Compression and Olde Eynsford

[Mike]

Sandpoint is a might good place to visit. Give'em my regards while you are there. Shoot sharp, Mike

Lots to learn hear and what I have to work with is the 1 ½ so that’s what it will be for my very first BPCR match next week. This summer I'll start over with some 2f.

So far best accuracy was this at 42gr and 1209 average velocity. This was at 50 yds since I don’t have the eyes to do load development at 100yds.


Thinking with the 16 twist 1209 might be improved on for bullet stability at the longer ranges - I guess I’ll try and find time for test loads at ¼” compression. 50gr works out to a ¼” so I’ll try some 50, 49 and 48 and hope for something a little better and that gives me more confidence at the distant targets. Wish me luck. I could probably throw rocks at the chickens and it wouldn’t make any difference but you gotta start somewhere.

Mike, I love the Northwest. I built a cabin just north of Sandpoint about 20 miles and spend a good part of the year there. Nice to wake up and find a moose standing 20 yards from your kitchen window. Used to spend a good part of the winter there too but got six grandkids now down here in Oklahoma and when my grandson started wrestling the winter trips had to stop since we are a wrestling family. Can't miss those tournaments when you boy is laying his heart on the line when the whistle blows. He wrestled 70 matches this year and took second at state a couple weeks ago. My old body is getting punished trying to do moves for him in the corner.

Hey Sarge, That is an awful pretty area. Keep the moose happy! And you can drop down to Buffalo Arms for supplies. Shoot sharp, Mike

Well I've tested from 36gr to 50gr now. Got a couple accuracy nodes but with the last batch of 46-50g I made the obvious mistake of introducing a second variable by seating the bullet out a 1/3rd of a lube groove so I'll have to repeat those. Other variables I believe I better check after this (my first) match this weekend.
Variables to test:
-Half grain increments
-Magnum primers
-Seating depth
-2F
-Lube
btw... compression goes from zero to 1/4", my small seating depth change notwithstanding.

I see there is a lengthy OE thread to review so I better go check that one out.

Give some std primers a try.

This is a supposition type question has anyone yet shot a trapdoor with a full load 70grs of 3f old e with the 500gr gov bullet and if so what were the results?
To do so would require a lot of compression on the powder would it not like it much?
Not that I intend to do so unless it is workable it would give a boost for shooting LR out to a 1000 or just result in a bunch of in accuracy's?
Still new to this haven't shoot the rifle yet still working on it be a month or so still need to pick up some bullets for now and primers have brass.
Last would this be an possible over pressure load for a TD?:

I don't think 3f eynsford will work for beans in the 45-70. If I were going to try it I would use just enough to make firm contact with the wad and the base of the bullet.
2 or 1.5 at 68-70 grs be a better pick iMHO.

Thanks Don you have recommended using 2f in your previous post. I have a question you recommend using a wad under bullet whereas in Spence's book he doesn't feeling that having the powder in contact with the base of the bullet is better to get it expand better for the 3 groove TD barrel for sealing. Qurious is all.

Try it both ways, the target will tell you the truth.
