Well you got me good and confused now, I do have a 450/458 GM barrel on my Henrys build, and hope to have it ready for its first round down the barrel with in the next mounth. But being new to this ,it was my understanding that the grease groove bullets should be the the same as the bore or a thousand bigger.I got some .450 520gr. Grease grove from buffalo arms and some .444 520gr swaged for paper patching ready to go. And a .451 volunteer mould. Going to need all the bullets I can get to try so I will be ready as I can be for the Oakridge shoot in March.
No confusion! For Target/Bench rest shooting i much prefer my paper patch bullets sized about 1-2 thou under bore, they glide down the bore with nearly the weight of my Ramrod alone (my thumb and index finger is plenty to load them) If i plan to hunt with my Paper Patched bullets i prefer a tighter fitting bullet therefore i DON’T finish size, i just wrap my paper, twist the tail, and load. Example: My .45 Green Mountain LRH i use .444 Bullet Diameter, 2 wraps of this particular onion skin paper i am using ads 7 thou to the overall diameter, bringing my .444 up to .451, If i am Target shooting i will run those wrapped .451 bullets through a .449 finish sizer, all i am doing is ‘ironing’ the paper a bit, the finished size after running through the .449 actually comes out at .450 (the paper will slightly ‘bounce back’ hence why they dont stay .449) i find that patched and sized bullets of .450 diameter load really nice at the bench in 2 of my 45 Cal rifles (1:30 twist, and my 1:18 twist) But for hunting i do NOT run them through the .449 sizer, just wrap and load.
This really comes down to a ‘Per Bore’ deal, One has to remember that not all bores are identical. I have a few different sizers per Caliber so i can adjust the fit. You really need to learn your bore, what fits well, and what don’t. I feel safe saying that ‘Most’ .45 Cal bores will be good with a .448-.449 Finish sizer. I have spoke with a few of our Top World Class shooters and was told that ‘Most Of the Time’ you will find best accuracy somewhere between 1-2 thou under bore.
Here is my reasoning for the Large band diameter Grease Groove Bullets i had made, A good friend of mine, Forum member Harleysboss was here to visit this summer and he left me some bullets to try in my .50 Cal, They are Called Bullshop, and made by Dan of Bullshop, They are a large band diameter Grease Groove design, i tried them in my .50 Cal and i was thoroughly impressed, not only with accuracy, but how good and tight they stayed all the way down my bore (AWESOME hunting bullet!) I liked that bullet so well that I contacted Bullshop Dan and asked him if he minded me Copying his design? He told me no problem, to go right ahead. I sent Tom at Accurate molds 1 of Dan’s .50 Cal Bullshop bullets and had him cut me a mold as close to the Bullshop bullet as he could possibly get it. Dan sells this particular bullet, and it’s a GOOD one! I ended up having Tom cut 3 molds for me .45, .50, and .54 Cal off the Original Bullshop bullet.
Here is the original Bullshop bullet, The 2 bottom (base bands) are .504, the 3rd band is .506-.507, and the top band is .508
Here is the Group that i shot with the Above Bullshop bullets
