The silencerco person said that this can was rated for 300 wm with no problem but couldn't handle a supersonic 300 blk in a 10.5" barrel. What makes the 300 blk out so much harder on the can. I know the short barrel vs long but your burning 4 times the powder in the 300 wm

What are the pressures? That is the question you should be asking. Be willing to bet a standard barrel 300 win mag has less pressure than a 10" 5.56 or 300blk
New to suppressors, but pressure at 10 inches is much higher than pressure at 24 inches regardless of amount of powder. You can see the pressure curves here: Rifle Chamber Pressure Testing Software & Load Analyzer | Pressure Trace
Harvester min barrel length is 16".
There have been posts and pictures here about Silencerco people using Harvesters on 6.8 SBRs while hunting hogs, so while I'm sure it can "handle" short barrels, it isn't designed for them. As such, Silencerco won't warranty the Harvester if they are used on short barrels.

Here is the reply from Silencerco
Thank you for contacting us. All of our suppressors have a minimal POI shift when they are added to a rifle and the shift is repeatable. The Harvester would be great on your 260, 300WM, and 7 RM; the problem comes in with your 300blk and 556. The Harvester isn’t rated for use on barrels shorter than 16” with standard loads; you could use the Harvester on your 10.5” 300blk but the loads would need to be subsonic. If you are wanting a suppressor that will be able to work with all of the calibers and configuration that you mentioned I would suggest looking at the Saker 762 or the Specwar 762 these suppressors are rated for calibers from 22 Hornet up to 300RUM and are SBR and full-auto rated as well. Please let me know if there is anything else we can help you with.

Yes, that is what was said on the video, which should be plenty good for a precision rifle, possibly for a 16" semi auto fire(you would have to check with them) but not SBR. As grant said, for high pressure and short barrels, the specwar and Saker are quite good from what I read.
Extreme lightweight and high rates of fire do not mesh well. I have a Harvester for the bolt gun and it stacks right up there with the best available for that application. The Specwar is excellent for SBR use, and wont break the bank. Id go with a Specwar or AAC SR7 if you want a "do all" can.
So, how many people here on the site own a harvester and can assert that the accuracy is comparable to a TB?
