I sent an order in for some cast bullets from...western......10 days now and no bullets and no replies.
BBT is who you used?? think I will try them.
I am VERY interested in the results you get.
Appears from the photo you can seat them out to touch the rifling??

This bullet will seat out long enough easily that i cannot chamber it in my Competitor. Billy Marr specifically mentions that you should be able to reach the lands in a TC barrel.

Here is his site > BBT Cast Bullets

He sent me 50 of these to try for $7.50 including shipping!! I told him i was sendin payment and he mailed em the next day!

If these shoot well, i am thinkin about gettin 500..... These should also work well for IHMSA.

H110 in the 7mm TCU?????
Since one of those Milsurp companies goofed and sent me 16 pounds of WC 820 ( I had about 6 pounds at the time already)I am begging for uses of H110.
Tell me more!
I am loading Lee 135s for now!

Lyman says for their 135...

H110 14.4 (1676fps) - 18.0 (1944fps)

Velocities are in a 14" barrel.

If you need more info or data for other bullet weights, send me an e-mail and i will take pics of the pages and send em....

Nice looking loads! What scope or sights are you using on that barrel?

Thanks Sean! I have a Burris 2-7 with Posi-lock with Competitors STEEL Universal (cross slot or dual dovetail rings) base (pic below) and Burris Zee rings. I like the scope a lot but the jury is still out on the freakin posi-lock. I have other Burris variables and no lock and dont seem to need it....

It will be interesting to see how your pistol does!

For what it is worth, I do not like the Burris Posi-Lock scopes. I really don�t like Them! The Posi-Lock adjustment knob is thin and easily damaged during adjustment, and always seems to move zero once you tighten it down, which requires a bit of guess work in estimating and allowing for the shift while sighting in.

I have never noticed my handgun or rifle scopes to change point of impact due to adjustment knobs etc moving under recoil, but rather due to poor mounts/rings etc so I think that in ways the posi-lock is alleging to fix a problem that is for the most part not broken???

H110 and Lyman cast bullet load.
Is this in their "new" cast bullet loading manual?
Whatever it is I will just buy a copy so I can look at other such loads!

I did get the chance to test these loads today!! I do NOT have anything great to report as both loads ran in the 1" range for 5 shots at 50 yards!! I did notice that all four 5 shot groups showed smaller 2 or 3 shot group and then another group slightly away from the other. I believe that this freakin scope is changing POI. I had suspected this when it was on my Fireball barrel as i was able to obtain better groups with a Burris 1.5-4 @ 100 yards than i could with this 2-7. I have loaded up some more test rounds and am gonna try a different scope. I hope to get this posted here this week..... [Frown] Both loads were very clean and there appears to be NO lead in the bore. I will know when i clean it later.

MSSmagnum,

For what it is worth, in addition to my own experiences, I recall that Doc Larry Rogers who frequently used to write in the HHI Sixgunner, complained of a Burris 2-7 Posi-lock that shifted POI. Seems like a problem that is a frequent complaint, at least frequent enough to really suspect the scope.

Sean,

I have a Leupold 4x or an older Burris 2.5x-7x (with no posi-lock) that i could try also. I am going to try that first...... While i have the scope off i am going to check those rings too! I have had trouble with Burris Zee rings on guns with heavy recoil but i wouldnt exactly say that the 7tcu has heavy recoil..... We'll see.....
