triple 7 and conicals

[corey012778]

planning a long session on tuesday. taking both my usak and new englander. maybe the apex if I get some bullets for it.

checking to see how much powder I have. only powder I have a lot of is triple 7.

new englander is going to be all round balls to get it sighted it in. thus pyro rs. with my usak, I am going to be shooting powerbelts, both weights of lee reals, some great plains, and fpb's. I was planning on using pyro p, but I don't have enought for the amount I shooting I was planning, 25 shots at 85gr of pyro p (usak's fav. powder charge) and only have maybe 1/3 of a bottle.

so, with triple 7, should I still try it with the 85grs or lower it 5 to 10 grs?

With triple 7, lower it to 70-75 grains if in 2F form.

I picked up a tin of win #11 mag, I won't give them a try this range session. too many unknowns. maybe on the next one where i am planning on resting the usak and apex scopes to bulls at 50yrds. then work 100 yrds out of them.

70 to 75. check. set my charges up tomorrow night. just hope my new englander shoots better now.

Corey,

Do not know if this will help with anything but thought I would share...

First I shoot T7 in all of my sidelocks. I do shoot T7-3f, it seems to work really well for me. I have gone to 3f powder because it will shoot reliably in really cold weather. The 2f works fine in warmer weather.

I have two LRH barrels with a 1/28 twist mounted in TC Renegade stocks.I shoot the 460 grain Bull Shops from these barrels. Both barrels shoot extremly well with 90 grains of 3f, then a .125x.510 shot card topped with the MTNex.

I also shoot the same bullet in my factory Renegades with the 1/48 barrels. I do reduce the charge to 80 grains in the 1/48's.

Here is a target i shot awhile back. It is not great, but for me and my eyes with open sights it works!

In the testing I've done I found that there was very little difference in velocitybetween Pyro P and 777 2F. Which kind of makes sense in that 777 2F is about 15% hotter than Pyro RS and Pyro P is also about 15% hotter than Pyro RS. I found that the difference in velocity was typically less than 50fps and often less than 30fps for equal volumes. I haven't tested a lot of different bullets sizes with both powders but the ones I have checked fell into that range. Give it a try and see what happens.
