Looking for some ideas to try. my name is Dylan i just got into SML over the summer with help of a friend thats been into the sport. i bought a H&R 45/70 conversion and i have been shooting the 250 barnes tez with a .06 veggie wad and 60 grain of h4198. These bullets measure .451 in diameter and are too small for my barrel they just slide all the way down. So i do a hard knurl to the tez and then run the bullet through a swinglok smooth die. i have a very tight spot about in my barrel about 4 inches above where my powder sits. i leave my bullet loose at tge muzzle because if the bullet is touching the rifling at the muzzle, id have to beat it down the barrel to seat. My question is, should i get away from the all solid copper bullets and go to a lead core bullet for better expansion to catch the rifling better? maybe the parker be? accumax? or parker emax?

Most h&r will accept a 250 sst or shockwave straight from the packaging.

The Pittman bullet is 452 so it might work good without sizing it al all. I would at least give them a try. Also I would try to find out why you have that hard spot to get past.. could it be a scope screw hole that is slightly to deep or pushed in from a screw being to long. ? This is just something to look for. You might be able to see it with the plug out.. if it's not that you may be able to lap it smooth to help with loading.

Every H&R 45-70 that I have seen were slightly tighter at the breech.

Do you want to stop using the 250 TEZ because it doesn't shoot accurately or just because of the sizing issue?

From wat i can see the barrel looks clear. Nothing looks out of the ordinary. I did mount the scope myself which is a nikon prostaff 5 4.5x18 40mm and mounted it to torque specs so i wouldnt over tighten or bust the reticles out. Seems to be ok. I did order some sample packs of the parker be, and a sample of the parker emax, and talked to kyle and bought a 25 pack of his accumax bullets and going to try and see wat would shoot better. Hoping for some better expansion inside the barrel because i have not tried a lead core bullet yet. Jeff i have been watching alot of your youtube videos trying to learn wat i can, i did see your youtube video of the h&r conversion and was very nice. I like the primer modules. I was unfortunate on this one i bought but it work. Some primers are a pain to push into the breech plug and after the shot i have to pull the primers out with a leatherman set of pliers.

Parker 275 BE (.451) will go down most barrels without sizing ,if your barrel is loose you also may have to knurl up and resize the BE's
The Parker BE have a jacket thickness of .015 and the Pittman Accumax .021
Both of these bullets will expand quicker then the all solid copper bullets you are using.
Good luck

Thanks. Thats wat im hoping for some better expansion. And if i have to knurl thats no problem. Maybe get lucky with a 452 and not have to knurl or size anything. When the bullets come in itll be off to the range and see wat happens

Hornady 200 or 225 will slide down ... with little resistance the parkers and pittmans will be more accurate for sure with a slight knurl and are true deer thumpers out of that gun wsitch it over to HIS igniton and it will be even more pleasurable too shoot .... i sold mine sometimes wish i had not !

You can open up your breech plug a little to keep from forcing your primers in . Take some sand paper and open up the pocket a little at a time . I normally use around 320 grit sand paper .

Would they be able to put the ejection clip back into the gun to be able to eject the primer modules like jeff makes on the h&r? Someone took the whole ejection clip out. Otherwise ill have to sand out the primer hole little bit at a time. I use the federal 209a primers and at the time of purchase the old owner was able to slide a primer in and take it out with his fingers, bought tge same exact primers and i have to let the action push the primer in cuz at times i cant push the primer in with my thumb, then the back pressure from ignition will keep the action from opening so i cock the hammer back and smack the spent primer to push it in just enough to open the action and then take it out with pliers. I love shooting the gun dont get me wrong, just little stuff that can be improved. Once i figure out these new bullets then ill focus on the ignition part of it and hopefully make it better

Try winchester primers they have a slight taper.I started using them in my apex,they seal better for me but not quite as hot of a primer so far no ignition problems my bp came from Jeff Hankins but I opted for the 209 due to my budget.

Are you using H.I.S. 209 system or the Arrowhead Plug? How do you like it? |

Looks like just a arrowhead plug. I seen jeffs ignition system on youtube and that is sweet. Would be awsome to have. But i have no leaks out of this one now. Its just tough putting primers in and taking them out. Havent had no ignition problems tho which is great

Get yourself a CVA priming tool.

I too have an H&R 45-70 Handi that has been converted to SML. I played with sabotless, but had the best results with saboted Barnes loads in my particular rifle.

Are you using H.I.S. 209 system or the Arrowhead Plug? How do you like it? If I remember right I think Jeff told me he used to make the plugs for arrowhead. I did have Jeff machine and install the 209 bp, it has a .035 bushing. It gets very minor leakage with the winchester, but I'm not trying to shoot at break neck speeds with this break action either. My shots where I hunt would never exceed 200yds. If I get the extra $$ I'll send the barrel back to him and have the H.I.S. module system installed as I'm sure it is less prone to leaking past primer or module. My apex is more accurate than my 7mag and my savage mlII. |
