I finally got my .32 crockett this week and am going to try it out tomorrow (sat) I've bought some 777 but alot of what I've been reading in different threads has me kind of confused. With pyrodex you load same as black by volume, but it seems like, or maybe I'm misreading do I still load the same way? If I was to use 20grns. fffg black do I use 20grns 777? When I say 20grns I do mean by volume. Thanks for the help

You need to reduce the charge volume by 15% according to hodgdon.

I think the confusion on this point is because you CAN safely load equal volume of 777 for black, but you will get higher velocity with 777. The reason Hogdon says to reduce by 15% is to DUPLICATE black powder velocity, so your point of impact supposedly does not change. If you are working up new loads, I would guess it doesn't matter.

irndan: let me know your results from firing. I bought a crocket a while back but haven't tried shooting it yet. I had planned on trying Pyrodex because I wanted a lower velocity load. I would be interested in hearing your shooting results so I have an idea where to start load wise.

Be somewhat careful with the t7 - what Ramrod posted is correct - it does increase velocity when used equally - but it also increases "pressure" so if your are loading your BP close to max allowed using equal t7 may push you over the limits.

I have use t7 since it came out - I did and do recuce the charge (10-15%)but, over a period of time have developed loads that work great. There are some definite advantages to t7 over BP AND there are definite advantages of BP over t7 - you'll have to weigh them and make your own decision...

Well, I got to shoot yesterday and was quite pleased with the results. I started at 15 yrds. to make sure I would be on the paper and was about 2" high and 1 2/2" to the left. I had a very good three shot group that I could cover with my finger nail. Not bad right out of the box I used 20grns by volume 777 .310 ball and .010 patch. 2nd group using same powder same ball and .020 patch I had two touching, and one flier which I'm pretty sure was my fault. I think I need to try a .015 patch because the .010 patch was blown to bits and I did notice a difference in loading between the two patches. My shooting was cut short when I went to swab the bore and had my patch come off and get stuck. Dumb me didn't have a .32 patch puller! Live and learn anyway I am qiute pleased and was asked to post my results so here they are. I think next time Iwill start with the.015 patch and 25grns 777 then start playing with the bp to see what differences there will be.

A cap or 2 might blow the cleaning patch out, if not, pull the nipple and put a few grains of power in and reinstall the nipple and cap her up and try again.

No use going home early. :grin:

I tried at least half a dozen caps, tried putting a small bore brush down the barrel to snag it. none of my nipple wrenches I had fit the nipple so I didn't have much choice. I was real close to pouring about 5grns down the barrel with another patch but I wasn't sure if that would be ok I didn't leave by choice.

We all forget the small stuff sometimes, and it turns out to be the thing we need the most. :wink: I got a bag for all my different shooting, I have a Muzzleloading bag, a Shiloh Sharps bag because I shoot black powder in in 45-70 cases, a rifle bag and a pistol bag. I have all kinds of stuff related to specific shooting in the bags. I know it is a bit much, but I don't have to worry about forgetting something. I learned the hard way. I always use to forget something. On occasion I still do even with all them different bags. LOL :grin:

One thing, I am having a hard time finding any accessories to go with my .32 cal. Nobody around here carries anything that small. Any ideas or links to find the small stuff. Jag, patch puller, ball puller? I have all these things for my .50's but nothing for the .32

I would check with dixie,I got most of my jags from there along with a couple of cleaning rods. My Crocket likes 25 of Swiss 3f and a .320 rd( bag of tribble o buck) and it gets a little better than half inch at 25 yards...........Stay safe.King.....I would attempt the 20 with the swiss and see what you have. Swiss and 777 have roughly the same velocities when I chrono on them.............at least in my guns.

My Crockett likes a .315 ball and .018 pillow ticking. Pushed by 20 grains of Swiss FFFg, this combination will give me quarter sized groups at 35 yds. The .310 ball loaded a bit too loose and just doesn't shoot as accurately for me.
