Here is what I have found and used as a guide for loading my Contender 14" Shilen SS barrel made my MGM ( Match Grade Machines). These are MAX charges and in my barrel I could not quite reach these loads by about 1 grain and still feel comfortable. My barrel has a tight chamber and case life is outstanding. My whitetail deer load is this: WW case, Wolf LR Primer, 33 grs IMR 4198, 125 Nosler Ballistic Tip, OAL 2.825 and it averages 2670 fps will average 3/4" at 100 yards and HAMMERS DEER. I have a Weaver 2.5-8X28 scope on my barrel. I would suggest that you use NEW cases to fire form for yours. I tried some once fired cases and had a number of them split and the others did not last very long. New WW cases were fire formed with just a bunch of junk components I had laying around. 147 FMJ bullets pulled from military ammo, IMR 4320 powder and a starting load for the 30-30 WIN and the Wolf LR primers because I had a bunch. I loaded up 50 rounds went to the range fired 3 shots to get it on target at 100 yards. Proceeded to shoot up the rest off a sandbag and bench allowing two other people to shoot some and one fellow had never shot a Contender before. Ended up having 47 rounds in under 2" group at 100 yards. Talk about an accurate caliber and barrel. I have taken 7 whitetail deer with it in the past two seasons with the 125 BT load. Only two even took a step after being hit and they did not go over 3 jumps. You will love your 30-30AI.
30-30 Ackley Improved (T/C Contender Super 14) Data
Thanks Rog; I really appreciate the 30-30 AI data , I've been kicking around a couple of different 30-30 based cartridges I found a gunsmith that can open up my 30-30 win. 14 in. barrel to 30-30 AI
,I've found another real hot one in the past few days a - - 6m/m x 30-30 AI , from what I,ve seen so far it will push 75 grainers at 3400 fps. and 90 's at 3100 for this one I'll have to buy the whole barrel .
My barrel was a 1:10 twist, 14" long. It started life as a 30 Herrett that I had rechambered to the 30-30 AI.
Who did your rechambering?
"It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, who's face is marred by dust and sweat and blood, who, at the worst, if he fails, at least fails while daring greatly, so his place shall never be with those cold and timid souls who know neither victory nor defeat."
thank you for load data. i recently bought a new 30-30 a.i. factory contender super 14 barrel. bushnell 2-6x32 handgun scope. i worked up H4198 to 34.0 grains with a nosler 125 grn. ballistic tip. under 1 inch accuracy on every group i shot with it. new winchester brass i fireformed , rem 9 1/2 primer , with a c.o.a.l. of 2.810. no excessive pressure signs. cases fell out when contender was tilted back. thank you all for info !!!!
