    Unique is good w/light loads. 4227 is OK. IMR 4895 is good w/27-30 grn .Total diameter including powder coat should be .002 0ver actual bore size.

    I have shot the 170 grn #311041 gas checked, using perfecta brass, CCI large Rifle primer and 20 grns of Alliant 2400 powder. Wasn't that happy, shot on at 25 yards but left of factory at 100 yrds. Now trying everything the same but IMR 3031 powder at 36.7 grns for 2200fps. Haven't got to the range with the new load hoping for this weekend.

    Sorry it took so long to get back. Loaded some 168 grn Nosler match over 40.7 grn of 3031 for comparison. The answer is there is no comparison. It may be the short barrel of the Patrol wont give the longer burn needed for the lead bullets, they shot a foot lower at 100 yards. 35 grains of IMR3031 is a max load for the #311041 gas checked bullets I will load a few but not expecting much. I actually think it did better with the 2400 pistol powder may try that again.

    because the Patrol only has a 16inch barrel, I'm thinking the pistol powder may be the way to go. I'll let you know.;)

    Wouldn't pistol powder be too fast of a pressure spike for a rifle? I know full burn before the projectile leaves the barrel is preferable, I'm just wondering whether if a spike would be too faster over a more gradual rise. I'm relatively new to the reloading scene, so this is more of a question than anything. At this point, I think I fall into the "knows enough to be dangerous" category.

    There is an article in the August 2004 Handloader Ammunition reloading Journal that covers this topic. In it he gives some specific loads he made up using mil spec brass , CCI 200 Large Rifle primers and varies led bullets. Several handgun powders were used Trail Boss, Unique, 2400, Red Dot, Clays and Titegroup as well as standard rifle powder. Cup Pressure is the thing to worry about especially with the mil spec brass. The rifle he used had a 22 inch barrel. The Patrol as you know is only 16 so even closer to handgun length. When TC started putting out barrels with rifle calibers in their single shot pistols we learned that some rifle cartridges shined in the shorter length. The 35 Remington is an example. In the article he got his best accuracy at 100 yards using 20 grains of 2400 under a 176 Lyman 311467 lead bullet at 1779fps a 1.34inch group (308 Winchester Cast Bullet). Hope this helps.

    Some. So, as long as the barrel is shorter in length and there are no pressure signs at the cup, everything should be fine. Am I correct?

    The old loading manuals used to display the cup pressure of the load. The 308 Winchester is capable of standing 60,000 cup. The 762 NATO can only take 50,000cup. So it is important that hot 308 rounds not be shot in my Patrol for example. I saw the loads in the article were ok for mil brass so I went with it. My old Lyman manual states all 308 loads they list are ok for NATO so I trust them. I forgot to mention the idea behind using the lead loads is two fold; cheap ammo to shoot(20cents to reload not counting brass) and they are easy on the barrel so it lasts longer. These are range loads not hunting or competition. Rounds for an afternoon or day of fun.

    For my 308 MVP Patrol, I am reloading solely with Hodgdon H4895 using 43.1 grains, Lapua Brass, CCI #200 Large Rifle primers with Hornady 150gr FMJ and SP which is working just fine for me. I use to load my Savage 308 with IMR3031 and when I tried H4895 and it seemed to me & some buddies that the bullets Hit Harder and Faster at 100 yards.

    I knew that .308 is the hotter round of the two. Funny, my AR is chambered for .308 but my bolt rifle is chambered for 7.62 X 51. I still shoot .308 out of it but only factory rounds and when the brass does get reloaded, it won't be loaded hot.

    Well, the bad news is that with the 16 inch barrel my Patrol will not shoot lead worth a hoot. Shoots 6" low and all over at 100 yards. Guess I'll have to stick to the 168 BTHPs.
