Old age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone..

Thanks Roger, sounds like some fun loads. I've got a couple 222s, a 1st year 700 and an early 722 single shot 40X. Both shoot extremely well. I think I'll try some of your loads and see how they work.

The load with the 1680 was a real surprise!
The blue dot load will allow a double charge without spill over. Just a word of caution.
The 2400 loads were not as sooty as I thought they'd be!
Performance like this from this winnie barreled rifle was a true bonus! It seems to just get better every outing and that's with an El Cheepo BSA scope! roger

I've had great performance from 13.5 grains of Blue Dot under a 50 grain HNDY SP in a .223 (2850 FPS and 1" @ 100), so your loads sound about right for the slightly smaller .222 case.

Double charging is possible to do and would be hazardous to your health, but so is sticking a .270 Win in a 7mm RM and pulling the trigger. I've never done the former in 45 years of reloading, but I've seen people do the latter.

I'll bite on this one Stony! what happens?? Don't see the danger. I mean really I don't. roger

The 270 is long enough to be held against the bolt face in the 7mm chamber, so it (usually) will be set off by the firing pin blow. The 7mm chamber is large enough in the area just ahead of the .270 head that the .270 lacks sufficient elasticity to expand all the way to the walls and will rupture, thus filling the chamber and action with gas. In most guns this isn't a catasrophic failure, but likewise, many actions will allow gas to shoot backward through (or around) the bolt and into the shooter's face.

Ok I see where that might be possible. Open question: does any one know if this ever happened? If not I really may put on my face shield and try it. This is not meant to be a put done . It'll be a genuine search for knowledge roger

Step 1. I dropped a fired .270 case int the Stevens mod. 200, 7mm Rem mag.,closed the bolt pulled the trigger, opened it and the case was surprisingly extracted and ejected. The spent primer appeared to have a deeper indention.
step 2. Did the same thing with a primed case and it fired. The primer was flattened and extruded .014" beyond the case, showing excessive head space but, in this rifle, not enough to preclude ignition.This indicates that the first part of Stonecreek's postulate is spot on.
If I can remember the next time I go to the range we'll try firing the .270 in the 7mm Rem Mag.
The head space thing kinda threw me for a loop. The .270 shoulder shouldn't even come close to the chamber shoulder. Taking some neck diameter and case measurements indicated that the once fired .270 case was hitting where the chamber neck stopped and the throating began .Sure enough the .270 case had a slight crimp. I than ran a number of .270 cases in and out of the 7mm. Some extracted and some didn't. The ones that did not were .010 to .020" shorter than the original cases. The ones that did extract showed the crimp effect.
Going a step further the long and the shorter .270 cases were Full length resized. They each grew about .010" in length and would extract. Bullets were seated in each and they both would extract. Neither case was chamffered ,ID or OD .
I guess nothing is left to do but the acid test. roger

I'd be using sandbags and string instead of a face mask.

Sounds like a plan to me! roger

Bartshe: Yes, I knew a guy who owned identical Remington 700's in .270 and 7mm RM, both of which he had at the same time at the range for sighting. He inadvertantly placed a .270 round in the 7mm and touched it off, resulting in the blown case I described, and blowing his face full of escaping gas (thankfully, without permanent damage to his face or eyes).

Afterward, he admitted his mistake but extolled the virtues of the 700 action as being "extra strong" and swearing that he would have been injured or even killed if it had been a "weaker" action. Of course, he had no idea that the failure had nothing to do with excessive pressure or that his lack of injury had nothing to do with the "strength" of the action -- just with how gas from a case failure is diverted and channeled. I'm not sure if the Rem 700 is better or worse in this regard than other actions -- I just try to keep .270 rounds out of any 7mm RM chamber.

Stoney, Did he have any trouble extracting the case? With the amount of brass expansion I can envision the case rupturing leaving some of the front end in the chamber.
also can see at this point where it might be prudent to accept your observations and forget about reinventing the wheel. roger

I have seen the same .270 in a 7MM Mag bone head move. In this case the guy had a pair of BARs. The blown case bulged the BAR receiver and blew the magazine out the bottom.

Great information! Thank you.
This thread may have taken a little detour but from what I learned it was info well presented roger

I repaired a Ruger 77 in 7MM because a fellow got to excited when running his pasture.The rifle shot the 270Win without any problems but the stock and floor plate was toast.
The brass came out without any problems and he had just a few shrapnel witness marks on his face and arms.I think he also ruined his shorts if I remember right.
So if you do this[just for scientific purposes]just be careful.

I read and believe and am not going any further. roger
