Light bullets and bolt weight.

Trying to get the Trecenti to work better with less expensive 190 gr. bullets while remaining subsonic. Spent the morning doing some experiments. Tried out a 1.5 oz lighter bolt with no other changes. Yes, it does make a difference. The issue has been last round bolt lock. The bolt already locked ba...

Re: New! The S.I.A. "Trecenti" 300 BLK integral suppressor

I'm about to go out and try a slightly lightened bolt. The "Best" load I have on hand works great except that it does not lock the bolt back on the last round. No big deal for some folk, unacceptable to others. I have another load that does lock the bolt but it's transonic and you can clea...

Re: New! The S.I.A. "Trecenti" 300 BLK integral suppressor

Not quite, the lands and grooves for .30 are very close together to keep the ports between the lands. I also felt that there really is not enough barrel length after the gas port without losing the residual pressure needed to operate the action. So I port into a short extension added at the end of t...

Re: New! The S.I.A. "Trecenti" 300 BLK integral suppressor

Six baffles equally spaced. Spacers are integral to the baffle. I have found that putting more baffles too close together is less effective. So fewer actually work better as the gas gets a chance to expand between baffles. Nothing spectacular. Keeping cost down and serviceability up. Pic from my sit...

Re: New! The S.I.A. "Trecenti" 300 BLK integral suppressor

Current host lower is exceptionally heavy due to an adjustable target stock, Will get weight once I put a standard lower back on. So far no one has found the weight or balance objectionable. I am in Gardnerville, fifty miles south of Reno, fifteen miles east of Lake Tahoe. Only fifteen miles from th...

Re: New! The S.I.A. "Trecenti" 300 BLK integral suppressor

OK, I'm interested. If this can just uses step-cone baffles, what design features make it so much quieter than others? Your comments make it sound like this is about as quiet as a suppressed 10/22 with subsonics, but I've never heard a suppressed 300 Blk (semi-auto) that's anywhere near that quiet,...

Have not had that opportunity as I do not know anyone who owns one.

Everyone who has handled the Trecenti has been impressed with the performance.
Will try to get it metered ASAP.

New! The S.I.A. "Trecenti" 300 BLK integral suppressor

Got the first unit not only completed but also into the hands of unbiased shooters! More are in production. Typical comments were along the line of "I've used office staplers that were louder than this!" One shooter thought she was getting double taps, she heard the bolt cycle in both dire...
