Looking for loading advice for S&W 610 10MM


October 7, 2003, 12:23 PM
Recently traded for S&W 610 6.5" barrel. Looking to reload for it. it is a new caliber for me and not sure where to start.

I will probably load both lead and jacketed bullets. Does this revolver prefer any one bullet weight over the other?

What powder choices seem to work best?

Thanks for input.

I haven't loaded for 10mm or for the 610 but it's the 1st S&W revolver I've really had an interst in. It should do well with the same load data as the 10mm automatics use.

Now .40 S&W I know a bit better. I'd recommend the lighter .40 bullets for best saftey margin - recoil - accuracy. Power Pistol and Universal work well with the .40, it's a lot differant with the 10mm.

It has about twice the internal case volume if they're both loaded with 180 gr and you can safely load the big .400 bullets like the 200 gr.

What are you going to be doing? Pins, punching paper, hunting, all of the above?

Planning on using for game from jackrabbits to deer.

Some plinking for practice but not competition.

You're going to LOVE the 10mm, especially in the 610- some of the most accurate Revolvers/cartridges ever produced.

Had a Deputy friend who has/had one (now 2 the last time I talked to him). He got the 5" when they first came out back in the '90's.
He scoped his with a Nikon pistol scope, a 2-7 or so, variable.
He showed me the group he shot with some 200gr Hornady XTP's that I had reloaded for my 1006 S&W I had sold. He had a 5 shot clover leaf, and one called flyer that opened group to 2", fired at ......100yds!
He claimed he had spent most of his life trying to get rifles to shoot that good and often failed.
He later got a 6.5" version when word got out they were discontinuing them. ( they did for a while, then reintroduced them).

You will get good loads with both jacketed and cast slugs.
Depends what you're looking to use them for.

For inexpensive plinking the cast bullets are best, and also for high end loads too, with appropriate powders.

Jacketed bullets of course are excellent.

www.glocktalk.com has a forum just for reloading the 10mm, I suggest you start there for additional information and data.

Keep in mind that the Revolver does NOT have the unsupported case head issue that some Semi-Auto's have so you're not as restricted in loading flexibility, both at the top and bottom.

I prefer the 175-180gr bullets for cast, and the 150-155gr jacketed. I have killed deer with both the 10mm and .40, and prefer the lighter weights in jacketed bullets. I have yet to recover a bullet from a deer with 155gr to 200gr HP's, so don't worry about lack of penetration, except perhaps the 135gr JHP's.
My favorite slug is an old Lyman mould that was produced back in the '60's for the old Herter's .401 PowerMag cartridge. It is a true Keith style SWC and casts at 178gr from wheelweights. I have shot 6shot cloverleafs with it at 25yds both with above noted friends 610 as well as the 1006 I owned.

Some day, I'm going to get another 1006.

I acquired my 4" M610 several months ago and shoot both 40SW and 10mm at paper targets.

I have been quite perplexed by the disparity in reloading data. Some reputable reloading books show a 10mm starting load that is the max load elsewhere. Recommend cross checking all load data.

I have used Win 231 and Hodgon Universal with good results on hard cast and plated bullets of 165-200 grains. However, I'll be buying some Accurate #2 and #5 at the next gun show because Accurate seems to publish more complete data (especially for cast bullets) and the listed loads in third party reloading manuals are in better agreement for Accurate powders than for some of the other powders.

I have been to the Glocktalk forum and looked into the 10mm data. Mostly about semi autos I find.

I didn't know if those had to be lighter loaded because of chambers. Was looking for info on load data for revolvers.

I saw in Brownells catalog they have a couple of different full moon clips. Which are best?

What other accessories and smithing might I consider?

Also looking for a holster for this one. Actually would prefer 5" barrel over 6.5 but can't seem to find one. I traded a 625 5" for this and liked the way the 625 handled.

As always, I am happy to hear about others experiences.

Alliant Power Pistol is a very good 10mm choice; Blue Dot, N350, and 800X also work well.
Bullets everywhere.........but 200-220g slugs can be very accurate (even at reduced 'target' velocities).

Hornady 155g XTP
Starline case
1.250" OAL
CCI300 Primer
9.0g AA#5

Not a hot load by any means but in my 610CH it shoots about 1/2"-3/4"

If I had a 610, I could seat the bullets longer, and make room for more powder, so I could use slower powder.

I have a 25-2 revolver that shoots 45acp. I have learned to seat long and Lee facory crimp. I can use LIL'GUN powder and long bullets.

I have found that AA#7 works well in my Delta Elite with its conventional Bar-sto barrel - use caution, however. I found I could get 155's up to 1350 fps - I got as high as 1420 fps, but the cases bulged over the feed ramp, and I backed off.

One point that always bears repeating - if you keep loads around for one gun that could disassemble another in the same caliber, make darn sure you can easily tell them apart!

I would like to have a 610 also, but would be very careful to avoid loading anything hot that would find its way into the fine, accurate Colt.

does it cause any problems shooting a lot of 40 rounds in you 10 mm.like sticking cases when you go back to 10mm.how much trouble is it shooting with the moon clips vs the speed loader say with a 357 mag,thanks,keith

I load 1omm for a Delta & a 1006. If you want high perf. loads you need slower powder like AA#9 or BlueDot. You can go jacketed or lead, but if you are going to exceed 1300fps I suggest jacketed. 10.5grBlueDot o/ 180grjhp should get you in the 1250fps range.

that was what I was going to suggest. Actually, that is the exact load I use. Found 8# of Blue Dot for $49.00:D

I have a Delta Elite and G20. Blue Dot is slow enough that I think you'll fill the case before overload with a 180 gr. Also, if you push the older powders closer to max they seem to burn cleaner. Watch metering...the flakes are pretty big and charge weights will vary a little.

I also use AA5 in just about everything and it works, just that the Blue Dot gives more power more safely. AA5 meters much better in my Dillon.

To me, the value of the 10mm is the ability to use heavier bullets than the 40 SW.

Blue Dot or 800x with magnum primers for max loads.

where can you get bluedot for that price,thanks,keith
