Test of Hubel Sabot and other ammo, with pics

[Carryacolt]

Cpileri,
Did you get the copper slug from Greg?? He had some a while ago but I think the were 780gr plu or minus. They would make a great home defence round.

Yes, Sir!
Not cheap, but i just had to have one!

about the weights of big guns, above:
So i managed to add some weight to the forearm, and its now pushing 12+lbs, with scope. SO it ought to be comfortable in the manly, British, double gun sense to fire up to 5800 fpe or even 7000fpe if you take the "new weight" column.
Calculating just a few loads from the "inspired" threads and accumulated list of loads, i got:
600gr Dixie Slug @ 1850fps (w 132gr Re-17 or 90gr IMR 4227)= ~4500fpe. and
730gr @ 1650fps (using 82gr 4227)= 4400fpe
and onward...
RMC 3.5” brass
85gr IMR 4227, 209 primer, X12X, 2 (two) x 1oz Brenneke KO slugs stacked, 1600fps = ~2500fpe EACH (=5000fpe)
140gr IMR 4227, 209 primer, 437gr BPI sabot slug, 2600fps = 6500fpe
220gr Re-17, 420gr in BPI sabot, roll crimp, 2900fps =7800fpe
200gr Re-17, 715gr Jacketed fullbore slug,roll crimp, 2500fps = 9,900fpe- THE winner!

Keep in mind, these loads need psi testing. But even if they are pressure safe, looks like some are still going to be uncomfortable from a 12lb gun. of course, I am basing this comfort only on the assumption that the weight of old double guns is indicative of what folks found tolerable from a recoil punishment standpoint.

Test #3 very soon!!

The 4227 loads of 90gr tested peak pressure same as 4759
and 130gr Re17 about the same. For plastic cases.ED

So I am just being a big pansy?

Your Just careful. But the 90gr 4759/4227 and 130gr Re17 all average about 14,700.
Which is why I like them, lots of room to work.

Also over the years we found that 4759 better than 4227 as
4227 misfires if cases and charge get cold. So I don't use it now.

And with our sabots all using lighter slugs(350 to 500 gr) than the tested 600gr Dixies
there is lot of room for safety.

And I'm finding that for some guns(wide lands, smaller bore) that 4759 is better
than Steel.Easier on sabots. more accurate.Ed

[cpileri]

So, were these loads all in the 14.7kpsi range:

Top RE17 loads in NEF- Don't go below 100gr of Re-17 in 12ga cases!
3.5" RMC brass--385Gr JKT --220gr Re17
3.5" RMC brass--Hubel Sabot with 400gr --- 220ge RE17
3.5" RMC brass--715 gr JKT and 720 gr hard lead-- 200gr RE17
3.5" RMC brass--870gr hard lead- 180gr RE17
3.5" RMC brass--1040gr hard lead - 170gr Re17

??
thx again for being so generous w your data!

No those brass ones with RE17 running 18-25,000 psi. Which cases handle ok
and my Nef extracted ok.Ed
