Size or Speed?
 

Which performs better? Watch this video, and you'll see speed is the answer.

I am a football/baseball coach - I'll take speed all day... the old saying 'speed kills'

Makes you wonder if in BP guns we shouldn't be going to small bullets and large powder charges.

One of my favorite.... Lehigh 40/200 grain 110 grains T7...



That 200 traveling @ 2200-2300 fps makes quite an impression when it gets where it is going...

Problem is if you go to light you loose energy very quickly. So they become less effective at longer ranges. Stacking powder doesn't work that well either as the bullet is out the barrel before all the powder can be burnt. Now if you had powder like smokeless that you could choose different rates of burn you might really be able to do something...

You don't think that BH 209 is all burning in heavy loads?

Even inefficient BP will still increase FPS when big loads are used. Even if half of it blows out the barrel.

BH is not effective as T7 when shooting light projectiles as BH is progressive burning so it is somewhat slow.

With T7 going from 110 to 120 grains I get a decent increase in velocity... going from 120-130 it is a very small jump, not even much worth the effort, so after 130 you are sending the rest out the barrel into the snow.... even at a 130 you shooting a % of that into the snow as unburnt powder...

Only a few of the smokeless options give a excellent burn percentage. Those typically spike psi faster and use much less powder. Slower powders need more powder to make enough psi but end up running out of barrel without some load work. Using smokeless some people use a duplex charge to over come this. A small booster load (10gr) of faster powder first then the slower powder on top of that.

Kinda makes me wonder what 10gr of T7 under 100gr+ of BH209 would do with a 200gr bullet in a 45cal ML. Im curious but im not sure i want to try that one.

Here is a video of a 200g SST at 1800fps

Here is a video of a 440g conical at 1450fps


The 200g bullet passed through 4 jugs, and was found on the ground. The 440g bullet passed through 5 jugs, and embedded into the phone books with a about 2" penetration.

I believe Ron has showed speed is not always the answer.

Your exactly right, but. You need to go to a 45caliber to get the full benefit. Like sabotloader said, 777 is better with lighter bullets in normal loads. But heavy loads of BH209 and 200grn bullets BH209 shines. My Chronagraph is still going up with 140grns of BH209 and a 200grn bullet. You will not see that with 777.

135grns of BH209 and 200grn bullet equals 2491 avg.

140grns of BH209 and 200grn bullet equals 2523 avg

Knight Rifles is the only ML company that allows 150grn loads by volume.
