Just picked up a box of 100 grn. .308 dia Speer "Plinker" bullets in a batch trade.
They are 50% jacketed 50% lead round nose. Anyone load for the 06 with these ever?
I suppose they would be good for fireforming new brass?

I have a good bit of data with surpluse powder driving that bullet to 3200 fps. with fair accuracy.here is some loads with commercial powder.

12.2 gr. Blue Dot, 1500 fps., 6 shot 3/4" group at 50 yds.

24.6gr. Accurate #9, 2250 fps.Deadly at 200 yds.

19.2gr. 4756, 2000 fps. good 50 yd. group.

56.2gr. BL-C(2), 3225 fps, 3 shot 1" group. 50 yds. This was a carbine FMJ bullet. The Speer plinker may or may not hold up at that twist and velocity. Try it and see. So far the reduced loads with this bullet seem to work best

Old age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone..

FYI,

In the .308 that bullet has been accurately pushed at 2600 fps with a load of 4759. That was the fastest that was tried in that rifle. It is suspected that the bar could be raised to a higher velocity and still maintain accuracy of some sort.???? roger

I'm interested too! Have not used a 100 gr in any of my '06s.

bartsche: What surplus powders and loads? I have several surplus powders on hand.

Thanks guys,
Mike

I'd recommend against it for fireforming

I've done a fair ammount of fireforming 30-06 cases
and I'd strongly recommend using heavier bullets for that job.

the heavier bullet allows a greater pressure/time
for forming the case.

My preference when fireforming is for heavy for caliber bullets (180-200gr in the '06) along with a fairly heavy charge of medium speed propellant (4064 or IMR4895)

I have a fairly large supply of old Herters semi-spitzers
(almost a truncated cone shape) and "semi-Round nose"
bullets that I seat to the lands.

Brass forms PERFECTLY every time.

First off ADG is right about light bullets vs. heavy bullets and fire forming,

Some surplus powder loads.

57gr. wcc846 3300 fps. accuracy only so-so at 50 yds.

51gr 7383, some unburned powder, but repeatability not all bad.

42gr. 8208, nice plinker.

52 gr. wcc846., 3000fps. nice group at 50 yds.

44gr Turk 8mm powder, 2850 fps. Not all bad.

36gr. T680, 2150 fps., soot, 5 shot 2" group at 50 yds.

gad this brings back memories - when we were in high school we'd buy 4831 for about 40 center a pound. we fill a 06 case with it, stick a plinker in it take our m-1's out and go jackrabbit hunting. Didn't hit to many, don't even know whether or not the bullet was going straight or sideways, but it sure as hell was fun

I think they make great varmint bullets.
In 30-06 try:
25.0gr 2400
44.0gr IMR 3031
54.0gr IMR 4895
They also tend to do better when driven fast.
