I would and have shot 62 grain through a 1/9 with fair to good results, but I wouldn't do it with a silencer.  I would use 55 grain.

A baffle strike will cost you way more than a few boxes of 55 grain ammo.

Just my $0.02 worth.

62 gr are fine in a 1:9 with or without a can.  62 grain(non tracer) is not long enough to cause a problem.

I would agree, except in certain instances. Some 62 grain ammo out there has the NATO SS109 type bullet which has a lead core with a steel penetrator at the nose, then the copper jacket or gilding. SS-109 is Fabrique Nationale's (FN's) name for their 61.5 grain bullet with the steel penetrator in the nose.

If this SS109 bullet is balanced, as is all NATO accepted ammunition, then it should be fine. However, there are many civilian manufacturers of SS109 projectile who may have less than stellar quality control, and if the penetrator is even slightly off balance it can cause unpredictable results. M855 for example, uses the SS109 spec bullet, but not all cartridges with SS109 bullets are M855.

If you know for a fact that the munition you are using does not have the steel penetrator or is good quality ss109, then it should be fine. that said, I would not trust any russian made SS109 projectiles with a $$$ sound suppressor.


The diagrams below show the composition of a cartridge with the SS109 specification projectile, and the SS109 specification projectile itself, you can see the steel penetrator placed at the tip of the projectile, under the copper jacket. There have been cases of the penetrator being off center enough to cause less than predictable performance in cartridges with commercially manufactured SS109 bullets.
