So I took Jerry up on this and have had positive results using .311" PRVI 150gr FMJ BT. The best so far is 0.397" (still at 50 yards). The rifle seems to like the bullets seated out past 2.950" with the groups consistently better than below 2.9". I have only worked up 3 loads so far, all using H4895. A good start!

I guess my targets are a little Mickey Mouse eh? What would you recommend? This is what I'm looking through:

Well, that is very promising progress. Try them at 100yds and if the groups stay nice and tight, 311 or even 312 is the way to go.

When a bullet is too big, pressure signs happen RIGHT NOW and accuracy is shotgun like. You'll know real fast.

There are a variety of nice match quality bullets that will fall into this diameter.

Hrn offers a few 311 and 312 bullets
Sierra and Speer offer several 311 bullets.

With the target, try one with a nice wide cross so that you can center your reticle and know that it is in the same spot each time. Aiming into a circle will produce some POA error

With a low mag scope at 100yds, that can be +/- 1/4" so make the target fit the reticle.

Just make different widths until you find one that fits the reticle nicely.

No but I plan to. Need to find a piece of lead that's the right size but have no idea where to look for one. What did you use?

Lead fishing sinker, shaped like an egg with a hole through it. Get a pack from Wal Mart or Cambodian Tire, should be at least 8mm... or whatever the standard size that 8mm converts to.

. My groups at 50 yards were about 12" using iron sights and my own handloads.

Finally, today, I got down to less than 1" (at 50 yards).

I had the same issue with a 91/30, so I took it in and had it re-crowned for about 40 bucks. The holes touch together at 50 yards now.
