Run a comp for a 240 PF?

[Any Cal.]

This isn't an Open gun question as much as a comp question. What might be expected from a Jaeger comp running on a G20 with 220s @ 1100, with no other mods? Weight from mag is a bit higher w/ 220s, but gun is still fairly light. Any ideas? There should be plenty of gas to work it, but am wondering how much help it may be due to the high muzzle flip in stock form.

Thanks for any help!

What powder do you intend on using?

I think you'll be at or beyond the point of diminishing returns.

The felt recoil in the hand will probably be harsh while the muzzle will "flip" down instead of up if the comp is any good.

IIRC shooters back in the day had that issue with the 9x25 round.

Hopefully more knowledgeable shooters can chime in on this one.

Most of my history info is from a few guys that's been around for quite some time.

[Whoops!]

That particular comp with that load, regardless of powder, will not cause the gun to flip down. The Jaeger comp is pretty ineffective in my experience. That being said, as long as you use a slow powder like N105 to make that power factor, expect the muzzle rise to be lessened substantially. If I had to guess a percentage, I would guess 40 to 50%. That being said, it is a hard guess to make because almost all of my experience with that comp has been with light bullets and I'm compensating for the fact that there won't be as much gas with the heavier load you are using. Also, it largely depends on what type of grip you are using with regard to how much it rises now and will rise after installation. The main thing is, the muzzle will drop back down to the target much faster regardless of how much it rises.

I can't comment on straight back recoil, as I've never been bothered by it regardless of load or platform. That being said, I don't have any experience with the 44 mag derringers or scandium magnums.

Powder is H110... Right now recoil in the hand is pretty firm, and even with a firm grip muzzle rises to 45* or so, then pulls my forearms up a bit. I am not much of an auto shooter, but it looks like the gun is in recoil for about .5 seconds on video. I can probably bring that down some w/ my grip, but it is a handful.

If the comp was not any help, I was considering either cutting it down shorter so that it would be less effective, and just letting it 'help out', or else running a longer barrel with porting on it. I figure the longer ported barrel would be less effective, but may soften things up just a bit while increasing the velocity some.

-Edit- It wouldn't have to be the Jaeger, the Carver looks like it has a couple more side ports, it may be a good candidate.

Depressing to hear the Jaeger comp is ineffective.

[Whoops!]

I felt the same way after I bought it. It works, don't get me wrong, just not nearly as well as most 2011 offerings. I feel the major downfall on most cheaper polymer platforms is simply the lack of a very efficient comp system, rather than anything specific with the operating system. I haven't tried SJC's "Major" comp however.

I would try a lighter bullet @ higher velocity. I used 152 gr. .45 cal. @ 180 + PF and they worked great in an early single port comp.

FWIW

I am really trying to make the gun run well with that particular load. Would there be a way to go about doing so? Would a longer comp or maybe a steel one make things happen?

SJC can get you their 11 port major comp for 10mm, just give them a call. It's a very nice comp.

[Whoops!]

Don't get me wrong either, any comp will take a significant amount off that load. Just not necessarily as much as a good 2011 comp and don't worry about the muzzle potentially dipping.
