Yes Tinman I was referring to the powder funnel...... didn't have the nomenclature quite right.

I looked at my tapered reamers and none will clean up all rough areas without getting too big at the top of the funnel. Its about a 1.250 long cut. However I do like your idea and will extend the taper as far as possible with what I have. The hole is now .195 so I should be able to polish out the remaining rough areas with silicone carbide.

This is what I used, and is pretty inexpensive. It is meant for plumbing work, but worked great to ream out the Dillon powder funnels to avoid bridging, especially with smaller calibers. It makes a more tapered "funnel". I have done all my rifle calibers, and have had the reamer for 20+ years. If you chuck the reamer up in drill press or mill at low speed, it takes all of 5 minutes to do. I leave about 3/8-1/2" at the bottom of funnel at the original diameter. Use lots of oil.

I've used CFE Blackout and 40 V-Max for 2-3 seasons of PD shooting with 20 VT.

18.0g yields 3400 with no signs of high pressure even at 90-100 degrees on the prairie.

Very accurate powder bullet combo in my rifle.... OCW target with loads in my album.

Only issue has been the very fine ball powder clings to the drop tube of the Dillon. I was shocked to recently find the tube ID coated with hardened powder. I had to use a bore brush to remove it. This was after loading only 4 pounds of powder or about 1500 rounds.

I'm going to polish the tube ID and ground the tube housing to try to eliminate the problem.

I'm gonna have to load some rounds with CFE BLK and give it a try. My RL-7 load is crazy accurate out of both rifles but the speed isn't where I think it should be. Maybe CFE BLK will bring it all together! So much reloading to do and simply not enough time. I'm still trying to find a load that my 17AH likes and another trip to the range today was a real disappointment. Back to the drawing board on that rifle.

Thanks for the tip on the reamer. I used an 11 degree that I have on hand and the funnel now works fine. I also drilled the remaining hole out to .199 to eliminate the remaining rough spots below the reamer cut and polished the ID with a bore brush wrapped in steel wool. I have a lathe so it was easy.

I'm going to order one of the reamers like you noted above, it will move the taper even lower into the funnel. I did find some on EBay also.

You can't read the Oehler chrono printout on my OCW target posted in my photo album but @ 18.6g the mean was 3511 with no perceivable pressure in my rifle. But you can see the groups expand as the load increases from 18.0g.

I chose 18.0g @ 3400 as my limit however because that is the maximum load speed I have seen for a pressure tested load in Accurate's loading manual. It also happened to be the optimum OCW load.

Primers are CCI 400's.

jeff for the life of me I can't see how this thread drifted so far away from your original post.
here ie loading data for a layman book.
10.75" barrel
40 gr jsp
h110 8.5-14.0 2545 fps max
imr 4227 13.0-16.5 2722 fps max
imr4198 15.0-18.0 2541 fps max
rx7 15.0-18.0 2287 fps


45 gr jsp
2400 12.5-14.7 26.11 fps
imr4227 13.0-16.0 2641 fps
ww680 15.3-18.8 2808 max
imr4198 16.0-18.0 2549 max
rx7 15.0-17.0 2111 max

no 50 gr loads but you can use the 52 gr load data for 50's

52 gr jhp
imr4227 12.0-15.5 max 2516 max
ww680 14.0-17.0 2589 max
imr4198 16.0-17.8 2497 max
rx714.5-16.5 2096 max


if you go to Hodgeon's website there are no cfe-blk loads under pistols but they are listed under rifle. if you must try the powder that might be a staring point. http://www.hodgdonreloading.com/data/rifle

As an update I've been up to 18.5 grains of CFE-B in the FB without excessive pressure using 40 vmax. The best accuracy was at 18.0 so that looks like it will be my load. In the 20 VT I'm now up to 19.8 grains of CFE-B under the 32 vmax and only slightly flattened primers. I'm going to stop here and experiment with the over all length with the 32 vmax. The rifle and pistol both clean up easily with Bore-tech Carbon Out and patches.

My XP100 likes about 18gr of 1680 with CCI450 primers with 40gr bullets. Your powder is the same speed and I don't know what primers you use, but the 450'shave a much thicker cup than the 400's have. I haven't had any pierced primers or sticky bolt lift so I think I could go a little hotter than that.
