Compression and Olde Eynsford

I don't worry much about the velocity. 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 !

Jim,

I'm a slow learner. It took me 60 years to get to this point and I'm still erasing and redoing

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

Gerald Canada

WELCOME to the forum
83gn(weight)w/060 'poly' wad and a coffee filter paper wad over the primer at the bottom of the case.

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.

That doesn't sound 'rite'.
Were you using new/fresh batteries in the crono?
My 83gn 'O'E load in my '90, is run right at 1350fps.

Gary, your velocity could be the results of thin Palmdale air !

It does sound low. If I remember correctly, my 83gr Swiss 1.5 load runs about 1280 fps. That's a 535gr GG bullet in a 32" barrel.

81 gr. of OE 1 1/2 and the 530 money bullet clocked 1340 at Raton from the CPA.

Another run 90*f day with a little thicker paper (25% cotton eaton) and a different primer shows 1218 fps with 543 gr brooks patched to .450. Same Swiss 1 1/2 at 81.0 gr. Muzzle to first screen 10 ft.

[Gunlaker]

There is something strange going on there I think. That's almost exactly the same as my patched .45-70 load except that I use a 535gr bullet and it's definitely faster than what you are seeing. My chronograph is further away too.

More importantly, how does it shoot? :-)

Well, I've done some more loading with the 1 1/2 in the 38-50 and am settled on 46gr with .130 compression for the last BPCR here in OKC if I get back to Oklahoma in time.

I did stop at BA last month and picked up enough 2f OE to prove that out in my 40-65 next. I'll post progress here after November and hunting season.

The range is at 4K'(ASL). So maybe.
