Home Forums Hunting & Shooting Handguns SRH 10mm

I've seen way too many significant failures with XTPs to even consider that route. All "hardcast" bullets aren't created equally. How big were the meplats on the bullets you used?

Someone mention meplat...

Not 10mm, but .45 Colt.

I shoot these Thunderhead 270's in my .45 Colt. Now, they do hit with a whallop.

The 10mm on the right crams most of its 200grs. into the powder capacity, despite the best effort of a wide, weight forward design. It BARELY fits in the confines of its magazines and would fare better if it butted up with the rifling upon chambering.
Done in a SRH with a bullet similar to the 300gr./45ACP revolver load, no doubt it could be improved ballistically as well as shoot better in the wheelgun. Maybe add another 50 grains.

I'd much rather depend on a dual alloy cast bullet than anything a factory is going to cook up built around velocity and range limitations, IF I were to find plain old hardcasts lacking....

Yep.

2 for me

i have been shooting 10mm in a ruger blackhawk convertible 10mm/38wcf for quite a while.
With that long tube on the blackhawk it gets velocities right smart up there.
i would have to check my notes but i am semi remember clocking either 1800 xtp's or 200 grainers in the 1400fps range.
pleasant to shoot too.

I'll reply with meplat specs if I can ASAP. Bunny run offs were mostly .452" in several 45LC Rugers. Often the Keith style 300-315grn. Those were supposed to be the Cat's Meow 20 years ago

Back to the topic of the 10mm and HC. For the auto loaders.....isn't there going to be an issue with crimp and grooves and function?

At one time I believe StarLine made brass for a 10mm magnum, I think I even got A reloading manual around here with data for it. Now that would be a versitile revolver. 10mm magnum, 10mm and 40.

That is similar to what I have been seeing. I was looking for the most accurate load from the 10mm revolver with a 200 grain bullet and it settled in with a SD of about 9 fps and grouping just over 2" at 50 yards. The velocity was 1421 fps.No signs of any pressure and very easy case ejection.

I think the SRH is overkill for the 10mm auto. That's a big chunk of metal to tote around for the least ballistic potential in the line. I have a SB Hunter in 44mag and that is about right. It will group 2.5" at 100 yards with a scope, but it is a big heavy beast to pack in the field. But, variety is what makes the world go round and as usual Ruger is offering something that nobody else is or will.

I did just pick up a Tanfolglio Witness Hunter and I'm looking forward to working up some loads with 180 - 200 gr cast and the XTPs. It will be easier to carry in the field than the SBH and still pack enough wallop for in close whitetails and varmints. I also like the single stage trigger which needs a bit of a tune but it's light years ahead of any Glock I've tried.

I would love to see a GP-100 in some sort of "Hunter" configuration. Maybe in .357 and 10mm.
