Ruger GP100 Match Champion in 10mm or .357 Mag

[TXCOONDOG]

I cast and reload for both 10mm and .357 Mag. Have both calibers with a 6” barrel (Glock 40 and GP100).

Leaning towards 10mm just because of the wider meplat.

Of coarse, if the MCR in .357 Mag came with an additional 9mm cylinder then I would go with it (it would be a easier decision).

Use would be for range and woods back up.

Anyway, Looking at both in the Match Champion Revolver, but can’t decide between them and buying both isn’t a option.

Thoughts ?

357mag I think would probably have more stoping power for your bush back up and ca probably launch heavier boolits faster when needed

I say also the 357 mag since you can do more with it if you like.Beside what Cast outlaw stated.

I believe you need moon clips for 10mm which was deal breaker for me.

.357mag would absolutely be my choice.

.357. Moon clips are EVIL.

Have both a 4.2" MC 10mm and a standard 4" full underlug .357 Magnum....both are excellent shooters...

In your case I would say it just boils down to which caliber is more useful for you...a 10mm that will also run .40 S&W or a .357 that takes .38s... They will both handle 99% of woods walking tasks....

If you plan on only running cast bullets I would go 10mm just to be able to make a bigger hole...

Moon clips detract from revolver reliability.

357

I think either will do what you need.

10 allows lil heavier bullets, and better diameter on large game.

357 allows good power large bullet selection also availability. 357 Mag is more common.

I am fan of the 10mm, almost bought a GP in 10 myself. My state requires a 6” bbl for hunting.

IMHO the 357 in a revolver is best under 170g. Velocity droops too much with a short vented barrel for heavier. The 10 is best with a 180g but a cast WFN 200 isnt much longer and can bring excellent preformance to the table. My G40 shoots my 220 Cast right at 1200 fps. You wont see that velocity in the 357 with a 180 unless you get a 8” barrel and load a warm loading.

Moon clips seem to be a bit of an issue, though.

[contender1]

I have one of each.

I USED to think of moon clips as "bad." UNTIL I actually used them and became a revolver shooter in USPSA.

I would say that to choose,,,,, you would need to evaluate the uses for the caliber. Hunting? Brass availability? Competition? Self Defense?
I will say that my MC in 10 mm is a better handing gun than my S&W 646 in 40 S&W in competition.
My .357 is a seriously fun gun to shoot as well.

So, choose which one by the uses matching the caliber & bullet choices.

357 But I am biased. I have the Match Champion in 357 and love the versatility.

I have the match champ in 357 and it is about all I shoot pistol wise anymore.

[lefty o]

i think the only way to really answer the question is for you to buy both. and yes, i am an enabler. LOL

[TXCOONDOG]

I appreciate the feedback. Both calibers are easy to handle, fun to shoot and ok for backup.

I’m going to think about it a while as I’ve been thinking about a 41 mag or 44 mag too.

[35remington]

I have used moon clips extensively. After all that I still think they are bad. The worst part is they increase the likelihood of misfires as in some instances they must drag adjacent cartridges to the one being fired forward lightening the firing pin impact.

For games they are okay. Real life, not so much. Woods “back up” and hunting is a real problem with them. Carrying moon clipped rounds in the field as a reload is asking for them to bend. If I am knocked to the ground and have to fire an upward angling shot....not good. This is where adjacent cartridge drag rears its ugly head.

I'm pretty happy with my 10 mm Super Redhawk. Pick your poison I don't think it matters that much what caliber you get you can make them all work be happy with what you have chosen. Too many people have strong opinions about these things when many things work

[GARD72977]

I have been really looking at the 10mm. cDNN has it on sale

Moon clips seem to be a bit of an issue, though.

If using anything other than 10mm in one of these guns one has to use "thick clips" to assure proper headspacing.

When using .40 S&W with the OEM clips, which are made for easy loading and unloading without a tool, I got 40% misfires when using .40 S&W...with thick clips 0 misfires. When using 10mm the round is actually headspacing on the case mouth not the clip. That is why in the article when the chamber was increased to take the 10mm Magnum there was misfires with standard 10mm rounds...using thick clips would eliminate that.

And personally I can't see deepening the chambers to take 10mm Magnum. It is nowhere to be found and when using full 10mm loads in the mid-frame revolver recoil is all one can ask for.. With the gun as stock one can run 10mm with no clips...deepen it to take Magnums and one can not...

Useless conversion...Bob
