Years ago i spoke to him, he knew a lot, also spoke very cautiously.

I like that in bomb disposal techs, reloading gurus and investment advisers to mention a few. ;)]]> Reloading Methodology oafpatroll https://systemz.online/reloading-methodology/243-subsonic/paged/2/#post-1925 https://systemz.online/reloading-methodology/243-subsonic/paged/2/#post-1921 Sat, 26 Nov 2022 06:30:26 +0000

A 6mm 90 to 100gr bullet will have double or more momentum than a 40gr .22 bullet and will therefore give better penetration. This will be of benefit when a skull has to be penetrated.]]> Reloading Methodology Tripodmvr https://systemz.online/reloading-methodology/243-subsonic/#post-1905 https://systemz.online/reloading-methodology/243-subsonic/#post-1904 Sat, 19 Nov 2022 21:43:50 +0000 New user here based in PE. Looking to learn and share.
Any further developments on this topic? Would be interesting addition to a 243.
If the target animal is not too big a plain subsonic silenced .22 is hard to beat.

I have some serious misgiving about trying to load an overbore cartridge (including the 243 Win) to subsonic velocities.  There are many opportunities for mishaps here.

Generally, subsonic loads like bullets that are shorter (lighter) than what works at normal velocity levels.

My suggestion would be to go with reduced capacity cases, to prevent all the possible dangers that can damage your rifle.  Unfortunately, these are expensive.

A 303 or similar rifle converted to a handgun case (e.g. 32 S&W Long, 32 H&R Mag, 327 Federal?) and loaded with +/- 160gn cast bullets should give you many hours of quiet plinking and varminting pleasure at a very low cost per shot.
I suggest 303 as you can use the original barrel and just set it back and re-chamber.  This should keep the cost manageable.  I imagine you are too much in a hurry to go through that process now?

My own low-cost low-noise rifle is a 44 Mag built on a Lee no4 action salvaged from a scrapped 303.  The 44 case head fits the 303 bolt face perfectly.  Probably a bit too much punch for your purpose.

**************************
From past experience, I just would not even try down load to sub sonic with necked down cases, or magnum over bore cases. I think the perfect sub sonic cases are straight walled cases or second best necked up cases, like the  8mm 06 or 6x45mm (6mm in a .223 case) these cases are just so much easier to load for. We tried with MP-MS 200 and I think it was 321 in 243 cases and although subsonic was easily obtained, absolute explainable 120 fps jumps in velocity and shot report made me think that we were perhaps playing  beside devils and demons on some shots.]]> Reloading Methodology Treeman https://systemz.online/reloading-methodology/243-subsonic/#post-1893
