Compression and Olde Eynsford

[SgtDog0311]

Gary, I started out with some magnum primers then got cautioned and went to standard. I'd be interested in thoughts about the use of either with Black Powder, in the 38 or the 40. I'm loading for a 40-63 too. Also about small pistol vs small rifle.

I had a good time at my first BPCR and looking forward to more. I went with my 1200fps load that only had about .035 compression as it printed best on a short range target and didn't have any trouble knocking rams over. But the animals at the OKC range fall easy so I'll still be testing above that compression. Think I'll go snoop around over on the BPCR and Shiloh forums before I load more. Maybe ask some of the same questions. Thanks for your input btw.

Sarge I have also been advised to not use magnum primers in my loads for the trapdoor. With the recommended compression and crimp in Spences book he advises to enlarge the primer hole some and use magnum primers to get enough pressure initially to overcome the crimp and get the correct bump up. I realize these recom's were for the older GOEX 2f so I am gussing that the improvements in powder sort of negates the necessity of those requirements? Has anyone had good results with light or no crimp in accuracy in the TD with original barrel the correct bullet?

Jim, I can't speak to crimp at all since I just lay down the flair with a full length sizing die set to lightly squeeze the flair flat.

I'm just starting to shoot the .45-70. I have two trapdoors a high wall and a Sharps. I never shot to much till just lately. I been working up loads for the sharps. One is with a PP and the other is for a 121 PH. Working up ladder loads from zero to .400" compression using 1.5, 2 and 3F OE, all three granulations like .120" to just under .260". The best load using OE is a 67 gr of 3F OE using the 121 PH Lyman bullet. That load is TIGHT @ 200.
The PP prolate with no lube wad just a .038" plastic wad and 73 gr of 3F OE.
Between .180" and .250" compression is pretty much average from the .40-70 to the .50-90 in 1.5 to 3F OE.

One very good shooting load for me using OE 3fg has been with 67.0 grains and a Sagebrush cast PJ Money Bullet sized to .459 with their lube. 200 yards benched using the SR target results in X's and close inside 10's. This was in Winchester once fired neck sized brass, .060 vegi wad and Federal large pistol primer with a .004 card primer wad. Wiped between shots bullet seated to expose the first lube groove. I do think I'll melt off the lube and use my own lube, it is a bit softer than the Sagebrush and not as tacky. (78.0 grains worked well in my 45-90 with a BACO 535 grain Money bullet with the first band reduced and seated exposing the first lube groove).

[Etienne Brule]

You will really like the OE 2F.
It's all I use in my .45-70 & .45-90.
Gary

Hi Gary,

How many grains of OE 2F do you use in your 45-90 ??

Thank you

I used 82 rg of 2f OE in the .45-90 with a BACO elliptical PP bullet at the Mt. 1000. It shot very good.

[kokomokid]

I was suprised that 81 grains of swiss 1 1/2 only ran 1190 fps with my elliptical 540 grain in my 45-70. Thought it would faster.

[Kurt]

Kid that does sound slow. I don't worry much about the velocity. I used to use a chronograph a lot in the past, but now I just look at the vertical a load shoots down range.

Our friend Kurt has words of wisdom here for many of us that are still learning !
