Had a good day at the range.

I finally got around to shooting through my chronograph today. I am loading a 400 grain cast boolit over some 4198 and it is going about 1560 fps or so. Does that seem normal?

I have to load up a few more rounds as when I got home my gun fell over and broke the front site, so I had to go down to the local shop and get a new front sight and a rear peep. Now I have to go back out Saturday morning and sight in with the new sights.

Post us some targets to look at! Pictures are worth a thousand words! Somebody will be along shortly to verify your velocity concerns!;)

If that is a 45/70 than you can get some more out of it. Only if your shoulder holds up.

If not a 45/70 - I don't have a clue!

Yes 45-70 and I found that 36 grains is the most accurate load. At 50 yards it does quite well. Know that I have put a Williams Peep sight and a high Viz front sight on it I hope to do a little better and hit 100 yards. I was using a 6" shoot and see target yesterday. Saturday morning I will use a 100 yard target with the shoot and see. I did not take pictures or keep the targets from yesterday but if you look at this thread there are pictures from the load development. http://castboolits.gunloads.com/showthread.php?t=139891

You are running 1560 FPS - no real need to go any higher unless you want a little flatter trajectory. My hunting load with a 430 Cast and 4198 is running 1700 FPS. I have more powder room and according to quick load I can go to about 1800. I don't think my shoulder can take too many of those at a time!

[grubbylabs]

I am having a hard time thinking I need to go faster, that's a big hunk of lead to get moving. I might be able to find some thing with a different powder, but as far as 4198 goes, that's it. The pattern really opens up past 36 grains.

My Guide Gun has a sweet spot thereabouts w/ RX7, .5gr hotter and the eyepiece plays havoc with my eyeglasses. :holysheep I can't think of a reason to go hotter, several good reasons not to.

Reloader7 in about a 48 gr. with a 350 gr. FP works great for me. I've taken them up to 52gr., but those really set you on your heels. ;)

[TXGunNut]

My gr RD boolit gets pushed off the edge by 46 grs of RX7, can't figure out why 4198 didn't work for me. I think it's a better powder for that cartridge @ that velocity.

[grubbylabs]

Well I got back out today with the new peep sights and was able to shoot at 100 yards. I am quite happy with my load and the accuracy difference that peep sights made.

[TXGunNut]

Good to hear, there's something about peeps. Rainy mess around here today, glad to hear someone got out and enjoyed the day.

[grubbylabs]

Yup it was a very nice day, this also meant that the range was pretty busy.
