Paul, (and mike and Fisher), well, i think all three of you make an assumption that shooting 100 to 120 grains of 2f under my RB will be physically punishing. Response to felt recoil is a very personal thing. All shooters have a different perception of it. One guy I shoot with won't go over 45 grains for non hunting loads and stays at 80 grains for deer and elk. He gets fine results just as you guys described with your 80 grain loads. But, the reason he loads as he does is recoil. He's no sissy. Played college football and is a physical guy but to him the recoil is highly objectionable. Point being that it's a subjective thing.

I don't get the accuracy vs charge argument. When we hunt, we need adequate accuracy and adequate power. For some guns/shooters that is a compromise of some type and others may find their best accuracy does not go with the level of power they think is adequate. IMO, it's about being "adequate" on both scores.

In fact, if my best accuracy load is 120 grains of 2f, then according to accuracy first believers, that should be my hunting load. OTOH, with the rifle and barrel I'll shoot this year, 80 grains of 3f will allow me to hold a 13 shot 6 inch offhand group at 50 yards. Even though it might improve a bit with a lighter or heavier charge, that is adequate hunting accuracy and adequate power level (chronos 1627 fps). But, since recoil does not bother me and since 100 grains will chrono 1853 fps, then going there might just be a good choice for me even though it may be looked down upon by some.

As far as chrono testing goes, I have done way more than any bp shooter needs to, including multiple brands, granulations, and lot#s. What I've found is indeed eye opening, but does not, IMO, shed much light on the killing power of these various loads and velocities.

As far as penetration tests go, while the idea is intrigueing, no artificial test medias are going to give an accurate picture of how a ball will penetrate in game. They may show some sort of relative penetration levels and while interesting, those same relative levels of penetration can change from media to media including the body of a game animal.

My only "test" media has been the deer and elk killed by myself and hunting partners with loads varying from 60 grains up to 120 on deer and 80 to 120 on elk. Within the same distances for the shot, the penetration differences were not worth mentioning. All of the above loads provided killing shots with penetration ranging from pass through to ball caught under the hide on the far side. All lethal!

So, as you can see, my opinion of what works does not vary much from what you guys think and as far as I'm concerned, the penetration testing is done and behind me. At the same time, since my 120 grain load kills them dead with adequate penetration as does my partners 80 grain load, what's the point of praising the ligher load over the heavier?

If recoil did effect me as it does those guys shooting 450 conicals over 150 grains of whiz bang, I'd sure not go there, but since it does not effect me then I sometimes do go there. It's just a matter of choice, just like my old indian friend told me.
 
I think if you set up a penetration test and try both your .50 grain target load, and the 80 grain hunting load in that .54, you will be surprised at how well your target load performs on the pentration test. I did mine at 15 feet. However, If I had been thinking ahead, I would have also moved my box back to at least 50 yards to see what the lower velocity for each ball would produce in penetration. At that time, we did not have a 100 yd range. Today, I do have access to such a range, and would take the box back to 100 yds, and try both loads. I still think that 50 grain charge will surprise you at how far it penetrates even at 100 yds.
 
I used one inch boards( actual dimension is 7/8" I believe) space one inch apart. I made up a " box " that was 24 inches long. I should have made it 36 inches long at least. One learns from one's errors.

These were pine boards, and I used a couple of standard cartridge guns to establish a comparison standard with the boards. A .22 CCI Stinger( 29 grain hollow point, high speed) went through 3 boards. I was shocked. My .30-06 shooting a Remington Factory 180 gr. Jacketed Soft point bullet went through 7 boards and into the eight. My .50 cal. ML using a target load of 60 grains of FFg went through 6 boards and dented the 7th. The same gun shooting a PRB over 100 grains FFg went through 6 boards and stuck in the 7th board, until I touched the flatten slug to see if I could remove it. I had barely touched it when it fell to the bottom of the box. I expected my heavier charge to give me more penetration. Both balls were flattened and mangled by going through that much wood. My .56-70 405 Factor jacketed soft point went through 11 boards, and split the 12th, hitting it sideways. The .50-140-550 conical went through all twelve boards, the last 3 sideways, and buried itself into a railroad tie about one inch. The bullet did not mushroom, and when we dug it out, you could easily see the grease grooves.

We shot a few more guns before the boards were so mangled that they were falling apart, but I don't recall them. I was there mainly to test my .50 cal. rifle and my buddy wanted to test his Sharps Rifle in .50-140.

If you plan to test more than a few shots, take a lot of extra boards. They seem to split up rather quickly when hit with the large balls or slugs.

I have a friend who has used sand bags to test hundreds of bullets and loads. His personal experience killing deer is his " standard " for comparison to the bullets we dig out of the sand bags. High speed does not do much to increase penetration in sand. A heavy slug does go much further than a lighter one, even when the lighter slug is going faster. I am not a fan of sand myself, as a penetration medium, as there is no correlation between how a slug acts in sand, compared to living flesh and blood. However, sandbags are easy to make, fast to put up in front of a backstop, and when you already have a frame of reference from your own experiences, you can make do with sand. Jim has been testing balls and bullets almost as long as I have been alive. He knows what he is doing. He also has been casting balls and bullets almost as long as I have walked, and he knows lead.

It would not suprise me much. I shot a large cow at about 30 yards. The ball went through and through. A 50 grain load would have done the job just as well and expended all the energy inside the animal. The major reason I use the heavier load is that I want to be dead on a the end of my range. The rifle shoots flat enough, with that load, that I can hold in the lights out to 100 yards and have it hit within a few inches through the whole range.

The 80 grain load would probably work well out to 200 yards. That load will knock over the large bear silouette at 200 yards. I don't feel comfortable shooting at an animal at that distance. There is too much chance of wounding the animal rather than getting a clean kill.

I had a good friend shot a mulie this year at 240 yards with a .45 and 85 grains 3F. He uses that rifle for 200 yard competion and is a VERY good long range shot. I would not have taken the shot but he did. The deer was looking at him straight on. The .440 RB went through the top of the chest and penetrated clear though to the heart. When the deer was cleaned the ball was lodged in the heart.

A well placed round ball is an awesome hunting projectal. It is accurate and gets the job done in the ranges that a muzzleloader should be used in.
 
I like recoil but for me I like to have as much acuracy as posible for my piece of mind when I'm hunting. If my best load is clover leafing then I know that I will get the shot in the vitals when I'm hunting. If off the bench I'm getting a four inch spread and then I add in the factor of shooting off hand and my patern opens up another 2 or 3 inches that is 6 or 7 inches overall which can place the shot when hunting outside the kill zone. It could be the diffrence from a kill shot to a wounding shot.
Personaly I like to eliminate as many factors or narrow down as many as posible for my own piece of mind.
My opinion only and you know what they say about opinions.
Regards F.K.

Mark,
80 grains of FFg is not that heavy of a charge. In fact, it's a very pleasant round ball load. As for accruate, one ragged hole at 50 yards and last week I shot a 3 shot group of 3/4 inch at 100 yards. Of course this is done from a bench. After one tour in Nam and 31 years in law enforcement, please save the manhood speech for some youngster. Too old to worry about such things :blah: .

You are right and I agree. These loads are pretty good. I use 90 grs of WANO PP (FFg) in all my ML, doesn't matter if .45, .50 or .54.And accuracy is very well.

I generally shoot 70 grains of 2f in my 50's for a starting load. That is pretty close to the sweet spot on every 50 I have ever tested with any powder I have used. I would not be afraid to hunt elk with that load, but it is a short range loading. From all reports over the last ten years or so, 80 sounds like the same load for the 54. That is where you will find the experienced folks loading them to.
If you want longer range, don't up the powder. Put a bigger bullet down the barrel. I stop with roundball at about 75 yards unless a perfect set up happens. If I expect a longer shot, I load a Lee Target (Trashcan) Minnie. It requires a pretty good load of powder to be accurate out of my slug gun, so it gets 90 grains of powder under it. I shoot the 50 at 70 grains 200 to 300 times a year. I shoot the slug gun about 10 times a year on a good year. Heck, I use 90 grains of 2f as the magnum charge in my 12 guage! Most of the time I only use 60 grains in it!
I really can't tell anyone that the lighter loads are better because I would not listen myself. I had to shoot my way back to them. I seem to remember shooting my way back as a good time all the way thru, and I wish you well on that journey!
 
Fisher King nailed it. Peace of mind = confidence which directly effects how well one shoots - all other factors aside.
