Well i got around to resizing some Remington soft points for 45-70. Pretty easy task.
Now I would like to load them with some Lit' gun powder.
Starting loads should be about 34g. to 35g. I am guessing looking at other posts
on reloading the Hornady 300 XTRs.
Any help with this would great.

IMHO, Lil Gun is kinda fast for a 350gr bullet. I'd be more inclined in the direction of 1680, especially if you have a full sized barrel, as opposed to the carbine. This is speculative as I have never needed to shoot a 350gr bullet for the animals I hunt.

Thanks Hoot. But I meant 300 gr. so I did an Edit to the Title of Post.

OK, I should be a more careful reader. 300gr is more in the ballpark for Lil Gun, albeit on the high side. W296 offers a good solution as well as 300MP.

I do not resize .458 bullets down for my 450b, but I've followed the work of members here who do. I've seen it said that one should have 2 or 3 sizing dies like .452, .451 and .450 to allow for bounce-back after sizing. Then mic (not caliper) the resultant bullets to see which die yields the end diameter closest to what your barrel prefers.

Keep us informed of your results, both in velocity and accuracy.

Thanks Hoot.I have notice that in measuring them that they are about .453 on the first pass thur.
Second pass is .452. I will report my findings.
I have a standard 20" barrel Bushmaster upper.
Thanks again. Mark.

I started the Reloading process with case prep., then swaged the bullets to .4525 dia.

I started with 34.0 gr of LiL'Gun for ten rounds and went up a half grain in weight for each ten loadings.
Finished off at 36.0 gr for final loading of ten. For a total of five different loading.

Now to the range for testing.

Nice reloading bench dude.

Thanks . Here is a other photo of the set-up I have.

Mark-
I'm curious about your starting load of 34.0 grains with the resized bullets. That's about 2 grains higher than the maximum load for Lil'Gun provided in the Hornady data for this cartridge with a 300-grain bullet.

Is there some aspect of these bullets, of your rifle, or of something else, that indicates 35.0- to 36.0-grain loads might be good starting points?

Thanks for any insight into this. Let us know how your test shooting turned out.

Thanks.

I started at 34 grains with the Speer deep curls and was getting a lot of soot and I had one hang fire with 7 1/2 primers. I bumped up the load in 1/2 grain increments making it to 37 grains. The recoil was quite brisk at 37 grains and accuracy was terrible. My 100 yard group at 36.5 was about 2 inches smaller, right at 1 1/2 inches. I had no pressure signs working up to 37 grains.

I started my work up after a member had done some hunting with the deep curl bullets and wanted to give them a try. I believe another one of our members posted quickload data and said 34 grains was a bit light on the powder charge but don't quote me on that one. I'd have to dig thru all the posts.

Thanks,
B.
