Speer has a 20% rebate going on until June 30th. On $100+ orders select bullets. Just ordered 500 125g tnt's and 200 130g hp from Grafs
That reduces price to $60 for 500 TNT's.

Default OAL for the tnt

Is there a recommended overall cartridge length for the 125 grain TNT? Just received some from Graf's and gonna give it a whirl. I have only loaded 150 and 168 in the past. Didn't know how fussy the garand might be with the smaller bullets and cartridge length.

Speer says 3.1" COAL. This is about right based on my experience. You do not have much leeway with the short bullets. With all the 110-130gr bullets in the 30-06, 3.09 to 3.1 inches is it. Good Shooting. ...

Default Tnt

Thank you. I will be giving it a spin shortly. I have a garand lead I have never shot and it will be the first to give it a go.

Thatís what I seat the TNT. 3.10 appears to seat it past the ogive.

Iíve tried 3.10, 3.15 and 3.20 in the M1 and didnít see any difference, all functioned and accuracy is good, so I settled on 3.15.

Geoff,
I shot this with my 03a3 (prone, slung up) this past weekend. My standard 125gr TNT load. After the match I shot with you I lengthened the oal to 3.20. I was thinking it might help that feeding issue. Seems to be fine and feel there is enough bullet in the case. This is the load i will be shooting at Perry in my wood guns.

BTW....if you remember I had to hold 12:00 because my rifle was shooting low? I came up 1 little notch and the POI changed this much using a COM hold. Tempted to glue that sight in place so it won't move!

Keith

Dang Keith, you have this nailed! Can you remind me what your powder charge is, 49 gr H4895?

I would weld that sight up!

I shoot 50grs h4895 with mine. I know guys that shoot from 46-50 with similar results. I also used prepped HXP brass here. I have used Lapua, Win, Rem, HXP and honestly don't think it matters at only 200yds. Mine do get full prepped regardless of which headstamp I use. I have had a lot of split necks with Win. I pretty much default to HXP. Nothing fancy but it WORKS!
