet. --- SAWMAN
The suppressor also acts as barrel lengthQuote:

I’m not sure that’s how it works.Quote:

I use 20.0gr of H110 out of a 16” bolt gun with that bullet. I haven’t chrographed it, but is is extremely accurate. Killed multiple hogs and deer with that load.

I have heard of this phenomenon. I’ve heard that a barrel with a suppressor will get higher velocity than the same barrel without a suppressor. Not only has it been told to me, but I remember reading it somewhere, just don’t remember where.Quote:

Basic physics - - -> Increase volume,decrease velocity. The bullet is being pushed down the barrel by the increased pressure behind it. The volume increases when the bullet enters the surpressor,the pressure decreases,bullet speed goes down.
Have I got this wrong ?? ---- SAWMAN
Suppressors do not have room for all the gas sent to it so the left over gas after full capacity is still pushing the bullet. Now sub loads have way less gas so this theory may apply to them, but super loads not so much. One the second shot some claim the gas holds up in the can so it is already full. I can’t testify to that theory but I know what my YHM does to my loads
